Re: Request for Assistance on LiPo Battery Specifications

Hi Gustavo. FYI. I have seen several of the 'flat' versions of "space qualified" Lithium Polymer batteries fail for no apparent reason. If you still have a choice, I would suggest the metal enclosed Li-Ion 18650 cells. Never seen a failure with those and we've launched them on a Falcon 9, so Space-X are OK with them. (JY1-Sat) You may want to try AAC-Clyde for a Li-Poly data sheet. Or GOMSpace / ISISpace for a 18650.If you can't find the exact spec, you could always quote flight heritage using a specific battery supplier that they are familiar with. - However, that probably will not work if you've just purchased one off the shelf from Digikey etc. GL 73 David G0MRF On Thursday, 5 December 2024 at 10:49:52 UTC, Gustavo Carpignano via AMSAT-BB <amsat-bb(a)amsat.org> wrote: Dear Group, Our amateur radio team is currently building a cubesat, and I am seeking information regarding the Burst Pressure and Proof Test Pressure of LiPo batteries.

Gaston died today, December 3, 2024, from cancer. He was 97. Gaston was recently given the title “Elder Statesman” by the ARISS International team. This honor was given because of his monumental role in the formation and operation of the ARISS team. He wrote our ARISS Terms of Reference and participated in numerous discussions, over the years, on how to run a cohesive, results-oriented international team. His in-depth knowledge of amateur radio rules and regulations, particularly his knowledge of licensing and 3rd party traffic, enabled ARISS to develop an operations plan that could support human spaceflight amateur radio operations across the world. His knowledge of radio telecommunications was respected in Europe and elsewhere, allowing him to give presentations on amateur radio in space to members of the European Parliament. His personality radiated an inviting aura to all. He has been a friend, a leader, and an inspiration to all of us. Gaston began his journey in human spaceflight amateur radio by guiding a group of engaging students in a radio contact at a Belgian Space Camp during the 1992 STS-45 Space Shuttle mission. This contact was with Belgium’s first Astronaut, Dirk Frimout ON1AFD. Gaston coordinated the radio contact preparations and operated the radio station during the contact. Gaston was instrumental in convincing ESA to install L/S band antennas on the Columbus module, prior to launch, to support future operations in Columbus. He worked with Professor Pawel Kabacik from the Wroclaw University to design, build and certify the antennas and led a fundraising campaign to pay for the development, test and certification. With HamTV as the first hardware “customer” of these antennas, Gaston led the HTT, the HamTV Technical Team meetings to prepare the HamTV ground stations for operations and to coordinate the on-board HamTV operations. The L/S antennas have also been employed for two flight experiments: MarconISSta with TU Berlin and the upcoming NAVCOM experiment for ASI/Qascom. Gaston will be sorely missed. But the light of his legacy shines in all of us that he has touched—inside and outside of ARISS. Ad Astra Gaston! (To the Stars, Gaston!) Many times a school may make a last minute decision to do a Livestream or run into a last minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication. You can always check https://live.ariss.org/ to see if a school is Livestreaming. The crossband repeater continues to be active. 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. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-12-05 01:00 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2024-12-04 17:00 UTC. 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. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.

04 Dec '24

* No. 24-87* *Dave Jordan, AA4KN * *ARISS PR* *dave.jordan(a)ariss-usa.org <dave.jordan(a)ariss-usa.org>* *FOR IMMEDIATE RELEASE* *ARISS Contact is Scheduled with Students at * *Publiczna Szkoła Podstawowa im. Walentego Stefańskiego w Bodzechowie, Bodzechów, Poland* December 4, 2024—Amateur Radio on the International Space Station (ARISS) has received schedule confirmation for an ARISS radio contact between an astronaut aboard the International Space Station (ISS) and students at the Publiczna Szkoła Podstawowa im. Walentego Stefańskiego w Bodzechowie, Bodzechów, Poland located in Bodzechów, Poland. 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. This is a small public primary school in Bodzechów in the Świętokrzyskie Province. It serves about 200 students who have been preparing for this ARISS contact by expanding their knowledge in the fields of astronautics and science, covering topics in physics, chemistry and mathematics. Students have also been motivated to learn English through numerous presentations, trips to participating institutions and organizations and thematic competitions. Students took part in workshops at the Copernicus Science Centre in Ostrowiec Świętokrzyski, including one called SOWA. SOWA, which means 'owl' in Polish, is an acronym for the Discovery and Activity Zone, where students developed their creativity and gained knowledge through interactive experiences. They also visited the "Cosmopark" in the Czarnowska Gallery in Kielce - a unique space exhibition, including spacesuits, flight simulators, space plasma and a planetarium. During World Space Week at school, they took part in competitions, such as creating spaceship models and a Space fashion show. An additional attraction for the younger classes was the mobile planetarium "ORBITEK", where they learned about the history of space exploration and Earth's place in the Universe through special projections. Amateur radio activities at the school are supported by members of the Ostrowiecki Amateur Radio Club PZK (SP7POS) who have conducted workshops for students and teachers, presenting various aspects of amateur radio, including communication techniques with the space station. This will be a direct contact via Amateur Radio allowing students to ask their questions of astronaut Sunita Williams, amateur radio call sign KD5PLB. 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 Bodzechów, Poland. Amateur radio operators using call sign SP7POS, will operate the ground station to establish and maintain the ISS connection. The ARISS radio contact is scheduled for December 6, 2024 at 12:49:23 pm CET (Poland) (11:49:23 UTC, 6:49 am EST, 5:49 am CST, 4:49 am MST, 3:49 am PST). The public is invited to watch the live stream at: https://youtube.com/live/1Ch_r219Tvk *_______________________________* As time allows, students will ask these questions: 1. Do you think time passes faster or slower in space? 2. How much electricity does the ISS use each day? 3. Is the spacesuit comfortable? 4. What do you eat in space? 5. Which planet do you think is the most beautiful, apart from the Earth? 6. What do Saturn's rings look like up close? 7. What is life like for NASA astronauts who are staying on the ISS longer than planned? 8. Do you miss your family and friends? 9. Have you always wanted to be an astronaut? 10. What do astronauts do on the ISS? 11. What was your favourite subject in primary school? 12. Do you think humans will one day be able to land on Mars? 13. If you get sick in space, how do you deal with illness? 14. What is your favourite way to spend your free time on the ISS? 15. What is the most challenging part of being an astronaut? 16. What do you think about when you look at the Earth? *About ARISS:* Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the ISS.

Gaston died today, December 3, 2024, from cancer. He was 97. Gaston was recently given the title “Elder Statesman” by the ARISS International team. This honor was given because of his monumental role in the formation and operation of the ARISS team. He wrote our ARISS Terms of Reference and participated in numerous discussions, over the years, on how to run a cohesive, results-oriented international team. His in-depth knowledge of amateur radio rules and regulations, particularly his knowledge of licensing and 3rd party traffic, enabled ARISS to develop an operations plan that could support human spaceflight amateur radio operations across the world. His knowledge of radio telecommunications was respected in Europe and elsewhere, allowing him to give presentations on amateur radio in space to members of the European Parliament. His personality radiated an inviting aura to all. He has been a friend, a leader, and an inspiration to all of us. Gaston began his journey in human spaceflight amateur radio by guiding a group of engaging students in a radio contact at a Belgian Space Camp during the 1992 STS-45 Space Shuttle mission. This contact was with Belgium’s first Astronaut, Dirk Frimout ON1AFD. Gaston coordinated the radio contact preparations and operated the radio station during the contact. Gaston was instrumental in convincing ESA to install L/S band antennas on the Columbus module, prior to launch, to support future operations in Columbus. He worked with Professor Pawel Kabacik from the Wroclaw University to design, build and certify the antennas and led a fundraising campaign to pay for the development, test and certification. With HamTV as the first hardware “customer” of these antennas, Gaston led the HTT, the HamTV Technical Team meetings to prepare the HamTV ground stations for operations and to coordinate the on-board HamTV operations. The L/S antennas have also been employed for two flight experiments: MarconISSta with TU Berlin and the upcoming NAVCOM experiment for ASI/Qascom. Gaston will be sorely missed. But the light of his legacy shines in all of us that he has touched—inside and outside of ARISS. Ad Astra Gaston! (To the Stars, Gaston!) Many times a school may make a last minute decision to do a Livestream or run into a last minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication. You can always check https://live.ariss.org/ to see if a school is Livestreaming. The crossband repeater continues to be active. 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. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-12-04 17:00 UTC.

(***) 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. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates.
