Held each year close to the date of the Apollo 11 moon landing, the event features hands-on science exhibits and activities for all ages. Moon Day runs from 10:00 a.m. to 4:00 p.m. CDT, with setup beginning at 8:00 a.m. CDT. AMSAT will once again be represented at the event by AMSAT Ambassador Thomas Schuessler, N5HYP, along with several North Texas satellite enthusiasts. They will engage with the public ? including many young people ? on topics such as satellite orbits, the International Space Station, and amateur radio in space. Exhibits will include the AMSAT Fox CubeSat engineering model and the CubeSat Simulator, and the team hopes to demonstrate a few live satellite passes during the day. Tom is seeking additional AMSAT volunteers from the North Texas area to help staff the exhibit table. The AMSAT booth will be located next to the Dallas Amateur Radio Club exhibit, providing opportunities for great conversations with fellow hams as well as curious families. Volunteers receive free museum admission and lunch. Anyone interested in helping for part or the entire day is encouraged to email Tom at n5hyp [at] arrl [dot] net. *Col. Carl E.

So what’s a French astronaut do to when faced with the prospect of spending months aboard the International Space Station eating freeze-dried food straight from the packaging? Recruit a Michelin-starred chef to reimagine French classics like foie gras and lobster bisque was the answer for Sophie Adenot, KJ5LTN, who is due to undertake her first space mission in 2026. *Chef Anne-Sophie Pic and astronaut Sophie Adenot, KJ5LTN, at a tasting in Paris. (Photo: Groupe Pic and ESA)* The meals designed by Anne-Sophie Pic will make up the “bonus food” taken to the ISS during Adenot’s εpsilon mission, the European Space Agency said in a statement Tuesday, July 1. Food in space is typically freeze-dried and comes in plastic packaging from a list of preapproved items, the ESA said. Fruit and vegetables are a rare luxury that are available only when a spacecraft arrives with supplies. Astronauts, however, are able to have specially catered “bonus food” that makes up about 10 percent of what they eat. This is usually developed in partnership with a chef, and astronauts say it boosts mental well-being, adds variety and helps them bond with fellow crew members when shared in orbit, according to the ESA.

LoTW is a web-accessed database and repository that enables radio amateurs to submit electronic logs for amateur radio contacts (QSOs) and for confirmation (QSLs). Users can view submitted QSOs and resulting QSLs online. Radio amateurs can use LoTW to track their progress toward achievements and awards, such as Worked All States, DXCC, VUCC. It is also used to verify AMSAT awards such as Gridmaster. It is used by the vast majority of satellite operators. ARRL is soliciting donations through the ARRL website to support the maintenance and expansion of LoTW. (ANS thanks ARRL for the above information.) + *AMSAT South Africa* (AMSAT SA) has announced that the 2025 Space Symposium will be held on Saturday 2 August 2025 from 08:00 UTC ? 14:00 UTC and has issued a call for papers. The theme of the symposium is “Embracing 68 years of space science and innovation in Amateur Radio.” Papers are invited covering all aspects of space science and communication impacting and enhancing the Amateur Radio experience, from the technical to operational aspects. Presentations are typically 30 minutes a with a 10-minute Q&A. Send proposals in MS Word to admin [at] amsatsa.org.za by 7 July 2025. To enable as widest as possible audience to participate, this symposium will be held online on the Webex platform. Members of all AMSAT organisations and national societies may attend free upon registration, which open on 9 July 2025. Email admin [at] amsatsa.org.za for details. (ANS thanks AMSAT SA for the above information.) + *SpaceX* launched its 500th Falcon 9 rocket to date with an overnight Starlink flight on Wednesday, July 2. The first stage booster used on the mission also flew for a record-setting 29th time. The mission, dubbed Starlink 10-25, lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 0628 UTC. A little more than eight minutes after liftoff, the booster landed on the droneship, ‘A Shortfall of Gravitas,’ completing the 472nd booster landing to date. (ANS thanks Spaceflight Now for the above information.) + *MethaneSAT*, the Environmental Defense Fund (EDF) methane-tracking satellite backed by the Bezos Earth Fund, is lost in space. Its ground team lost contact with the spacecraft on June 20 but tried to reestablish a connection until it learned in the morning of July 1 that MethaneSAT had lost power altogether. The team believes that the satellite is likely not recoverable. MethaneSAT collected data on methane emissions that have previously been untrackable in an effort to combat climate change. Methane is the second largest contributor to global warming after carbon dioxide, with agriculture, fossil fuels and waste decomposition being the largest sources. (ANS thanks Engadget for the above information.) + EUMETSAT’s *Meteosat-12* satellite, formerly Meteosat Third Generation (MTG) Imager 1, has now taken over from Meteosat-10 to deliver Europe’s prime weather data service from GEO. Meteosat-12 is the first imaging satellite in the MTG program and now moves into its key position above the equator at 0° longitude, directly over the Gulf of Guinea. Meteosat-12 is now the main source of near-real-time geostationary satellite data for Europe, Africa and the surrounding oceans. (ANS thanks satnews for the above information.) + A newly discovered *interstellar object* is only the third such interloper to be observed in our solar system. The object ? provisionally known as A11pl3Z ? is not expected to pose an impact risk to Earth, but gained attention on Tuesday, July 1, when it was spotted by telescopes for NASA’s early warning system for asteroid impacts. Speeding through our solar system at about 245,000 kilometers per hour relative to the sun, it is currently located just inside the orbit of Jupiter, 528 million kilometers from Earth. It’s uncertain at this time if the object ? which will get a new name when it is approved and published by the Minor Planet Center ? is a comet or asteroid, but the observations so far have helped track the object’s journey, indicating it likely came from outside of the solar system from a thin galactic disk.

The theme will be the Apollo Soyuz mission and STS-51F which pioneered SSTV on Shuttles. [cid:image003.jpg ＠ 01DBF322.35E884B0] This series of 12 images will be transmitted from the ISS on 145.800 MHz using PD120 encoding. Software needed to decode the pictures is free and is available for PC's, Mac's, Android smartphones, and iPhones. Search "SSTV software" on Google and your phone's app store for a variety of options. Transmissions from the ISS are powerful enough so images can be received with a handheld radio and its stock rubber duck antenna, albeit quite noisy. The addition of a simple homemade 3-element beam to the handheld can produce in pixel perfect images. Persons who are not familiar with SSTV operations can visit https://amsat-uk.org/beginners/iss-sstv/. You are invited to upload decoded images in the ARISS gallery, area “ARISS Series 28 Apollo Soyuz and STS-51F” at: https://ariss-usa.org/ARISS_SSTV/. Once you’ve submitted your pictures, just click on the dedicated button to apply for the official ARISS SSTV award. Transmissions will begin on Monday, July 14 at 09:15 UTC (05:15 AM Eastern time). Transmissions will cease on Sunday, July 20 at 18:00 UTC (2:00 PM Eastern time).

Rich detailed the software defined radio (SDR) module while Bill explained how the SDR communicates with other systems on the upcoming GOLF satellites. [cid:image016.png ＠ 01DBF322.35E884B0] Rich explained, “The diagram above is a block diagram of the GOLF-TEE 3U CubeSat. The purple rectangle located in the middle of the diagram represents a (SDR). The Fox series of satellites before had transponders. Some were FM transponders. They acted like a repeater up in the sky. A single FM channel up with a single FM channel down. Other Fox satellites had linear transponders with wide bandwidths for several SSB or CW signals. Whatever you sent up to the satellite, either on 2 meters or 440, would come down on the other band. “You could communicate with people that way, operate either FM or linear transponder, but that's all you could do with a transponder. On the other hand, the SDR allows us to do much more interesting things. Instead of the radio being permanently built into the hardware like it was in the Fox series, with an SDR it’s all done in software. We don't have to change the hardware to implement different modes like SSTV or any of the voice, data or image operations we want to try. With an SDR we can do it in software. It's much easier much quicker to do. “The SDR communicates with the RF matrix, represented by the light gray rectangle to the right of the SDR. The SDR communicates and is controlled by other circuits in the satellite through the Controller Area Network (CAN) bus shown to the left of the SDR. That control bus is used to activate and deactivate the radio system as well as command it to perform a variety of operations.” Specifically the SDR for the first GOLF satellites is the Ettus Research™ E310 Universal Software Radio Peripheral (USRP™). Rich explained, “The Ettus 310 SDR has two receive and two transmit antenna connections, which gives us a lot of flexibility in terms of what we want to do. For example, we can create cross-band transponders with it. We will use the radio at 5 GHz and 10 GHz, but it can't do 10 GHz natively. We need to implement some RF hardware externally to increase the original frequency range to 10 GHz. “The Ettus runs on a Linux operating system so we will use GNU Radio software to program radio functions. So, if we want to have the radio operate as a transponder, for Morse code, telemetry, SSTV, or whatever, we can do it can through programming.” It is a free and open-source software development toolkit that provides signal processing blocks to implement software radios. Gopstein remarked, “GNU Radio makes programming easier! The talent and skills of AMSAT engineers are a precious resource. The GNU building block approach saves time while elevating consistency, quality and production rates for the benefit of all AMSAT satellite end users. “We’re using GNU Radio to support radio necessities such as the spacecraft transponder, telemetry and other modes of data transmission for the GOLF satellites. These are just a portion of the functions we're capable of using. “Because the Ettus E310 SDR connects to the RF matrix, various antennas on the satellite can be connected to the SDR. As I said before, the output from the SDR will have a 10 GHz frequency converter and we will also have a solid-state power amplifier. That combination will increase frequency and output power for transmission at 10 GHz then sending the RF to an X band patch antenna.” “One element of RF operation that we're definitely going to try with the SDR is a 1 megabits per second (Mbps) data transmission. Another exciting experiment with the SDR could be ‘five-and-dime’ 5GHz/10GHz microwave radio transponder. On future missions, we expect to use the SDR to try all sorts of other functions with the SDR, yet to be determined,” Rich concluded. [cid:image017.png ＠ 01DBF322.35E884B0] Next, Bill Schell, W2WZ went on to say, “This block diagram is a detailed look at part of the original diagram. It shows the Ettus E310 SDR connected to the main control processor of GOLF-TEE, the RT-IHU (Radiation Tolerant Internal Housekeeping Unit). The two are connected over the CAN bus, over which messages flow in each direction.” “The RT-IHU control software communicates with a python application running on the E310 called ‘SDR Server’. This application receives request messages from the RT-IHU to execute various SDR related actions. It also sends E-310 related status and telemetry information back to the RT-IHU”, Bill added. According to Bill, “One of the most important actions the RT-IHU requests through SDR server is to start and stop GNU radio flows on the E-310. These flows are the software that implement the radio functions of the SDR. A flow might implement a transponder, the transmission of a periodic morse code ID, or the transmission of a data file to a ground station. Flows are created from building blocks in the GNU radio user interface. Common types of blocks include signal sources, filters, modulators, demodulators, FFT’s, math operations, etc. Blocks are combined to implement a flow which accomplishes a particular radio or signal processing task.” “Other actions the SDR server performs are the sending of IMU and temperature data to the RT-IHU, receiving a file for later transmission (by a flow), shutdown, and other housekeeping functions”, Bill concluded.

Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. 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 distributions.

The downlink frequency on which to listen is 145.800 MHz worldwide. [ARISS News] There are no scheduled contacts at this time. 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 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. 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] ________________________________ AMSAT Ambassador Activities AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.

A Q-Band receiver was mounted on Chilbolton Observatory’s large 25m dish. The team at the observatory used this radar tracking capability to monitor the state of the satellite and its orbit during each pass. The team established a stable link with a collocated Ka-Band uplink antenna to the Telesat LEO 3 satellite. The Telesat LEO 3 satellite also provided frequency up-conversion to Q-Band, amplification and retransmission to ground. The Telesat satellite station transmitted a DVBs signal.
