(***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is active. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

[ANS thanks Barry Sankey G7RWY and Dave Johnson G4DPZ, AMSAT-UK Joint Secretaries for the above information] --------------------------------------------------------------------- CubeSat: Celebrating 20 Years of Transforming Space Access Twenty years ago, an invention emerged from the labs of Cal Poly San Luis Obispo that would change the face of space exploration forever. The CubeSat, a tiny satellite with the dimensions of a square tissue box, revolutionized access to space, making it more affordable and achievable for researchers and students alike. The brainchild of professors Jordi Puig-Suari and Bob Twiggs, the CubeSat was born out of the need to solve a crucial problem. While universities aimed to train students through hands-on experience, getting their satellites into space was a daunting challenge due to the limited access to rockets and the high costs associated with launches. The innovative solution was simple yet effective, the CubeSat. They designed a standardized, risk-containment mechanism where all the risk of potential failure would be confined within the small box. This not only addressed the rocket providers' concerns about carrying student-built satellites but also reduced the cost and time required to send satellites into orbit. The CubeSat's impact was profound and far-reaching. Almost every rocket launched into space today carries CubeSats on board. The small satellite became an open standard, meaning anyone could use it without any charges, promoting uniformity and standardization across the industry. Unlike traditional satellites that could take years and cost hundreds of millions of dollars to build, CubeSats presented a cost-effective alternative. Building a CubeSat was a fraction of the expense, and the standard's versatility allowed various scientific missions, ranging from Earth observation and mapping to space exploration. The CubeSat opened the doors to space for many countries that launched their first-ever satellites, including Colombia, Switzerland, Hungary, Vietnam, and more. Private companies also capitalized on the CubeSat revolution, stepping in as intermediaries between satellite creators and rocket providers. Companies like Maverick Space Systems acted as "Uber for satellites," arranging rides for satellites of various sizes, including CubeSats, on rockets for commercial and government clients. The CubeSat's impact also extended to educational institutions. Cal Poly's CubeSat Lab provided students with hands-on experience, allowing them to design, build, and even launch CubeSats. The educational aspect of CubeSats became so popular that high school students at Grace Brethren High School in Simi Valley also had a class on spacecraft engineering, learning about CubeSats and building AMSAT CubeSat Simulators (CubeSatSim). The CubeSatSim Project, led by Dr. Alan Johnston, KU2Y, AMSAT Vice President Educational Relations, is an initiative sponsored by AMSAT. It involves the development of a low-cost satellite emulator called CubeSatSim, designed with solar panels, rechargeable batteries, and UHF radio telemetry transmission capabilities. The CubeSatSim features a 3D printed frame and can be expanded with additional sensors and modules. The project aims to provide an accessible platform for educational purposes. Detailed documentation and build instructions are available on the project's Wiki at https://github.com/alanbjohnston/CubeSatSim. As the CubeSat celebrates its 20th anniversary, it stands as a testament to the power of innovation and the impact of an open standard in transforming an entire industry. What began as a solution to a niche problem has now become an integral part of space exploration, enabling researchers, students, and commercial ventures to access space like never before. The CubeSat's legacy is imprinted in space, as these tiny satellites continue to leave their mark on missions, both in orbit and beyond.

LEDSAT's primary objective is to demonstrate a LED-based payload for ground-based optical tracking. One of the notable features of LEDSAT is its digipeater capability, which allows it to store and retransmit digital messages sent to the satellite, effectively acting as a transponder for long-distance communication. When opening ARRL's TQSL (Trusted QSL) application, an "Update Available" dialog box will display if a newer configuration file is available. Simply click the 'OK' button to install the latest configuration file. You can easily determine whether a new version of TQSL or its Configuration Data is available by selecting the "Help" menu and clicking on "Check for Updates...". The latest version of TQSL (version 2.6.5) can be downloaded from https://www.arrl.org/tqsl/tqsl-2.6.5.msi. Additionally, the GreenCube Terminal program developed by Carsten Groen, OZ9AAR, now includes support for communications with the LEDSAT digipeater by utilizing the "Soundmodem for GreenCube" TNC application created by Andy Kopanchuk, UZ7HO. The latest release of the GreenCube Terminal program version 1.0.0.62 was provided on July 22, 2023. More information can be found at https://moonbounce.dk/hamradio/greencube-terminal-program.html.

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 satellite has been added to this week's AMSAT-NA TLE distribution: MRC-100 NORAD Cat ID 56993 IARU Coordinated Frequency: 436.720 MHz. (Thanks to Nico Janssen, PA0DLO for identification). The following satellite has decayed from orbit and has been removed from this week's AMSAT-NA TLE distribution: DO-111 (ARDUIQUBE/DIY-1) NORAD Cat ID 47963 decayed from orbit on 21 July 2023 per Space-Track.org [ANS thanks AMSAT Orbital Elements page 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.

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 also active (145.825 MHz up & down). 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.

From John, KC7JPC: I will be back in DN19 on August 9th and 10th. Will get on fm/linear while there. Evenings for sure but maybe some early morning passes as well. Will also be in dn29,dn39, dn36, and dn19 again the next week. August 14-18. Fm only and more than likely just the evening Tevel passes. Still need to do a pack up of gear on the motorcycle to make sure the radio fits in with the gear. From Mike, N8MR - I will be in EN57 roving to EN56 and EN67 Aug 4 - 12. On Aug 4, will activate EN66 on RS-44 during the 1713z pass, and may be on other adjacent sat passes. Prefer linear sats, but will be on FM sats. Skeds posted mainly via Twitter @MikeN8MR. Sked depends on wx, etc. All QSOs will be posted LoTW, using N8MR (no /p, /r).

[ANS thanks Alun Williams, writing for ElectronicsWeekly.com, for the above information] + On July 23, a SpaceX Falcon 9 rocket launched from Cape Canaveral Space Force Station with 22 additional satellites for the Starlink communications constellation. During the launch, the rocket created a temporary hole in the ionosphere, also known as a rocket exhaust depletion (RED), by releasing exhaust that interacts with charged oxygen atoms, creating a reddish patch. Although the damage is not permanent and mainly affects amateur radio signals, the increasing frequency of such occurrences due to the growing number of satellite launches has raised concerns among scientists about the potential impact on the ozone layer, as rocket exhaust releases various toxic chemicals into the atmosphere. Stricter controls for the launch services industry have been called for to address this issue. [ANS thanks Aditya Madanapalle, writing for News9 Live, for the above information] + The preparation for Ariane 6's inaugural flight is going well, as the teams completed a launcher preparation and countdown sequence successfully at Europe's Spaceport in Kourou, French Guiana on 18th July. The test included various critical tasks such as removing the mobile gantry, chilling down fluidic systems, and filling the tanks with liquid hydrogen and liquid oxygen. The launch chronology was also completed up to the ignition of the Vulcain 2.1 engine. During the 26-hour exercise, degraded and contingency modes were tested, demonstrating the launcher and launch base's proper functioning. Although the ignition of the Vulcain 2.1 engine had to be postponed to a later session, the overall performance of the full launch system was excellent. The teams are confident about the progress of the test campaign and are preparing for a long duration hot firing test in the summer.
