Firefly Delivers New Amateur Satellites to Orbit
The Firefly Alpha FLTA005/NASA ELaNa 43 mission, nicknamed “Noise of Summer,” launched successfully at 04:04 UTC on July 4 (Wednesday evening, July 3 in the U.S.) and deployed eight new cube satellites to Low Earth Orbit (LEO). Five of these cubesats carry amateur radio equipment.
The cubesats were placed into a sun-synchronous Earth orbit, meaning that all locations on earth will see high-elevation passes roughly between 8:00 and 10:00 a.m. and between 8:00 and 10:00 p.m. local time daily, with lower elevation passes earlier and later.
Among the newly-deployed satellites, the one of greatest interest to the amateur radio community is MESAT1. Built by the University of Maine, in cooperation with AMSAT, this satellite carries a 30 kHz wide V/U Transponder plus a 1k2 BPSK telemetry downlink. Telemetry downlink 435.800 MHz with transponder downlink 435.810-435.840 MHz, and transponder uplink 145.910-145.940 MHz. Amateurs are encouraged to use AMSAT’s FoxTelem software to collect telemetry.

MESAT1 involves three missions designed by high school students in Maine. The science payloads are climate focused and include ALBEDO, IMAGER, and HAB. These will identify urban heat islands, determine concentration of phytoplankton in water bodies, and help predict harmful algal blooms. Four multispectral cameras on board will relay the data down to University of Maine’s ground station for further processing. Amateurs are encouraged to use AMSAT’s FoxTelem software to collect telemetry and assist in these science projects.
Also deployed was CatSat, a technology demonstration of an inflatable antenna for high-speed communications, built by the University of Arizona. CatSat’s deployable antenna consists of a Mylar balloon. The front half of the balloon is transparent, allowing microwaves to pass through. The back half of the balloon is aluminized, creating a reflecting antenna. After reaching low Earth orbit, CatSat’s antenna will deploy and inflate to a diameter of just over one-and-a-half feet CatSat’s demonstration will be to transmit high-definition Earth photos to 10 GHz, X-band ground stations at ~50 megabits per second.

In addition to images, data about the structure of the Earth’s ionosphere will be gathered by listening-in to thousands of beacons from ground-based ham radio stations. CatSat will relay WSPR and FT8 signals from HF. Downlinks on 437.185 MHz and 10470.00 MHz.
Other satellites with IARU-coordinated amateur frequency downlinks include:
Serenity, which uses a 4k8 FM with AX25 downlink on 437.100 MHz. Serenity was built by Teachers in Space, Inc., a 501(c)(3) nonprofit educational organization in North America that stimulates student interest in science, technology, engineering, and mathematics (STEM). They provide teachers with real space science experiences, space flight opportunities, and industry connections.
KUbeSat-1, revives small satellite research at the University of Kansas and starts a new KUbeSat program that will offer space access to student research. The main payload on KUbeSat-1 is the Primary Cosmic Ray Detector which will use a new method to measure the energy and species of primary cosmic rays hitting the Earth. The secondary payload is the High-Altitude Calibration, (HiCalK) that builds on decades of research surrounding Very High Frequency signals generated by cosmic ray interactions with the atmosphere. UHF downlink using 9k6 GMSK. A downlink on 437.085 MHz.
SOC-i (Satellite for Optimal Control and Imaging) is a technology demonstration mission of attitude control technology and a camera that serves as an instrument to demonstrate SOC-i’s pointing abilities. Developed at the University of Washington, SOC-i has a UHF downlink using 4k8 GMSK. downlink 437.125 MHz.

Ariane 6 Maiden Flight With GENESIS-A Module
The maiden flight of the new European launcher, Ariane 6, is scheduled for July 9, 2024, with a launch window of 3:00 p.m. to 7:00 p.m. local time from the European spaceport in French Guiana (July 9 20:00h to July 10 00:00h CEST). Among many other payloads, it carries our (inside YPSAT) GENESIS-A module, attached to the second stage of the launcher. The module will transmit FT8 and live SSTV images in Robot 36 format.
FT8 transmissions are made every 16 seconds, while SSTV’s are every 5 minutes.
The working frequencies are as follows:
Downlink 144.175 MHz FT8 Mode:
– Callsign AO4ARI HO60 if the antenna has been deployed
– Callsign AO4ARI HO61 if the antenna has not been deployed
Downlink 144.550 MHz SSTV Robot 36 mode with live image and Hades text
A carrier with a frequency of 144.550 MHz (same frequency as SSTV) is left between FT8 tones.
This information is compiled in PDF in the following document on our web:
https://www.amsat-ea.org/app/download/13458580/AMSAT+EA+-+GENESIS-A+transmissions+description.pdf
The only thing ESA has given us is the trajectory over the ground while flying over Europe, but we don’t have TLEs or anything that we can semi-automate. It is available on our website:
https://www.amsat-ea.org/s/cc_images/cache_19006006.jpg?t=1720182961
It will be very difficult to receive it but we thank you all if you try and if you spread this information to have all possible operators tuned into FT-8 that day. The module will fall into the sea with the second stage after a few hours.

Logbook of The World Returns To Service
Effective 12:00pm ET / 16:00 UTC on July 1, Logbook of The World® (LoTW®) has been to service.
As work progressed on the network, some users encountered LoTW opening briefly during which some 6600 logs were uploaded. The logs were not processed until this weekend as we tested that the interfaces to LoTW were functioning properly.
We are taking steps to help manage what will likely be a huge influx of logs. We are requesting that if you have large uploads, perhaps from contests or from a DXpedition, please wait a week or two before uploading to give LoTW a chance to catch up. We have also implemented a process to reject logs with excessive duplicates. Please do not upload your entire log to “ensure” your contacts are in LoTW as they will be rejected. Lastly, please do not call ARRL Headquarters to report issues you are having with LoTW. You can contact support at [email protected].
Through the end of the year, you may experience planned times when LoTW will be unavailable. We have been using this time to evaluate operational and infrastructure improvements we would like to make to LoTW. Those times will be announced.
We appreciate your patience as we worked through the challenges keeping LoTW from returning to service. We know the importance of LoTW to our members, and to the tens of thousands of LoTW users who are not ARRL members. LoTW, just behind QST, is our second most popular ARRL benefit.

LUSAT, Dead or Alive?
LO-19, co-ordinated by AMSAT Argentina, the LUSAT (named after the LU amateur designation for Argentina) microsatellite was launched on the first ARIANE ASAP flight V35 with SPOT 2, on the 22 January 1990 (01:35:27 GMT) into an 780 km sun-synchronous, 98 degree inclined orbit.
It carried a Digital Store and Forward packet communications transponder similar to AO-16. Downlink was AX.25 at 437.125 MHz SSB 1200 bps RC-BPSK. It is box shaped with dimensions of 213 × 230 × 230 mm, with four solar panels and weighs 13.76 kg.
Long past its expected useful life, in recent years LUSAT has only been transmitting an unmodulated carrier signal.
On June 29, Gustavo Carpignano, LW2DTZ, reported that recent observers had failed to detect the carrier. Gustavo declared LO-19 dead.
However, on July 1, Nico Janssen, PAØDLO, reported receiving the carrier, but at a signal strength much weaker than over previous years. Nico suggested that, perhaps, the onboard power amplifier has failed.
Well-equipped ground stations may wish to give a listen to test what they can hear.

LEGO Bricks Printed out of Space Dust
There have been many proposals for building structures on the Moon out of lunar regolith. But here’s an idea sure to resonate with creators, mechanical tinkerers, model builders and the kid inside us all.
What about using actual LEGO bricks?
Researchers ground up a 4.5-billion-year-old meteorite and used the dust to 3D print LEGO-style space bricks. They actually click together like the plastic variety, with so far only one downside: they only come in one color, grey.
Universe Today
Want to see some of these lunar LEGOs? LEGO will showcase the space bricks at some of its stores.
Creating building materials on the Moon or Mars from the material on hand means construction materials don’t have to be transported from Earth. This would be a huge savings in launch costs because less weight would have to be boosted from Earth.
A group of scientists from ESA (European Space Agency) were inspired by LEGO bricks, and with the advances in 3D printing, had the idea to print space bricks and test how they would work for construction.
The only problem was that except for the Moon rocks brought back by the Apollo astronauts – which are highly guarded for scientific study only — there’s not any lunar regolith available on Earth to experiment with.
But meteorite dust is a close cousin to lunar regolith. The ESA team was able to get a meteorite that was discovered in Northwest Africa in 2000 and is about 4.5 billion years old. It is made of metal grains and chondrules, similar to Moon dust.
Inspired by LEGO, ESA scientists have used dust from a meteorite to 3D-print LEGO-style ‘space bricks’
to test out construction ideas for a future Moon base. Credit: The LEGO Group
They mixed the meteorite dust with a some other things, like a polymer called polylactide and regolith simulant and 3D printed bricks that mimic and behave just like LEGO bricks. While they aren’t smooth like regular LEGO bricks, ESA said the space bricks gave ESA’s space engineers the flexibility to build and test a variety of structures using this new material.
“It’s no secret that real-world scientists and engineers sometimes try out ideas with LEGO bricks,” said Emmet Fletcher, Head of ESA’s Branding and Partnerships Office. “ESA’s space bricks are a great way to inspire young people and show them how play and the power of the imagination have an important role in space science, too.”
“Nobody has built a structure on the Moon, so it was great to have the flexibility to try out all kinds of designs and building techniques with our space bricks,” said . ESA Science Officer Aidan Cowley. “It was both fun and useful in scientifically understanding the boundaries of these techniques.”
For a list of where the lunar LEGOs will be on display worldwide, see https://www.universetoday.com/167675/lego-bricks-printed-out-of-space-dust/#more-167675
The LEGO website has additional details at https://www.lego.com/en-us/aboutus/news/2024/june/lego-bricks-scientists-build-astronaut-shelters-on-the-moon
Hopefully the lunar LEGOs will inspire both children and adults about space and to encourage them to build their own LEGO Moon bases.

Changes to AMSAT-NA TLE Distribution for July 5
Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. 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/.
The following satellites from last week’s Firefly Alpha FLTA005/NASA ELaNa 43 launch have been added. They are listed as OBJECT A-H, with the exception of object G which is likely MESAT1. As is the case with most cubesat launches, it will take a while to figure out which object is which.
OBJECT A 60203
OBJECT B 60204
OBJECT C 60205
OBJECT D 60206
OBJECT E 60207
OBJECT F 60208
MESAT1 60209
OBJECT H 60210
OBJECT J 60211
OBJECT K 60212

Upcoming Satellite Operations
NDØC and family will be on another family camping vacation from 24 June thru 7 July, this time through Wisconsin to Michigan and back thru Illinois and Iowa. No super rare grids but several that may be needed by many. The grids and passes will depend on where/when we happen to be while on the road or camping. This will be all LEO sats: FM & SSB. As always, they will try for EU passes on RS-44 when possible. Randy is looking forward to pushing past the 100 grids-roved milestone.
A growing number of satellite rovers are currently engaged in sharing their grid square activations on https://hams.at. By visiting the website, you gain easy access to comprehensive information about the operators responsible for activating specific grid squares. Additionally, you have the ability to assess the match score between yourself and a particular rover for a given pass, while also being able to identify the upcoming satellite passes that are accessible from your location.

Satellite Shorts From All Over
+ What GOES up … NOAA’s latest Geostationary Operational Environmental Satellite, GOES-U, launched on the first Falcon Heavy of the year on June 25 from Launch Complex 39A at Kennedy Space Center. The mission, the last of the GOES-R series of geostationary weather satellites, continuously monitors weather systems over the Western Hemisphere. Assuming that next week’s planned burn to lift the satellite to geosynchronous orbit is successful, this satellite will be re-designated as GOES-19 and will, in coming months, take over the GOES-East duties from the aging GOES-16. (See ANS 182 last week for more details.)
+ Musk come down … Elon Musk’s SpaceX has won a contract valued at up to $843 million to build a vehicle capable of safely deorbiting the International Space Station once the station is decommissioned in 2030. While many people have suggested raising the ISS’s orbit and turning it into a museum, the amount of fuel needed to move the approximately 420-ton station to a high enough orbit to remain stable for long durations is prohibitive.
+ Blow up … Russian Resurs-P1, an almost-six-ton defunct Earth observation satellite that stopped orbit maintenance in 2017 but continued operations until 2022, unexpectedly exploded last week into hundreds of fragments. Expected to reenter later this year, Resurs-P1 was orbiting at ~350 km, close enough to the ISS’s orbital altitude that the event forced ISS astronauts into shelter for an hour while debris was tracked.
+ Or go up, come down, and blow up (unexpectedly) … during a static fire test of the first stage of China’s close-to-finished Tianlong-3 rocket, the hold-down hardware failed to do its singular job: hold down the rocket. Moments after ignition, the rocket shot 1.5 km into the sky above the city of Gongyi, China. With no guidance system, gravity took over, resulting in a massive fireball on impact. Very fortunately, there were no casualties as the rocket mostly went straight up and straight back down.
