(***) 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 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour 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 sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. 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 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 ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general.

I will be monitoring the contact on Wednesday to the Kopernik laboratory. When the transmissions and contact are finished if the astronaut switches to the cross band repeaterand is free I will be there to try to make a qso with them from fn35cl as they pass over my qth in quebec canada.Can you please pass on my message to the ISS.

ARISS conducts 60-100 of these special amateur radio contacts each year between students around the globe and crew members with ham radio licenses aboard the ISS. The Kopernik Observatory & Science Center is a non-profit informal educational institution that promotes interdisciplinary education in the fields of Science, Technology, Engineering and Mathematics (STEM). This year is the 32nd summer of Kopernik STEM camps for students between 2nd and 12th grades. One of the camps offered this summer is entitled “Welcome Aboard the ISS”, where rising 5th and 6th grade students will learn about what it takes to become an astronaut, how they train for a mission and what research is being done on the ISS. Opened in 1974, Kopernik is celebrating its 50th anniversary as a STEM education resource in the region. Kopernik’s resources include three permanent telescopes, a heliostat, weather station, three classrooms, computer lab, portable planetarium and amateur radio station (K2ZRO). It also offers an outreach program in which its educators bring programs directly into the classroom. Kopernik is the home of the Kopernik Astronomical Society and the Binghamton Amateur Radio Association (W2OW) whose members are supporting observatory staff in the set up and radio station operation during this ARISS contact. This will be a direct contact via amateur radio allowing students to ask their questions of astronaut Matthew Dominick, amateur radio call sign KC0TOR. The downlink frequency for this contact is 145.800 MHz and may be heard by listeners that are within the ISS-footprint that also encompasses the relay ground station. The amateur radio ground station for this contact is in Vestal, NY. Amateur radio operators using call sign K2ZRO, will operate the ground station to establish and maintain the ISS connection. The ARISS radio contact is scheduled for July 31, 2024 at 2:17:25 pm EDT (NY) (18:17:25 UTC, 1:17 pm CDT, 12:17 pm MDT, 11:17 am PDT).

How does training underwater compare to the feeling of weightlessness in space? Does it actually feel pretty similar? 2. Looking out to space from the ISS, in what ways does it look different from a night sky on Earth? 3. Is artificial gravity just science fiction or a possibility in the future? 4. Does the ISS have any engine powering it forward? 5. How did they keep the ISS in orbit before there were astronauts on it and in between missions? 6. If the sun is the center of our solar system, and gives heat and light to the other planets, why is space cold and dark and not bright and hot? 7. What does a sunrise look like on the ISS? 8. What does Space sound like? 9. How long was your training for this ISS mission? 10. What's it feel like to experience a rocket launch? 11. What was your inspiration to want to become an astronaut? 12. What is the most challenging thing you have encountered as an astronaut on the ISS? Did you create a solution or overcome it? 13. How do you get enough air on the International Space Station? 14. Do you eat food from a bag? 15. Can I go to space? 16. Is it hard or easy to pick things up in the vacuum of space? 17.

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 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour 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 sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

This initiative, a collaboration between the Israel Space Agency (ISA) and Tel Aviv University, has been a key educational tool, providing practical experience in satellite technology to students across Israel. Launched in January 2022 on the SpaceX Falcon 9 Transporter-3 mission, the TEVEL satellites were part of a broader effort to promote STEM education. The CubeSats, built to the 10x10x10 cm standard, were used for various missions including scientific data collection, amateur radio communication, and technology experimentation. The project aimed to enhance students' understanding of satellite technology and prepare them for careers in the space industry. [https://www.amsat.org/wordpress/wp-content/uploads/2024/07/Students-Assembl…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/07/Students-Assembl…> Students assembling a satellite as part of the TEVEL program. [Credit: Israel Space Agency] In addition to their educational value, the TEVEL satellites played a significant role in the amateur radio community. Equipped with radio transponders, they allowed amateur radio operators worldwide to communicate via satellite, fostering international collaboration and technological experimentation. This feature provided a unique platform for enthusiasts to engage in satellite communication. As the satellites now re-enter Earth's atmosphere, this phase marks the end of their operational lives. The reentry process, which involves the satellites burning up upon reentry to prevent space debris, is being monitored by both educational teams and the broader space community. This final stage offers a valuable learning opportunity for students tracking the satellites' descent and analyzing the data. [https://www.amsat.org/wordpress/wp-content/uploads/2024/07/TEVEL-One-Throug…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/07/TEVEL-One-Throug…> All eight TEVEL CubeSats are expected to decay from orbit in the next few weeks. [Credit: Nanosats.eu] Looking ahead, David Greenberg, 4X1DG, has announced a new TEVEL mission featuring nine additional satellites, continuing the educational and amateur radio goals of the original initiative. The decommissioning of the TEVEL satellites highlights the importance of responsible satellite disposal to minimize space debris and ensure the sustainability of space operations. The success of the TEVEL project sets a precedent for future educational satellite initiatives, demonstrating how hands-on learning can be integrated with practical space missions. As the satellites complete their final descent, they leave behind a legacy of inspiration and international collaboration in both educational and amateur radio fields.

Among these missions was PariSat, a project that highlights the ingenuity and dedication of the Garef Aérospatial club. This amateur space club, comprised of young engineers aged 15 to 25, has been working diligently on satellite testing, with the goal of exploring how different materials handle heat dissipation in space. The core of the PariSat experiment is to determine which materials are most effective at dissipating heat in the harsh environment of space. The project, however, is not just about the scientific results but also about the educational journey for the young engineers involved. Based in a modest building near the Georges Carpentier stadium in Paris's 13th district, the club members work after school, applying their passion for space to design and build their satellite experiment. [https://www.amsat.org/wordpress/wp-content/uploads/2024/07/PariSat_Captures…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/07/PariSat_Captures…> Earth image captured by an adapted GoPro camera used on PariSat. [Credit: Garef Aérospatial] PariSat features eight small square plates, each just 4 cm wide, which function as space radiators. These plates were chosen to test various properties such as material composition and color, and their responses to heating and cooling. Equipped with temperature sensors, each plate provided data on "black-body radiation" during the nearly three-hour flight of Ariane 6's upper stage. This data will help validate the Stefan-Boltzmann law of thermal radiation, a principle discovered in 1884. In addition to the scientific experiment, PariSat includes a photo component. The team has adapted a GoPro camera for space use, which is controlled by a module entirely designed by Garef Aérospatial. This camera, featuring a fisheye lens, captured stunning images of Earth, showcasing the planet's curvature and adding a visual dimension to the mission. [https://www.amsat.org/wordpress/wp-content/uploads/2024/07/Ariane_6_Payload…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/07/Ariane_6_Payload…> Five experiments gathered data while attached to the Ariane 6's upper stage during its inaugural flight. [Credit: ESA] PariSat is part of a larger set of five experiments, including Peregrinus, Sidloc, LiFi, and YPSat, which also remained attached to the Ariane 6's upper stage during its three-hour flight. These experiments gathered data as the upper stage's orbit was adjusted by the Vinci engine, which can be restarted multiple times. The collected data was transmitted back to Earth and received by the Swedish Space Corporation's telemetry station in Kiruna, Sweden. As the Garef Aérospatial team begins analyzing the data, the PariSat mission serves as a testament to the capabilities of young engineers and highlights the potential for youth-led initiatives in space science. With this mission, the team looks forward to future projects, driven by the experiences and successes gained from their participation in Ariane 6's first flight.

This development comes as part of a contract awarded to SpaceX on June 26, valued at up to $843 million. The new spacecraft, known as the United States Deorbit Vehicle (USDV), was detailed by NASA and SpaceX officials at a briefing on July 17th. The USDV will be based on SpaceX's existing Dragon spacecraft but will feature a redesigned and larger trunk section with additional thrusters. Specifically, the USDV will have 46 Draco thrusters, including 16 for attitude control and 30 for the maneuvers required to lower the ISS's orbit. Sarah Walker, SpaceX's director of Dragon mission management, explained that the enhanced trunk section is twice as long as the regular one. [https://www.amsat.org/wordpress/wp-content/uploads/2024/07/SpaceX-United-St…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/07/SpaceX-United-St…> NASA presented the concept of the US Deorbiting Vehicle designed by SpaceX on July 17th. [Credit: SpaceX] The new trunk will house engines, propellant tanks, power generation, and other systems, storing six times the propellant of the current Dragon spacecraft and generating three to four times the power. "It's almost a spacecraft in and of itself," Walker noted. Once completed, NASA will own and operate the USDV, which will be launched to the ISS shortly after the station's final crew arrives. After its arrival and successful checkout, ISS controllers will allow the station's orbit to naturally decay. The final crew will depart when the station's altitude decreases from its current 400 kilometers to 330 kilometers. The ISS's orbit will continue to decay over approximately six months before NASA uses the USDV for a final controlled deorbit, targeting a remote ocean corridor about 2,000 kilometers long. [https://www.amsat.org/wordpress/wp-content/uploads/2024/07/Crew-6-Dragon-Ca…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/07/Crew-6-Dragon-Ca…> The SpaceX Dragon capsule Endeavour which flew the Crew-6 mission on March 2nd, 2023. [Credit: SpaceX] Dana Weigel, NASA ISS program manager, mentioned that debris from the station, ranging in size from a microwave oven to a sedan, is expected to survive reentry and splash down in this corridor. The USDV will have an estimated mass of over 30,000 kilograms, including 16,000 kilograms of propellant. Due to its size, it will require a heavier class of rocket than the Falcon 9 currently used for Dragon missions. NASA plans to procure the launch vehicle separately at least three years before the launch. SpaceX expressed readiness to support the launch if given the opportunity. Northrop Grumman was the only other company to bid on the USDV. NASA's source selection statement indicated that Northrop's bid was significantly higher in price and rated lower in both mission suitability and past performance compared to SpaceX. Ken Bowersox, NASA associate administrator for space operations, expressed satisfaction with the proposals received, noting he was pleased with the submissions from SpaceX and Northrop Grumman.

It is designed for educational purposes and features an amateur radio SDR payload. The satellite will offer telecommand uplink and telemetry/digital image downlink capabilities. Harbin Institute of Technology, known for developing successful amateur radio satellites like LilacSat-2 and DSLWP-B, has created a new SDR-based transceiver for ASRTU-1. This transceiver will provide communication resources, including a V/U FM transponder, UHF telemetry downlink, and a 10.5G image downlink. Scheduled to launch from Vostochny Cosmodrome on November 2024, ASRTU-1 will operate in a 530km sun-synchronous orbit with coordinated downlinks on 436.210 MHz, 435.400 MHz, and 10460.00 MHz and a repeater uplink on 145.875 MHz.

This upcoming launch, expected in August, will be the most ambitious to date and aims to build on the success of previous flights. The Super Heavy booster, measuring 233 feet tall, fired its 33 Raptor engines at full thrust for about 20 seconds during the static test at SpaceX's Starbase facility in Texas. Starship, which has been selected by NASA for the Artemis 3 lunar mission, is designed as a fully reusable system capable of carrying humans to Mars. Unlike SpaceX's Falcon 9, the Super Heavy booster is intended to return directly to its launch pad, where it will be caught midair by the launch tower's "chopstick" arms. With each test flight achieving progressively more, SpaceX aims to test the booster catch system in the upcoming launch, marking a significant advance towards rapid reusability and future missions.

This milestone marks a significant step in preparing for the Artemis-2 mission, which aims to return humans to the moon for the first time in over fifty years. NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen are slated to launch on this mission as early as September 2025. Upon arrival at KSC, the core stage was transferred to a self-propelled transporter and moved into the iconic Vehicle Assembly Building (VAB). Engineers will soon begin processing the stage for stacking operations, involving the integration of the twin Solid Rocket Boosters (SRBs) and the spacecraft. The Space Launch System (SLS) rocket's twin boosters and the core stage's four RS-25 engines will generate nearly 9 million pounds of thrust at liftoff, propelling Artemis-2 and its crew to the moon. (ANS thanks Mike Killian, AmericaSpace.com<https://www.americaspace.com/>, for the above information) + NASA astronauts Butch Wilmore and Sunita Williams will remain at the International Space Station (ISS) with no set return date due to ongoing technical issues with Boeing's Starliner capsule. The astronauts departed for the ISS in early June on a test mission expected to last about a week, but faulty thrusters and helium leaks have delayed their return. Despite some thrusters now functioning normally and the leaks being stable, NASA and Boeing are still not ready to schedule their departure. NASA assures that the astronauts are not stranded and the technical issues do not pose a threat to the mission. Engineers are conducting tests, including on a spare thruster in New Mexico, to understand and resolve the problems. Steve Stich, NASA's commercial crew program manager, emphasized the priority of the astronauts' safety and the consideration of backup return options. (ANS thanks Anna Betts, The Guardian<https://www.theguardian.com/>, for the above information) + SpaceX is set to resume Falcon 9 launches as early as July 27 following the completion of an investigation into an upper stage anomaly from the July 11 launch. The mishap, which resulted in the rocket's upper stage failing to perform a second burn and stranding Starlink satellites in a low orbit, was attributed to a liquid oxygen leak caused by a cracked sense line. This crack was due to engine vibration fatigue and a loose clamp. The resulting leak led to ice buildup and excessive cooling of engine components, causing a hard start and subsequent damage to the engine hardware. SpaceX has implemented immediate fixes and proposed long-term solutions, and the FAA has determined that there are no public safety issues, allowing launches to proceed. SpaceX is targeting July 27 for the next launch, with two more launches tentatively scheduled for July 28.

Thanks for the frames, JoAnne! The one you got the other day came in REALLY handy...so you just never know the value of your efforts to get a working system and copy some frames. A reminder--the Transponder is OFF and will remain so for a while, while we help UMaine get the science data from their satellite. A teaser--a quick test suggests that the linear transponder operation looks pretty promising ;) Another reminder--getting our stations "up to snuff" to copy MESAT1 is good, fun, work! Consider copying MESAT1 telemetry a good benchmark for how well you can receive on 70cm. Happy telemetry collecting! 73, Mark L.

Thanks Chris! I had good copy on the beacon and decodes were flowing nicely during the Saturday morning pass. My camera tab on FoxTelem shows a few lines of the image. I'll hope for stronger signals later today. The higher power and continuous transmission made final tweaks a lot easier :-) Also on the IC-9700 I found that I've got use the MAIN RX (and not the SUB RX) for FoxTelem to get the data. I use 435.798 as the initial frequency as N8MH had recommended previously.

The MESAT-1 team are continuing to test and commission the satellite. It is currently in Health Mode transmitting continuously and the downlink power is now about 6dB higher. So it should be easier to hear and decode. If you have had trouble decoding it then now is a good time to try again. You may have seen some data from the on board Multispectral Camera Saturday morning. This was test data as part of the commissioning process. The team will attempt to capture and transmit new science data on the 01:53 UTC and 12.25 UTC passes over North America tonight and tomorrow. 73 Chris VE2TCP / G0KLA / AC2CZ -- Chris E.

ARISS conducts 60-100 of these special amateur radio contacts each year between students around the globe and crew members with ham radio licenses aboard the ISS. School Story: Nara City has a long history, with its capital established approximately 1,300 years ago. In addition, Nara Prefecture has many world heritage sites and is an international tourist city. This will be the first time ARISS School Contact will be held in Nara Prefecture. We selected the contact members from Sakyo Elementary School and Tsubai Elementary School in Nara City. This will be a direct contact via amateur radio allowing students to ask their questions of astronaut Mike Barratt, amateur radio call sign KD5MIJ. The downlink frequency for this contact is 145.800 MHz and may be heard by listeners that are within the ISS-footprint that also encompasses the relay ground station. The amateur radio ground station for this contact is in Nara, Japan. Amateur radio operators using call sign JK3ZNB, will operate the ground station to establish and maintain the ISS connection. The ARISS radio contact is scheduled for July 29, 2024 at 7:52:51 pm JST (Japan) (10:52:51 UTC, 6:56 am EDT, 5:56 am CDT, 4:56 am MDT, 3:56 am PDT). The public is invited to watch the live stream at: https://www.youtube.com/watch?v=BQrUHun__6o *_______________________________* As time allows, students will ask these questions: 1. Yasuka (12) Can you see lightning on earth from space? 2. Haruto (9) What do you eat in space? 3. Rinto (10) Is the earth really green when seen from space? 4. Haruna (9) What kind of training does it take to go to space? 5. Yusei (11) How do you dispose of toilet waste? 6. Kohei (10) Have you ever seen any space debris while working outside the ISS? 7. Kippei (8) Can you write with a pen in space? 8. Sawako (12) What do you look forward to every day? 9. Seita (11) Is there any dust inside the space station? 10.
