* 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. In the United States, sponsors are the American Radio Relay League (ARRL), Amateur Radio Digital Communications (ARDC), Radio Amateur Satellite Corporation (AMSAT), NASA’s Space Communications and Navigation program (SCaN) and the ISS National Lab—Space Station Explorers. The primary goal of ARISS is to promote exploration of science, technology, engineering, the arts, and mathematics topics.

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.

Woodland Middle School opened in the summer of 2024, is part of Dorchester School District 4, and was created by merging two schools, Harleyville-Ridgeville Middle and St. George Middle. This consolidation enables Woodland Middle School to optimize resources and provide students with expanded access to modern technology, academic programs, and extracurricular activities. This unified approach allows students to explore a wider curriculum, gain exposure to diverse fields, and develop essential skills for high school and beyond, all within a single, state-of-the-art facility. Woodland Middle School participates in the district’s ROVER program, an initiative that brings mobile STEM learning labs directly to students. Through hands-on activities and real-world applications, the ROVER program expands students’ learning opportunities in science, technology, engineering, and math. This ARISS contact is being supported by members of the Trident Amateur Radio Club (N4EE). This will be a direct contact via Amateur Radio allowing students to ask their questions of astronaut Nick Hague, amateur radio call sign KG5TMV. 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 Columbia, SC. Amateur radio operators using call sign N4EE, will operate the ground station to establish and maintain the ISS connection. The ARISS radio contact is scheduled for December 2, 2024 at 11:22:26 am EST (SC, USA) (16:22:26 UTC, 10:22 am CST, 9:22 am MST, 8:22 am PST). *_______________________________* As time allows, students will ask these questions: 1.

In thinking about where this spacecraft sits in electronic history, it is all too easy to forget that it was designed at least three years before the appearance of the first 8-bit microprocessor. The notion of packet communications was still nearly 10 years into the future. The team wanted to demonstrate that they could store data at-will on a spacecraft in transit across the sky and then download it at another location. They wanted to demonstrate non-real-time digital communications to themselves and to the world. Jan King, W3GEY, AMSAT OSCAR-7 Project Manager explains, “Thinking in retrospect, that experiment wasn’t the best it could have been. However, it was simple and it proved our resolve. The entry in 1972 on AO-6 and, then again, in 1974 on-board AO-7 was a demonstration experiment we called CodeStore. And, it did lead to far more ambitious packetized, store-and-forward data satellites in our future. “It probably wasn’t the best choice at the time, but we chose the command frequency for the uplink. This meant we didn’t have to implement yet another receiver. However, this made the experiment far less accessible to hams than it could have. AMSAT did not want to share the knowledge of the command frequency and codes with anyone who didn’t have a need to know them. Thus, CodeStore was not an experiment that was shared with everyone as were the communications transponders. It could realistically only be used by authorized command stations. We had hoped for a universal store-and-forward demonstration, but what was in fact created was a broadcast tool and in that regard CodeStore was very successful.” CodeStore was the brainchild of and was designed and fabricated by John Goode, W5CAY. In one small module, he housed an AFSK decoding system, which allowed uplink data to be clocked into a “long” shift register containing 896 bits. This was done with the memory IC's of the day. What one could manage then was 14 IC's each containing 64 bits of serial data storage. The contents of the shift register was sequentially downlinked first-in-first-out (FIFO) to the selected beacon when CodeStore was commanded to the RUN mode. This number of bits is divisible by 8 so one might have expected that a downlinked message of 112 8-bit words. No, this was 1974 so Morse Code messages were downlinked. The idea was more individuals can copy a broadcast message if they don’t need specialized decoding equipment. King adds, “No one can deny that we could have made a better go of it if the notion of a remote terminal digital communications goal had remained pure. It did not.” “Ultimately, its highest value was discovered to be to store the spacecraft’s NORAD TLEs as well as any critical AO-7 operating schedule modifications, which might be of importance to the users. CodeStore was already available for use on AO-6. So, users were already expecting this feature, which appeared regularly on the beacons.” While CodeStore was used on both AO-6 and AO-7 to demonstrate non-real-time communications via satellite, it was never used by independent remotely located stations to demonstrate two-way communications in that way. The memory facilities required on-board and the lack of any firmware that even approached the capabilities of a file handling system did not exist in 1972-74. That would have to wait for another day when, once again, four AMSAT spacecraft in a small constellation would demonstrate a proper store-and-forward packet handling system. That was to occur in 1990. CodeStore went into service as a broadcast device allowing users to receive, in Morse Code, the latest, (then) NORAD TLEs. CodeStore was a complete success. It saved command stations a tremendous amount of work, avoiding the need for a global network of operators who would otherwise be needed to relay the same data.

And the 2024 AMSAT President’s Club Coins Are Gone! Help Support GOLF and Fox Plus [cid:image001.jpg@01DB4320.F10F2E40] Join the AMSAT President's Club today and help Keep Amateur Radio in Space! https://www.amsat.org/join-the-amsat-presidents-club/ ________________________________ Japan Launches World's First Wooden Satellite to Test Timber in Space Japanese researchers launched the world’s first wooden satellite, LignoSat, into space, marking an ambitious step toward exploring the viability of timber for lunar and Martian construction. This pioneering satellite, developed collaboratively by Kyoto University and Sumitomo Forestry, was sent to the International Space Station aboard a SpaceX mission from NASA’s Kennedy Space Center on November 4, 2024. Once at the ISS, LignoSat will be released into orbit approximately 400 kilometers (250 miles) above Earth. [cid:image002.jpg@01DB4320.F10F2E40] LignoSat, a 1U-sized CubeSat, carries an Amateur Radio mission that will extract callsigns from the FM packet data signals uplinked, and respond to them by using the CW downlink with their call signs. An educational mission is to educate students to learn about the characteristics of the satellite by acquiring its housekeeping data such as the internal temperature, the strain of the wooden structure, and the Earth’s magnetic field and calculating the rotational direction and rate of the satellite as well as observing the effect of the space environment on the wooden structure. The satellite, whose name derives from the Latin word for "wood," is a compact, palm-sized structure. LignoSat’s mission is to demonstrate the potential of wood as a sustainable and durable material for space exploration. Takao Doi, a former astronaut and a current researcher at Kyoto University, expressed that using timber could pave the way for constructing habitats that support human life and work in space indefinitely. “With timber, a material we can produce by ourselves, we will be able to build houses, live, and work in space forever,” Doi said. Doi’s team is working under a 50-year vision of building timber structures on the Moon and Mars, planting the seeds for future space-based infrastructure. The researchers opted for Honoki, a type of magnolia tree native to Japan traditionally used for sword sheaths, after conducting a 10-month experiment on the ISS. Honoki proved its resilience, leading to its selection as the core material for LignoSat. The satellite was constructed using a traditional Japanese craft technique without screws or glue, showcasing innovation steeped in heritage. One of LignoSat’s key roles in its six-month orbit will be to measure the endurance of wood against extreme space temperatures, which oscillate from -100 to 100 degrees Celsius (-148 to 212 degrees Fahrenheit) every 45 minutes as the satellite shifts from sunlight to darkness. The onboard sensors will also monitor how well wood mitigates space radiation’s impact on semiconductors, information that could be pivotal for designing data centers and other space-based structures. Kenji Kariya of Sumitomo Forestry emphasized the cutting-edge nature of this research, noting that despite appearing old-fashioned, wood could be integral to future space technology. The environmental benefits of using wood in space are significant. Unlike conventional metal satellites that produce polluting aluminum oxide particles upon re-entry, wooden satellites would disintegrate more cleanly in Earth’s atmosphere. “A wooden satellite burns up with much less pollution compared to metal ones,” Doi stated. This feature could be an advantage as the space industry grapples with sustainability and the proliferation of space debris. [cid:image003.jpg@01DB4320.F10F2E40] The team behind LignoSat is optimistic that their experiment could spur wider adoption of timber in space exploration. Doi even hinted at the potential for future partnerships, saying, “If we can prove our first wooden satellite works, we want to pitch it to Elon Musk’s SpaceX.” The successful deployment of LignoSat could mark the beginning of a new era where traditional materials meet advanced space technology, reinvigorating the timber industry and pushing the boundaries of sustainable innovation in space exploration. A downlink on 435.820 MHz has been coordinated for CW, 4k8 GMSK AX25 telemetry and FM.

When engineers commanded Voyager 1 to switch on one of its heaters to give the instruments a gentle thermal massage, a safety feature was tripped because of low power levels. It automatically switched off non-essential systems. The fault protection system took it upon itself to switch off the main X-band transmitter and activate the lower-power S-band transmitter instead. Because of the great distance between Voyager 1 and Earth, however, transmissions on the S-band antenna could not be heard by NASA's Deep Space Network, meaning that Voyager 1 had effectively fallen silent. NASA engineers were able to resolve the problem early in November, and X-band communication resumed on Nov. 18, with the spacecraft once again returning data from its four remaining instruments.
