ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. *Please send any amateur satellite news or reports to: ans-editor [at] amsat [dot] org.* You can sign up for free e-mail delivery of the AMSAT News Service Bulletins via the ANS List; to join this list see: https://mailman.amsat.org/postorius/lists/ans.amsat.org/ ANS-056 AMSAT News Service Weekly Bulletins To: All RADIO AMATEURS From: Radio Amateur Satellite Corporation 712 H Street NE, Suite 1653 Washington, DC 20002 DATE 2024 FEB 25 Bob Twiggs Keynote Address at 2024 AMSAT Space Symposium Now Available For those who missed Bob Twiggs, KE6QMD, keynote address at the 2023 AMSAT Space Symposium, now is your chance to catch up on this delightful and informative presentation. You can view Bob’s 36-minute presentation at https://youtu.be/uDPJ4SHAF74?si=c9f3xM8G1KFUjZPw. Sorry, there are no advanced mathematical formulas or complex orbital mechanics to be found here. Bob is a consummate story teller who brings warmth and humanity to the pioneering days of amateur satellites. If you weren’t in Dallas for the live event, this is the next best thing to being there. Robert J. Twiggs is a professor of Astronautics and Space Science at Morehead State University. He is responsible, along with Jordi Puig-Suari of California Polytechnic State University, for co-inventing the CubeSat reference design for miniaturized satellites which became an Industry Standard for design and deployment of the satellites. Twiggs earned a Bachelor of Science in Electrical and Electronics Engineering from the University of Idaho in 1961 and a Master of Science in Electrical Engineering with a concentration in microwave devices from Stanford University in 1964. From 1985 to 1994, Twiggs was the director of the Weber State University Center for Aerospace Technology. He served as a consulting professor in the Stanford University Department of Aeronautics and Astronautics from 1994 to 2008. At Stanford, he established the Space Systems Development Laboratory. Bob Twiggs became a professor at Morehead State University in 2009 in an effort to push the PocketQube standard leveraging the university’s large aperture space tracking system, and to help develop a space economy in the state of Kentucky. In 2019, Twiggs designed and proposed another smaller, simpler satellite form factor called ThinSat which could enable high school students to design and build satellites.

While AMSAT finalizes its plans for reinvigorating its Ambassador program, it wanted to make immediately available a fresh set of handouts for use at hamfests, maker-faires, and so on. Some of the considerations to be factored into an updated program are the increased costs of printing and shipping small quantities of handouts here and there. Conversely, the cost of printing and shipping literature has to be balanced against the inevitable “waste” factor of literature simply tossed into, at best, a nearby recycling bin by passer-by’s who feel obligated to take a handout offered to them as they walk by a display. Considerable thought is being given to this situation. For a few recent hamfests, a few AMSAT Ambassadors have been testing the concept of displaying a poster with a QR code that interested parties can scan to download literature. Although it is too soon to say this approach is a smashing success, AMSAT Ambassadors testing the concept feel positive about the reaction of hamfest participants visiting their displays. In tests, a QR code on a small poster can be successfully decoded at up to 20 feet away. You can view or download the QR code poster at AMSAT Hamfest QR Code <https://www.amsat.org/wordpress/wp-content/uploads/2024/02/Scan-Here-QR-Pos…> . The QR code used brings the ham to a “landing” site of the AMSAT website. The landing site offers the person - A link to join AMSAT online, - A two-page summary brochure as to why they should join AMSAT, - A comprehensive brochure describing AMSAT activities, and - A link to the AMSAT Store to buy a downloadable copy of “Getting Started with Amateur Satellites.” You can view the landing page at https://www.amsat.org/getting-started-with-amsat/. This page has been specially formatted for use on smart phones. You can click on each of the images to view or download each of the documents or links. Since this is a test period for this approach, these pages are not cataloged on the web site. After we receive feedback from AMSAT membership and especially AMSAT Ambassadors, access to these documents and the QR code poster will be open to general membership. The AMSAT Ambassador team looks forward to your feedback on how to improve AMSAT’s presence at local and regional hamfests, maker-faires and other events that can boost interest in amateur satellites and AMSAT membership. Please send your comments and/or questions to info(a)amsat.org. If you are interested in becoming an AMSAT Ambassador, please send an email with a short resume to volunteer(a)amsat.org. [ANS thanks AMSAT for the above information.] ------------------------------ UK’s SaxaVord Spaceport to Launch Amateur Radio Satellites Two more amateur radio satellites, MARIA-G (HADES-F) and UNNE-1 (HADES-E), are planned to launch from the UK’s SaxaVord Spaceport later in 2024. Previously announced amateur radio payloads on the launch are: ERMINAZ-1U and -1V from AMSAT-DL GENESIS-MA and -ME from AMSAT-EA QUBIK 5, SIDLOC-PQ-1 and -PQ-2 from Libre Space Foundation *MARIA-G* A 1.5u Pocketqube. MARIA-G will offer radio amateurs around the world the opportunity to relay FM voice and AX.25 / APRS 300 / 1200 bps communications. The satellite will also transmit telemetry with its status and voice and CW messages. This all will be achieved by implementing a SDR based FM and FSK repeater. The FM / FSK repeater will be available all time and opened by squelch level without the need of a PL tone/CTCSS. Main mission for MARIA-G is to be a FM repeater but it will also include a simple guess game being implemented by students at Maria Guerrero High School in Collado Villalba – Madrid (Spain). The satellite will send a clue each week in CW so radio amateurs will have to solve the mystery by having all the clues. A small experiment, developed by Fraunhofer-Gesellschaft research organization (Germany) will also fly on the satellite to make proof of concept transmissions of a TS-UNB waveform from a low Earth orbit. It will transmit a TS-UNB message according to the ETSI standard ETSI-TS-103-357. It is intended solely as a research and development project with no commercial intent, all its data public and open. ITU modulation classification would be 100K W2DWW but the bandwidth will be narrowed. The operation of this experiment will be managed by AMSAT-EA. *UNNE-1* A 1.5u Pocketqube. UNNE-1 will offer radio amateurs around the world the opportunity to relay FM voice and AX.25 / APRS 300 / 1200 bps communications. The satellite will also transmit telemetry with its status and voice and CW messages. This all will be achieved by implementing a SDR based FM and FSK repeater. The FM / FSK repeater will be available all time and opened by squelch level without the need of a PL tone/CTCSS. A small guessing-game is being implemented by students of Universidad de Nebrija (Spain). The satellite will send a clue each week in its telemetry so radio-amateurs will have to solve the mystery by having all the clues. Game will be detailed in AMSAT-EA and Universidad de Nebrija websites. The main mission for the satellite is acting as a FM voice repeater although due to its SDR nature it can repeat data too. This satellite is based on the hardware of HADES-D (SO-121) that’s currently being used to amateurs worldwide. The guess game implemented by the University is a small challenge for the radio-amateurs and its mission is to make the reception of signals from the satellite fun for youngsters, expecting them to be future radio amateurs. Proposing a UHF downlink, VHF Uplink for FM voice, FSK data up to 1200 bps, APRS up to 1200 bps and FSK telemetry and experimental data up to 1600 bps and CW. These two satellites are part of the Erminaz mission, a joint effort by AMSAT-DL, AMSAT-EA and Libre Space Foundation. Planning a DLR/ESA launch from the UK SaxaVord Spaceport in Summer 2024 into 500/600 km polar orbit.

The radome will once again be dedicated to satellite and space research. AMSAT Deutschland e.V. and the Bochum Observatory are taking the positive experience of the anniversary conference in 2023 as an opportunity to inform AMSAT members and other space enthusiasts about current and future prospects for national and international space projects with a varied program. As the radome is also the location of ESA’s education office in Germany (esero Germany), they want to make the symposium even more attractive in future and at the same time focus even more on current European space travel. The planning so far envisages the following schedule: Friday, September 20, 2024 Come-together in the afternoon including short guided tours in the radome. Saturday, September 21, 2024 From 9:00 a.m. AMSAT symposium with lecture program. Amateur radio flea market in the radome. Sunday, September 22, 2024 From 10:00 a.m. General meeting Further information on the AMSAT-DL space conference in Bochum will follow in the course of 2024. The conference program is expected to be available on our website beginning in July. Speakers with interesting topics wanted, please get in touch!

Weekly updates are completely adequate for most amateur satellites. Elements in the TLE bulletin files are updated daily. TLE bulletin files are updated to add or remove satellites as necessary Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/ The following satellites have been removed from this week’s AMSAT-NA TLE distribution: CAPE-3 NORAD Cat ID 47309 Decayed from orbit on or about 17 February 2024 GRIFEX NORAD Cat ID 40379 Decayed from orbit on or about 22 February 2024 [ANS thanks Joe Fitzgerald, KM1P, AMSAT Orbital Elements Manager for the above information.] ------------------------------ ARISS NEWS Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.800 MHz worldwide. *Completed Contacts* Girl Scout Troop 1089, Sacramento, CA, direct via N6NA. The ISS callsign was NA1SS. The crewmember was Loral O’Hara, KI5TOM. The ARISS mentor is AA4KN. Contact was successful on Thursday February 22, 2024. The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down). If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. The packet system is reported to be active on the ARISS status page (145.825 MHz up & down) but the AMSAT satellite status page shows no recent contacts as of the time of this writing. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html [ANS thanks Charlie Sufana, AJ9N, one of the ARISS operation team mentors for the above information.] ------------------------------ Upcoming Satellite Operations No operations listed at this time. [ANS thanks Ian Parsons, K5ZM, AMSAT Rover Page Manager, for the above information.] ------------------------------ Hamfests, Conventions, Maker Faires, and Other Events AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events. CubeSat Developers Workshop 2024 April 23–25, 2024 Cal Poly, San Luis Obispo https://www.cubesatdw.org/ Dayton Hamvention 2024 May 17, 2024 – May 19, 2024 Greene County Fairgrounds and Expo Center 120 Fairground Road, Xenia, OH 45385 https://hamvention.org 38th Annual Small Satellite Conference Logan, UT, USA August 3-8, 2024 https://smallsat.org/ ------------------------------ Satellite Shorts From All Over + The European Space Agency Academy’s CubeSat Summer School is open for applications. Taking place over four weeks from 5 to 30 August 2024 at ESEC-Galaxia (Transinne, Belgium), applications are now open for university students with engineering, physics and business management backgrounds. During the Summer School, ESA and external experts will deliver an extensive mix of lectures and hands-on activities. The entire project lifecycle of a satellite mission will be covered, from design to verification, launch and operations, including typical milestone reviews and new methodologies. Students will be introduced to legal, cybersecurity, and economic aspects of space projects. The Summer School will even introduce space entrepreneurship skills, offering support in devising methods of turning a CubeSat into a viable and profitable business opportunity. More information at http://tinyurl.com/ANS-056-ESA-Summer-School. [ANS thanks the European Space Agency for the above information.] + NASA is developing a plan to deorbit the International Space Station (ISS) at the end of its lifetime, currently scheduled for 2030. Since the 356-foot-wide laboratory is too big to completely vaporize if left to naturally burn in Earth’s atmosphere, the space agency intends to send a US spacecraft to help deorbit the station and direct its reentry over the unpopulated South Pacific. The goal is to give the ISS an extra “space tug” to help it move more than it could with its own thrust, and guide the final burns for ISS to re-enter Earth’s atmosphere. The space tug is expected to cost $1 billion, agency officials had said earlier this year. Earlier this year, Russia agreed to stay onboard ISS through 2028, rather than its previous timeline of 2024, after which it may focus on building its own station in low-Earth orbit. Other partner countries have agreed to continue their presence through 2030, but it is not clear precisely how they will contribute to retiring the ISS. More information at http://tinyurl.com/ANS-056-ISS-Tug. [ANS thanks the SpaceRef.com for the above information.] + Martians Wanted: NASA has opened the call for a simulated yearlong Mars mission. If you’re looking for an extended vacation next year, NASA is seeking applicants to participate in its next simulated one-year Mars surface mission to help inform the agency’s plans for human exploration of the Red Planet. The second of three planned ground-based missions called CHAPEA (Crew Health and Performance Exploration Analog) is scheduled to kick off in spring 2025. Each CHAPEA mission involves a four-person volunteer crew living and working inside a 1,700-square-foot, 3D-printed habitat based at NASA’s Johnson Space Center in Houston. The habitat, called the Mars Dune Alpha, simulates the challenges of a mission on Mars, including resource limitations, equipment failures, communication delays, and other environmental stressors. Crew tasks include simulated spacewalks, robotic operations, habitat maintenance, exercise, and crop growth. More information at: http://tinyurl.com/ANS-056-Mars-Mission.

AMSAT NEWS SERVICE ANS-049 In this edition: * SpaceX Delays Crew-8 Astronaut Launch to Make Way for Private Moon Mission * Upcoming Rideshare Launch to Include Amateur Payloads * Bill Introduced to Eliminate Private Land Use Restrictions on Amateur Radio * Small Launch Companies Seek Niches to Compete With SpaceX Rideshare * Changes to AMSAT-NA TLE Distribution for February 16 * ARISS News * Upcoming Satellite Operations * Hamfests, Conventions, Maker Faires, and Other Events * Satellite Shorts From All Over The AMSAT News Service bulletins are a free, weekly news and information service of AMSAT, the Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. *Please send any amateur satellite news or reports to: ans-editor [at] amsat.org <http://amsat.org>* You can sign up for free e-mail delivery of the AMSAT News Service Bulletins via the ANS List; to join this list see: https://mailman.amsat.org/postorius/lists/ans.amsat.org/ ANS-049 AMSAT News Service Weekly Bulletins To: All RADIO AMATEURS From: Radio Amateur Satellite Corporation 712 H Street NE, Suite 1653 Washington, DC 20002 DATE 2024 Feb 18 SpaceX Delays Crew-8 Astronaut Launch to Make Way for Private Moon Mission NASA’s next astronaut launch will delay nearly a week to let a moon mission leave Earth first. NASA’s Crew-8 astronauts, who will launch on a SpaceX Crew Dragon, will fly to space no earlier than Feb. 28. The delay from Feb. 22 will make room for the expected launch of Intuitive Machines’ moon lander from the same launch pad at NASA’s Kennedy Space Center in Florida. Odysseus, a robotic lunar lander built by the Houston-based company Intuitive Machines, lifted off atop a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center (KSC) in Florida early in the morning on Thursday, Feb. 15. If all goes according to plan, Odysseus (designated IM-1) will touch down near the moon’s south pole on Feb. 22, becoming the first-ever private spacecraft to ace a lunar landing. Success would also be a big deal for the United States, which hasn’t been to the lunar surface since NASA’s Apollo 17 mission more than half a century ago. “NASA and SpaceX will continue to assess Crew-8 readiness and may adjust the Crew-8 launch date following a successful IM-1 launch,” agency officials wrote in a statement on Feb. 13, while announcing the delay. The astronaut mission will serve as relief for Crew-7, which flew to space on Aug. 26 for an International Space Station mission expected to last six or seven months. *SpaceX Crew-8 crew. From left to right: Roscosmos cosmonaut Alexander Grebenkin, NASA astronaut Michael Barratt, KD5MIJ, NASA astronaut Matthew Dominick, KCØTOR, and NASA astronaut Jeanette Epps, KF5QNU.* Crew-8 includes NASA astronauts Matthew Dominick, KCØTOR (commander), Michael Barratt, KD5MIJ (pilot), and Jeanette Epps, KF5QNU (mission specialist), along with Roscosmos cosmonaut and mission specialist Alexander Grebenkin. Both the ISS crew and the IM-1 launch are using a pad SpaceX leases at NASA’s Kennedy Space Center. The moon mission has a fairly narrow launch window as the IM-1 lander needs specific landing conditions to land at the lunar south pole, which is part of why the launch date for Crew-8 may be adjusted. Crew-8, as the name implies, is the eighth crewed operational mission by SpaceX that sends commercial crews to the ISS on NASA’s behalf. Starliner, the second vendor, may fly its first test crew in mid-April 2024.

In addition to a half dozen commercial payloads, two amateur satellites are on the launch manifest: SONATE-2 from Germany and CroCube from Croatia. *SONATE-2* SONATE-2 is a 6U+ CubeSat designed and built by the University of Wuerzburg in Germany. As for many university satellites, the mission objectives of the SONATE-2 satellite can be divided into three different parts: – The operation of an amateur radio payload – The development and operation of the satellite for the education of students. – The operation of a novel payload as a technology demonstration in space. The amateur payload of SONATE-2 consists of a VHF transceiver that was already built for the predecessor mission SONATE over the course of several student theses. For SONATE-2 additional student theses extended the transceiver functionalities. It will provide regular SSTV downlinks with images from the optical sensors included in the AI payload as well as an APRS digipeater and CW beacon. On the education side, the mission will serve as a foundation for different aspects of the university aerospace and computer science engineering program. In the context of practical courses, theses or as student assistants, students can participate in the development of all subsystems of the space and ground segment, including the amateur radio payload and the technology demonstration payload. In the context of mandatory lectures and exercises on space operations every student will also be included in the operations of the satellite. The German Aerospace Center (DLR) offers a School Lab for high school students at the location of our external ground station in Neustrelitz, Germany. Besides experiments on space and satellites, the School Lab includes amateur radio contacts to the ISS under the supervision of licensed local radio amateurs, which they wish to extend to other satellites like in this cooperation with the SONATE-2 mission. In addition to the amateur and educational mission parts, the SONATE-2 mission also has a research objective for the demonstration of novel artificial intelligence technology in the space environments. While the AI payload is mainly operated using a separate up/downlink in the space operation service in S-band, the satellite bus and the amateur payloads are operated in the amateur service. Housekeeping telemetry in the amateur service also contains status information of the non-amateur payload. Proposing CW, SSTV using Martin M1 and APRS downlinks on VHF and a 9k6 G3RUH AX25 telemetry downlink on UHF. Planning a launch into a 550 km Sun-Synchronous Orbit (SSO). More info at https://go.uniwue.de/hk. Downlinks on 437.025 MHz, 145.825 MHz, 145.840 MHz and 145.880 MHz have been coordinated by the International Amateur Radio Union (IARU). *CroCube* CroCube is a 1U CubeSat mission to support the Croatian, but also worldwide amateur radio community with many HAM services and activities. The mission’s goal is also to facilitate the technological development of Croatia, create an advanced society focused on prosperity and innovation, and increase participation in the global space sector. Also, drive Croatia into the space era, increase interest in astronomy and space projects, and develop STEM and tech entrepreneurship, create a platform for founding a space center in Croatia, increase investments and employment in robotics, technology and ICT and finally reduce unemployment and prevent brain drain. The CroCube satellite is designed for HAM radio activities. The main purpose is to provide services for radio amateurs in Croatia and worldwide, and also for students of technical universities to get hands-on experience with satellite communication and get radioamateur licences. One of the project goals is to popularize HAM activities across the common population, students and children in Croatia. CroCube will provide these HAM services: – AX.25 telemetry – CW beacon – Digipeater – Anniversary/special occasions AX.25 & CW messages for community engagement – Experimental SSDV transmissions – SATNOGS integration, decoder, dashboard Proposing a UHF downlink using 9k6 G3RUH GFSK with AX25 telemetry. Planning an Exolaunch deployment into a 510 km SSO. More info at https://drustvo-evo.hr . A downlink on 436.775 MHz has been coordinated by IARU.

When you purchase through* *AMSAT, a portion of the proceeds goes towards* *Keeping Amateur Radio in Space.* *https://amsat.org/product-category/hardware/* <https://amsat.org/product-category/hardware/> ------------------------------ Bill Introduced to Eliminate Private Land Use Restrictions on Amateur Radio U.S. Senators Roger Wicker (MS) and Richard Blumenthal (CT) introduced S.3690 on January 30, 2024, the Senate companion bill to H.R.4006, introduced last June. Both bills reflect the Congressional campaign efforts by ARRL to eliminate homeowner association land use restrictions that prohibit, restrict, or impair the ability of an Amateur Radio Operator to install and operate amateur station antennas on residential properties they own. Amateur Radio Operators repeatedly are relied upon to provide essential communications when disaster strikes, but their ability to do so is being impaired by the exponential growth of residential private land use restrictions that hinder their ability to establish stations in their homes with which to train and provide emergency communications when called upon. In announcing the introduction of S.3690, Senator Wicker said: “Because communication during natural disasters is often hindered, we should be making every attempt to give folks more options. Reliable access can make the difference between life and death in an emergency. Our legislation removes roadblocks for amateur radio operators looking to help their friends, families, and neighbors.” In a similar announcement, Senator Blumenthal stated: “Our measure will help clarify the rules so ham radio enthusiasts can successfully continue their communications. In the face of emergency or crisis, they help provide vital, life-saving information that allow listeners to properly and safely respond, but prohibitive home association rules and confusing approval processes for installing antennas have been an unnecessary impediment. The Amateur Radio Emergency Preparedness Act resolves these bottlenecks and ensures that radio operators can function successfully.” ARRL President Rick Roderick, K5UR, and Director John Robert Stratton, N5AUS, Chair of the ARRL’s Government Affairs Committee, both extended on behalf of ARRL, its Members, and the Amateur Radio community their thanks and appreciation for the leadership of Senator Wicker and Senator Blumenthal in their continuing efforts to support and protect the rights of all Amateur Radio Operators. [ANS thanks ARRL News for the above information] ------------------------------ Small Launch Companies Seek Niches to Compete With SpaceX Rideshare Small launch vehicle developers are working to carve out niches in a market for smallsat launches that is increasingly dominated by SpaceX’s Transporter rideshare missions. The Transporter missions, which fill a Falcon 9 often with more than 100 smallsats, offer per-kilogram prices significantly below dedicated small launch vehicles. SpaceX has seen high demand for those missions and announced plans last year for a related line of missions called Bandwagon that will go to mid-inclination orbits. “The Transporter program was created a few years ago with, in my opinion, the sole purpose of trying to kill new entrants like us,” said Sandy Tirtey, director of global commercial launch services at Rocket Lab, during a panel at the SmallSat Symposium in Mountain View, Calif. on Feb. 7. “Yet, we are still flying because we offer something unique.” That uniqueness, he argued, is the ability to fly missions to specific orbits not served by Transporter rideshare missions. An example is Rocket Lab’s next Electron launch, which will place into orbit the ADRAS-J inspector satellite for Astroscale. That mission requires a specific, precise orbit so that ADRAS-J can rendezvous with a derelict Japanese upper stage. *A Rocket Lab Electron launched four smallsats for NorthStar Earth and Space Jan. 31. Credit: Rocket Lab* “Electron is really the only vehicle capable of delivering such a complex mission on an expedited timeline,” Peter Beck, chief executive of Rocket Lab, said in a Feb. 7 statement about the launch, scheduled for Feb. 19 (New Zealand time). Rocket Lab said the specific launch time will be determined just a day before launch, with a near-instantaneous launch window. “Most of the missions that we fly are enabled by the fact that we offer dedicated services,” Tirtey said, citing the upcoming ADRAS-J launch. “There is no way you could do this on a rideshare.” Other panelists said they are targeting customers with specific requirements or needs that make them less price-sensitive than those who opt for the less expensive Transporter launches. That includes dedicated orbits and high reliability, said Pablo Gallego, senior vice president of sales and customers at Spanish launch company PLD Space. “We are offering a premium service for the ones that are willing to pay.” That argument, though, is in danger of being undercut by the combination of rideshare launches and orbital transfer vehicles (OTVs), which can take satellites to their desired orbit after being deployed from a Transporter or similar launch. Several companies are offering such vehicles and using them on Transporter launches. While that combination may still be less expensive than dedicated launches, it still doesn’t offer sufficient flexibility, launch providers argued. “We are excited to partner with a lot of OTV providers in providing that service to our customers, but it comes down to performance and how quickly you can get there,” said Robert Sproles, chief technology officer of launch services company Exolaunch. “If it takes you multiple months on orbit to get to that final destination, there’s a strong argument to be made to going dedicated.” Tirtey said that maneuvers that require plane changes can take months to complete, adding that current OTV providers have yet to demonstrate the ability to perform such complex maneuvers. “It could be useful, but you can’t expect a revolution because of physics.” However, on another panel at the conference Feb. 6, industry officials said they see challenges for small launch vehicles coming from SpaceX’s Starship, which promises much greater performance at significantly lower prices. “If you’re a smallsat company, your business model should be looking forward to the model of the Starship rideshare,” a scaled-up version of Falcon 9 rideshare, said Abhishek Tripathi, director of mission operations at the University of California Berkeley’s Space Sciences Lab and who previously worked at SpaceX. He said that the introduction of Starship could change how spacecraft are designed, allowing the use of heavier but cheaper materials and components. “You can throw mass and power and volume at your problem and thereby scale up your satellite bus and still be cheap.” [ANS thanks SpaceNews for the above information] ------------------------------ *Want to fly the colors on your own grid expedition?* *Get your AMSAT car flag and other neat stuff* *from our Zazzle store!* *25% of the purchase price of each product goes* *towards Keeping Amateur Radio in Space* *https://www.zazzle.com/amsat_gear <https://www.zazzle.com/amsat_gear>* ------------------------------ Changes to AMSAT-NA TLE Distribution for February 16 Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs.

Visit the JAMSAT website at https://www.jamsat.or.jp/ to learn more. (ANS thanks Mikio Mouri, JA3GEP, JAMSAT Newsletter Editor, for the above information.) + An unspecified defect in early model Starlink satellites has prompted SpaceX to preemptively deorbit the units before they potentially fail and become hazards in low Earth orbit. The company has already initiated the disposal of 406 units from the nearly 6,000 satellites launched to date. Among these, 17 are currently non-maneuverable but are expected to naturally decay and eventually burn up in Earth’s atmosphere in the coming years. However, the decision to deorbit a large batch of approximately 100 satellites within a brief amount of time is certainly out of the ordinary. (ANS thanks Gismodo for the above information.) + The European Space Agency’s Cluster mission, which has spent 24 years revealing the secrets of Earth’s magnetic environment, is coming to an end. The first of the four satellites in the Cluster quartet, named ‘Salsa’, will reenter Earth’s atmosphere in September 2024. This month, spacecraft operators carried out a series of manoeuvres to ensure this reentry will take place over a sparsely populated region in the South Pacific. The end of the Cluster mission offers a rare chance to study the safe atmospheric reentry of four identical satellites under different conditions. (ANS thanks The European Space Agency for the above information.) + Copernicus, the Earth observation component of the European Union’s Space programme, has confirmed that January 2024 was the warmest January on record. Samantha Burgess, Deputy Director of the Copernicus Climate Change Service (C3S) said: “2024 starts with another record-breaking month – not only is it the warmest January on record but we have also just experienced a 12-month period [with a mean global average temperature] more than 1.5°C above the pre-industrial reference period. Rapid reductions in greenhouse gas emissions are the only way to stop global temperatures increasing.” (ANS thanks https://climate.copernicus.eu for the above information.) + Voyager 1, humanity’s most distant scientific outpost, is currently careening away from Earth at 17 kilometers every second and unable to transmit useful scientific or engineering data back to us across nearly a light-day of space. The problem with the 46-year-old spacecraft cropped up back in November, when Voyager started sending gibberish back to Earth. Flight controllers have determined that the problem lies within the one remaining flight data system (FDS) computer on board, most likely thanks to a single bit of corrupted memory. The team has tried rebooting the FDS, to no avail. With most of the engineers who originally built the spacecraft long gone now, the team is treading very carefully.

The discussion centered around ESA's initiative to collaborate with the amateur satellite community in defining a prospective payload for Medium Earth Orbit (MEO) or Geostationary Orbit (GEO). The ESA's involvement aims to build upon the success of the QO-100 payload in geostationary orbit, fostering innovation and technological advancements. During the FOSDEM conference, the ESA Satellite Communications Group outlined preliminary ideas, stressing the significance of engaging with the Software-Defined Radio (SDR) community. The primary objectives include consolidating requirements, exploring diverse payload options, addressing user segments, and thoroughly examining financing, procurement, and operational scenarios for a potential MEO/GEO amateur payload. The project's scope encompasses the consideration of various payload options and trade-offs, encompassing aspects such as frequency bands, analog or digital transmission, on-board SDR/Linux/GPU-box configurations, potential applications, technical risks, inter-satellite links, geographical coverage, degree of centralization, and educational components. [cid:[email protected]]<https://www.amsat.org/wordpress/wp-content/uploads/2024/02/Support_for_MEO_…> Proposed Planning for ESA MEO/GEO Amateur Payload. [Credit: Frank Zeppenfeldt, ESA Satellite Communications Group] To ensure a comprehensive and well-informed approach, the ESA plans to actively involve the amateur community. This engagement seeks to gather valuable input on lessons learned from the QO-100 experience, amateur requirements and interests, as well as suggestions for payload options. The consultation process extends to reaching out to AMSAT and other relevant groups, alongside dialogues with satellite operators, primes, and various stakeholders. Looking ahead, the ESA has outlined a timeline for the project. In March 2024, the agency intends to solicit input from the amateur satellite community and other stakeholders, guided by valuable insights from the AMSAT community. By May 2024, detailed payload options will be presented for discussion at the European Space Research and Technology Centre (ESTEC) in the Netherlands, with the support of technical expertise. More information from this presentation including the ten page Slide Deck can be found https://fosdem.org/2024/schedule/event/fosdem-2024-2084-design-of-a-follow-…. The culmination of this extensive process is expected in September 2024 at the World Satellite Business Week, where dedicated discussions with satellite operators will be organized. The ESA envisions proposing a selection of payload options at a subsequent FOSDEM conference in 2025, further demonstrating the collaborative commitment of ESA and the amateur satellite community to propel advancements in satellite communications and explore innovative possibilities for future amateur satellite payloads in both GEO and MEO orbits.

There have been no recent developments regarding the fate of this widely-used satellite since AMSAT Italia's announcement on February 2nd that the Italian Space Agency is considering revisiting the decision to decommission it. Originally designed for scientific purposes and placed in MEO orbit, GreenCube satellite has successfully completed its primary mission. The "Save the GreenCube Satellite Digipeater" petition initiated by Peter Goodhall, 2MØSQL, has gained significant traction, garnering over 2,000 signatures to date. The petition, accessible at https://www.change.org/p/save-the-greencube-satellite-digipeater, remains open for further support. [cid:[email protected]]<https://www.change.org/p/save-the-greencube-satellite-digipeater> Save the GreenCube Satellite Digipeater petition continues to gather signatures. [Credit: Change.org] The support from the amateur radio satellite community for the GreenCube IO-117 digipeater has been exceptionally robust. Carsten Groen, OZ9AAR, has introduced significant enhancements to his GreenCube Terminal in the latest Version 1.0.0.88, which can be accessed at https://moonbounce.dk/hamradio/greencube-terminal-program.html. Notable improvements encompass SatNOGS Integration, GPS Integration, "AMSAT Sheriff" Wyatt, and Live World View. The Oscarwatch GreenCube Reporter map, developed by Peter Goodhall, 2MØSQL, is available at https://oscarwatch.org/greencube, serving as a valuable resource for monitoring real-time activity on GreenCube. The recent success of the TX5S Clipperton Island DXpedition, which made numerous GreenCube digipeater contacts, can be attributed to these enhancements and the collaboration of operators adhering to the recently released IO-117 Code Of Conduct recommendations. To get a comprehensive view of the considerable amateur radio activity on the GreenCube digipeater, you can explore the GreenCube IO-117 Users Map curated by Doug Papay, K8DP, accessible at https://www.google.com/maps/d/viewer?mid=1Y7O-rWll2QHFTjbBa4ThmZ3AG9ls8Io. According to the latest update, GreenCube has facilitated digipeating for 1,576 unique callsigns and 999 unique grids. This encompasses digipeats from 121 DXCC entities, all 50 US states, all 47 JA prefectures, and 36 out of 40 CQ Zones. Since its launch in July 2022, 846 ground stations have contributed over 3.4 million telemetry and 6.2 million digipeater frames to the SatNOGS database. The top five contributors to the database, in terms of total submissions, are Doug Papay, K8DP, with 1.1M submissions; Dave Webb, KB1PVH, with 734k submissions; Dave Fisher, KGØD, with 576k submissions; Shige Nasu, JH8FIH, with 507k submissions; and Jacob Mol III, N8JCM, with 498k submissions. [cid:[email protected]]<https://www.google.com/maps/d/viewer?mid=1Y7O-rWll2QHFTjbBa4ThmZ3AG9ls8Io&ll> GreenCube IO-117 Users Map [Credit: Doug Papay, K8DP] GreenCube IO-117 exemplifies the strong backing the amateur radio satellite community extends to satellite missions incorporating telemetry data alongside communication opportunities for radio amateurs. The forthcoming challenge for satellite missions lies in soliciting input from the amateur radio satellite community and ensuring tools are available prior to launch. Leveraging its unique orbit and capabilities, GreenCube has enabled many to attain challenging awards on satellites, such as ARRL DXCC, ARRL Worked All States (WAS), and the JARL Worked All Japan Prefectures Award (WAJA). AMSAT, alongside thousands of amateur radio operators, remains steadfast in their support for the GreenCube mission, with hopes for its sustained success in the future.

This milestone achievement follows Japan's SLIM lunar mission, which saw the deployment of two lunar excursion vehicles, LEV-1 and LEV-2. LEV-1, designed for hopping mobility, features direct-to-Earth communication capabilities via UHF band antennas from the MINERVA and OMOTENASHI projects. Equipped with two wide-angle visible light cameras, LEV-1 conducts lunar exploration while carrying essential science payloads, including a thermometer, radiation monitor, and inclinometer, providing valuable insights into lunar conditions and terrain. It actively receives data from its companion rover LEV-2, and this information is transmitted to Earth using its 1 Watt UHF circular polarization antenna, employing Morse code on a IARU coordinated frequency of 437.410 MHz. [cid:[email protected]]<https://www.amsat.org/wordpress/wp-content/uploads/2024/02/JAXA_SLIM_LEV1_L…> <https://www.amsat.org/wordpress/wp-content/uploads/2024/02/JAXA_SLIM_LEV1_L…>JAXA's SLIM mission delivered probes, LEV-1 and LEV-2, to the lunar surface. [Credit: Japan Aerospace Exploration Agency] Decoding efforts by Daniel Estévez, EA4GPZ, and others have shed light on the telemetry data transmitted by LEV-1. Utilizing captures from the 25-meter radio telescope at Dwingeloo in the Netherlands, Estévez identified the telemetry format as PCM/PSK/PM with a symbol rate of 64 baud and a 2048 kHz subcarrier. The residual carrier is modulated in amplitude with Morse code, introducing an unusual element to the signal. Despite challenges posed by amplitude shift keying in the signal, a phase-locked loop (PLL) has proven effective in tracking the phase of the residual carrier. Estévez's decoding journey involved unraveling the CCSDS coding, a task that posed initial challenges. While the IARU coordination sheet hinted at bitrates and coding specifics, the signal's unique characteristics required a thorough investigation. The BCJR decoder, a tool used successfully in previous decoding efforts, validated the presence of convolutional coding. The output provided log-likelihood ratios, offering confidence in the correctness of the convolutional code. Further investigations led to the identification of the syncword 0xFAF320, a crucial element in understanding the structure of the transmitted frames. [cid:[email protected]]<https://www.amsat.org/wordpress/wp-content/uploads/2024/02/LEV-1_Demodulato…> <https://www.amsat.org/wordpress/wp-content/uploads/2024/02/LEV-1_Demodulato…>GNU Radio LEV-1 Demodulator GUI displaying Residual Carrier Amplitude from LEV-1 [Credit: Daniel Estevez, EA4GPZ] One intriguing aspect of the decoded data is the Morse code modulating the residual carrier in amplitude. Despite initial confusion caused by an inverted amplitude representation, subsequent analysis revealed recognizable Morse code sequences. The meaning behind these Morse code transmissions remains a mystery, inviting collaboration from the broader radio amateur community and the LEV-1 team. As decoding efforts continue, the telemetry data's contents remain unknown, emphasizing the need for more documentation from the LEV-1 team. The spacecraft's utilization of the amateur satellite service and its completion of the IARU coordination process suggest that technical documentation may become publicly available in the future. More details on the ongoing efforts to decode LEV-1's amateur radio transmissions can be found at Daniel Estévez's website at https://destevez.net/2024/01/trying-to-decode-lev-1/. This achievement in establishing the first amateur radio station on the Moon opens up new possibilities for lunar communications and amateur radio enthusiasts worldwide. The collaborative efforts of radio amateurs contribute significantly pave the way for future advancements in space communication technologies.

Commanded by former NASA astronaut Michael López-Alegría, KE5GTK, the Ax-3 mission lifted off on January 18 and included pilot Walter Villadei, IUØRWB, along with mission specialists Alper Gezeravcı, KJ5DIY, and Marcus Wandt, KJ5COO, who represented the European Space Agency. Despite a nearly week-long extension due to poor weather, the spacecraft's reentry and descent went according to plan, marking Axiom Space's third private astronaut mission to the ISS. This mission served as a precursor to Axiom's installation of commercial modules on the ISS, which will form the basis of a future standalone space station. Additionally, SpaceX announced plans for five or six crewed missions in 2024, including Ax-4 and NASA's Crew-8 and Crew-9 missions, while the Polaris Dawn mission, led by billionaire Jared Isaacman, is expected to launch in the summer for a historic Crew Dragon spacewalk. (ANS thanks Jeff Foust, SpaceNews, for the above information) + NASA's PACE satellite, aimed at studying ocean health, air quality, and climate change effects, was successfully launched into orbit at 1:33 a.m. EST on February 8th aboard a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station in Florida. Signal acquisition was confirmed five minutes post-launch, with the satellite performing as anticipated. With instruments to study microscopic life in oceans and particles in the atmosphere, PACE aims to uncover crucial factors affecting global warming, aligning with the Biden-Harris Administration's climate agenda. The satellite's capabilities include tracking phytoplankton distribution globally and monitoring atmospheric aerosols and cloud properties. PACE's data will significantly advance understanding of the Earth system, particularly in relation to climate change impacts on oceans and phytoplankton dynamics, offering valuable insights for coastal communities and industries. (ANS thanks NASA for the above information) + NASA is preparing for the launch of Intuitive Machines' first lunar lander, Nova-C, as part of the CLPS initiative and Artemis campaign. The launch is scheduled for no earlier than 12:57 a.m. on February 14 from Kennedy Space Center in Florida. The Nova-C lander is expected to land on the Moon on February 22, carrying NASA science and technology instruments for various purposes. Live launch coverage will be available on NASA+, NASA Television, the NASA app, and the agency's website, starting from February 12. The payload includes instruments focusing on plume-surface interactions, space weather/lunar surface interactions, radio astronomy, precision landing technologies, and communication/navigation for autonomous navigation technologies. NASA's virtual guest program allows the public to attend the launch virtually, and social media engagement is encouraged with the hashtag #Artemis. The CLPS initiative aims to deliver science and technology to the lunar surface through partnerships with U.S. companies, with a cumulative maximum contract value of $2.6 billion through 2028. (ANS thanks NASA for the above information) + Virgin Galactic has temporarily halted its operations after a small part, an alignment pin, unintentionally detached from the mothership of its rocket-powered space plane during the Galactic 06 space tourism flight on January 26. The company assured that the part's loss did not compromise the mission's safety. The alignment pin is crucial for pre-flight procedures, ensuring the spaceship aligns with the mothership. Virgin Galactic discovered the issue during routine checks and promptly notified government regulators on January 31. The Federal Aviation Administration (FAA) will conduct a mishap investigation, requiring Virgin Galactic's final report and corrective actions approval before resuming flights. The alignment pin's absence did not affect the safety of the successful Galactic 06 mission, and the company plans to provide further updates after the FAA review for the upcoming Galactic 07 mission in the second quarter of 2024. (ANS thanks Jackie Wattles, CNN, for the above information) + Ongoing efforts persist in the bid to resolve the critical computer glitch affecting NASA's Voyager 1, the most distant human-made object in space, which has disrupted telemetry data transmission since November 14. The glitch, impacting the Flight Data Subsystem (FDS) developed five decades ago, has prevented access to vital information regarding the spacecraft's propulsion, power, and control systems. Suzanne Dodd, the Voyager project manager, acknowledges the severity of the situation, emphasizing the urgency of addressing the issue due to Voyager 1's age and declining nuclear battery power. A dedicated team of experts is actively crafting a plan to transmit commands aimed at isolating and potentially correcting the corrupted FDS memory. The unique challenge lies in the absence of simulators for testing commands, making decision-making a complex process requiring a delicate balance between thorough analysis and prompt action. Despite the intricate troubleshooting process, NASA remains resolute in its commitment to resolving the issue and ensuring the continued success of the historic Voyager 1 mission.

AO-92 was a 1U CubeSat developed and built by AMSAT. It carried a single-channel transponder for mode U/v in FM and also had an L-band converter (the AMSAT L-band downshifter experiment), which allowed the FM transponder to be switched to an uplink in the 23 cm band. In addition to the transponders, the satellite carried the following scientific and technical payloads: - High Energy Radiation CubeSat (HERCI) built by the University of Iowa - Camera Experiment built by Virginia Tech - MEMS GYRO Experiment built by Penn State-Erie The satellite had a single whip antenna for the 70 cm and 23 cm bands (uplink), as well as an antenna for the 2m band (downlink). AO-92 was launched on January 12, 2018 at 03:59 UTC on an Indian PSLV XL rocket, along with the main payloads Cartosat-2F, NovaSAR-S, and 31 other small satellites from the Satish Dhawan Space Center, India. At 05:17 UTC, the antennas were deployed over the North Pole and the satellite began to operate. At 05:28 UTC the first telemetry was received. On the 03:25 UTC pass on January 26, 2018, AMSAT Vice President – Engineering Jerry Buxton, N0JY, announced that AO-92 had been commissioned and formally turned the satellite over to AMSAT Operations. AMSAT Vice President – Operations Drew Glasbrenner, KO4MA, then declared that AO-92 was open for amateur use. *Rick Behma, VE4AMU, working AO-92 in Mode L/v with a Kenwood TM-941 mobile transceiver and Comet CYA-1216E yagi crossed with 2 meter Arrow II elements.* In addition to a very popular U/v transponder, the satellite provided a couple of unique capabilities. First was the L-band downshifter experiment, which was generally activated for 24 hours each Sunday while the satellite was able to support it. Pre-launch estimates suggested that approximately 100 watts ERP would be required to access the satellite, but much lower power outputs proved to be usable. Many stations operated through the satellite with radios such as the Alinco DJ-G7T at 1 watt of output into handheld antennas of between between 10 and 16 elements. At least one station reported accessing the satellite with just a simple whip antenna on 23 cm. The camera, developed by students at Virginia Tech, also proved to be popular and delivered many good pictures, with the last photos received on September 19, 2020. An archive of all of the photos captured by ground stations can be found at https://www.amsat.org/tlm/showImages.php?id=4. <https://www.amsat.org/tlm/showImages.php?id=4> The distance record on AO-92's U/v mode was 5,011 km - a transatlantic QSO between F4DXV and VE1VOX that took place on August 10, 2020. The record via the L/v mode was 4,202 km between OA4/XQ3SA and XE1MEX on June 3, 2020. By early 2021, the aging NiCd cells - having been purchased in the early 2010s along with the rest of the Fox-1 battery cells - had degraded to the point where the satellite was entering safe mode on every eclipse. It was rarely operational in recent months. The transponder was occasionally turned on, but usually defaulted into "Safe Mode" at the next eclipse. The last telemetry frame was received from the satellite on October 27, 2023 at 01:36 UTC. By every measure, AO-92 was a tremendously successful amateur radio satellite, providing educational and research benefits to AMSAT's university partners, as well as providing several years of reliable FM communication for amateurs. Its useful life far exceeded the average operational lifespan for commercial or educational CubeSats. *[ANS thanks Joe Fitzgerald, KM1P, AMSAT Orbital Elements Manager, and Paul Stoetzer, N8HM, AMSAT Executive Vice President, for the above information]* ------------------------------ The First Amateur Radio Station on the Moon *A rendering of the Smart Lander for Investigating Moon (SLIM) on the lunar surface. [Japan Aerospace Exploration Agency, image]* The Japan Aerospace Exploration Agency (JAXA) successfully landed their Smart Lander for Investigating Moon (SLIM) on January 19, 2024. Just before touchdown, SLIM released two small lunar surface probes, LEV-1 and LEV-2. LEV-2 collects data while moving on the lunar surface, and LEV-1 receives the data. The JAXA Ham Radio Club (JHRC), JQ1ZVI, secured amateur radio license JS1YMG for LEV-1, which has been transmitting Morse code on 437.41 MHz since January 19. The probe uses a 1 W UHF antenna with circular polarization and is transmitting "matters related to amateur business." Radio amateurs have been busy analyzing JS1YMG's signal, with Daniel Estévez's, EA4GPZ, blog <https://destevez.net/2024/01/trying-to-decode-lev-1/> introducing the method and extraction results for demodulating Morse code from the signal, as well as extracting the code string. It's unclear how long signals will be heard. JAXA has said that SLIM was not designed to survive a lunar night, which lasts about 14 days, and is due to return in a few days. SLIM was launched on September 6, 2023, and landed on January 19, 2024, with the mission of analyzing the composition of rocks to aid research about the origin of the moon. SLIM's landing made Japan the fifth country to achieve a soft touchdown on the moon. The landing was achieved with exceptional precision -- within 180 feet of its targeted touchdown location. *[ANS thanks ARRL News for the above information]* ------------------------------ *The 2024 Coins Are Here Now!Help Support GOLF and Fox Plus.**Join <https://www.amsat.org/join-the-amsat-presidents-club/> the AMSAT President’s Club today!* <https://www.amsat.org/join-the-amsat-presidents-club/2024-coin-both_586/#ma…> ------------------------------ Lunar Excursion Vehicle (LEV-1) Amateur Telemetry Received The Japan Aerospace Exploration Agency (JAXA) confirmed on January 20, 2024, that the Lunar Excursion Vehicle (LEV-1), a small robot deployed from the Smart Lander for Investigating Moon (SLIM), successfully conducted activities on the lunar surface. The telemetry data were sent directly from the small robot. According to telemetry data, after deployment from SLIM, LEV-1 executed planned leaping movements and direct communication with ground stations, including inter-robot test radio wave data transmission from the Transformable Lunar Robot (LEV-2, nicknamed "SORA-Q"). On the other hand, image acquisition on the lunar surface has not been confirmed as of now. Currently, LEV-1 has completed its planned operational period on the lunar surface, depleted its designated power, and is in a standby state on the lunar surface. While the capability to resume activity exists contingent on solar power generation from changes in the direction of the sun, efforts will be maintained to continue receiving signals from LEV-1. Both LEV-1 and LEV-2 have become Japan's first lunar exploration robots. Additionally, the small LEV-1 with a mass of 2.1 kg (including a 90g communication device), achieved successful direct communication with Earth from the moon. This is considered as the world's smallest and lightest case of direct data transmission from approximately 380,000 kilometers away. Furthermore, the accomplishment of LEV-1's leaping movements on the lunar surface, inter-robot communication between LEV-1 and LEV-2, and fully autonomous operations represent groundbreaking achievement. It would be regarded as a valuable technology demonstration for future lunar explorations, and the acquired knowledge and experience will be applied in upcoming missions. Moreover, the transmission of UHF band radio waves from LEV-1 as part of outreach efforts has encouraged participation from amateur radio operators globally, and we have been receiving reports of successful signal receptions. This initiative provided an opportunity for the public to be directly engaged in lunar exploration missions. We would like to extend our sincere gratitude to everyone involved in the LEV-1 mission. LEV-1 has an International Amateur Radio Union (IARU) coordinated downlink frequency of 437.410 MHz. A detailed report on receiving and decoding LEV-1 telemetry has been prepared by Daniel Estevez, EA4GPZ/M0HXM. It can be found at https://destevez.net/2024/01/trying-to-decode-lev-1/ An earlier summary of LEV-1 design and specifications is at https://robotics.isas.jaxa.jp/lev /LEV_HAM_Club.html. *[ANS thanks the Japan Aerospace Exploration Agency (JAXA) and Daniel Estevez, EA4GPZ/M0HXM, for the above information]* ------------------------------ AMSAT CubeSatSim Beta Release – v1.3 You might have heard about it or seen it at Hamvention or Symposium, but the official release of the new Beta CubeSatSim hardware and software is finally here!!

Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/ This week there are no additions or deletions to the AMSAT TLE distribution. *[ANS thanks Joe Fitzgerald, KM1P, AMSAT Orbital Elements Manager, for the above information]* ------------------------------ *Need new satellite antennas? Purchase an M2 LEO-Pack from the **AMSAT Store! <https://amsat.org/product-category/hardware/>**When you purchase through **AMSAT, a portion of the proceeds goes towards **Keeping Amateur Radio in Space.* ------------------------------ Request to Reconsider Decommissioning of IO-117 Under Evaluation by Italian Space Agency On Thursday, January 25, 2024 S5Lab posted on X that the GreenCube (IO-117) Digipeater would be permanently deactivated on February 5th. Designed and developed by students of Sapienza University of Rome, IO-117 is the first satellite to carry an amateur radio payload into a Medium Earth Orbit (MEO) of approximately 6,000 km. The message from S5Lab read: *Dear Friends,* *After one year and a half of operations, it is time to conclude the GreenCube operations with the planned de-commissioning activities. After the conclusion of the nominal experiment and with the digipeater payload active for more than one year, we will perform the passivation operations for the satellite.* *The planned passivation operations will be executed on Monday, 5 February 2024, at 00:00 UTC. From that day, GreenCube will be completely passivated and the digipeater will be switched off for good.* *We want to thank everyone that endorsed, supported or participated in the mission and the radio amateur community that enthusiastically became a true part of our project. We hope that GreenCube will somehow be part of your memories of radio amateurs, space engineering enthusiasts, and we hope to involve you soon in many more adventures.* *Thanks once again for the unbelievable memories shared together… See you soon!* *The GreenCube Team at S5Lab* That afternoon, AMSAT sent a letter to S5Lab <https://www.amsat.org/amsat-responds-planned-decommissioning-io-117-greencu…> expressing the organization's desire to leverage our decades of experience and work with S5Lab, AMSAT Italia, other AMSAT organizations, and the amateur satellite community at large to overcome any obstacles, regulatory or otherwise, to keeping IO-117 in service for as long as possible. AMSAT-DL, AMSAT-F, and other amateur satellite organizations also expressed similar sentiments. Peter Goodhall, 2M0SQL, began a petition on change.org <https://www.change.org/p/save-the-greencube-satellite-digipeater> that garnered over 1,500 signatures from amateur radio operators around the world in one week. On the afternoon of Friday, February 2, 2024, AMSAT Italia made the following announcement: *AMSAT Italia would like to inform the amateur community that its request to the Italian Space Agency, the owner of the GREENCUBE satellite, to reconsider its decision of decommissioning the satellite is under evaluation.* *Waiting for its decision, IO-117 is still operational.* *The GreenCube satellite was born as a scientific experiment placed in MEO orbit which successfully concluded its mission.* *IO-117 is the HAM Radio part of the satellite consisting of a digipeter which was promoted by AMSAT Italia and coordinated by IARU-R1.* *At the moment AMSAT Italia is committed to promoting the continuation of the mission for the HAM Radio part of Greencube.* *AMSAT Italia BoD* During its lifetime, IO-117 has proved to be a popular resource, allowing amateurs all over the world to obtain ARRL's Worked All States (WAS) and DX Century Club (DXCC) awards via satellite and to boost their VHF/UHF Century Club (VUCC) grid totals. A strong presence by Japanese amateurs has allowed many to work all the Japanese prefectures. A few DXpeditions, such as TX5S to Clipperton Island, have also brought gear for IO-117 along and provided rare DX entities via satellite. Multiple future DXpeditions also plan IO-117 activities. AMSAT is hopeful that the satellite's lifetime can be extended. *[ANS thanks AMSAT-UK, AMSAT-DL, AMSAT-IT, AMSAT, Peter Goodhall, 2M0SQL, and S5Lab for the above information]* ------------------------------ ARISS News Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.800 MHz worldwide. *Lilburn Elementary School, Lilburn, GA, direct via K4RGK* The ISS callsign is presently scheduled to be NA1SS The scheduled crewmember is Jasmin Moghbeli KI5WSL The ARISS mentor is K4RGK Contact is go for: Wed 2024-02-07 14:24:10 UTC 57 deg *School of Telecommunications Engineering, ETSIT Valencia (Universitat Politecnica de Valencia), Valencia, Spain, direct via EA5RKP* The ISS callsign is presently scheduled to be OR4ISS The scheduled crewmember is Loral O’Hara KI5TOM The ARISS mentor is IKØUSO Contact is go for: Fri 2024-02-09 08:12:46 UTC 31 deg *School TBD, Russia, direct via TBD* The ISS callsign is presently scheduled to be RSØISS The scheduled crewmember is Nikolay Chub The ARISS mentor is RV3DR Contact is go for 2024-02-15 08:20 UTC The Service Module radio is temporarily stowed. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down), If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html *[ANS thanks Charlie Sufana, AJ9N, one of the ARISS operation team mentors for the above information]* ------------------------------ Upcoming Satellite OperationsIO-117!!
