TEVEL Satellites Begin Atmospheric Reentry and Decommissioning
The TEVEL satellite project, featuring a series of CubeSats designed and built by Israeli students, has entered its final phase with the beginning of atmospheric reentry and decommissioning. 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.

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.

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.

Ariane 6 Launches PariSat: Young Engineers Test Heat Dissipation
On July 9, 2024, Europe's newest rocket, the Ariane 6, launched with a range of missions on board, each with unique objectives and dedicated teams. 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.

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.

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.

SpaceX to Develop Enhanced Dragon Spacecraft for ISS Deorbit
SpaceX will develop an enhanced version of its Dragon spacecraft for NASA to deorbit the International Space Station (ISS) at the end of its operational life. 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…>

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…>

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.

Changes to AMSAT-NA TLE Distribution for July 26, 2024
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 satellite has been removed from this week's AMSAT TLE distribution:

Satellite Shorts From All Over
+ ASRTU-1 is a 12U CubeSat mission developed by students from the Harbin Institute of Technology and Bauman State Technical University. 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.

+ SpaceX successfully test-fired the engines on its Super Heavy booster on July 15, 2024, in preparation for the fifth integrated flight test (IFT-5) of its Starship vehicle. 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.

+ The 188,000-pound, 212-foot-tall core stage for the Artemis-2 moon mission has arrived at NASA's Kennedy Space Center (KSC) following a 900-mile journey from Michoud Assembly Facility in New Orleans. 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. (ANS thanks Jeff Foust, SpaceNews<https://spacenews.com/>, for the above information)

------------------------------
AMSAT Mail Alias Service to End August 31, 2024
A long-standing member service, the AMSAT Mail Alias Service is scheduled
to end on August 31, 2024. A mail alias on AMSAT.ORG permitted people to
send an email to members without knowing their actual internet email
address. They just needed to know their amateur radio callsign.
Unfortunately, the unchecked rise in domain name hacking and email account
high-jacking has made it impossible to sustain this service at a
cost-effective level. The number of callsign(a)amsat.org email accounts that
had been hijacked and converted to zombie spam accounts over the years had
led many internet service providers and gateway centers to ban all @
amsat.org email addresses, including those business accounts of AMSAT
officers and officials. The tireless efforts of AMSAT’s all volunteer IT
staff has worked for years to repair much of the damage, but AMSAT still
get complaints from members who are not getting their personal emails, ANS
bulletins or AMSAT-BB posts because of persistent delivery problems.
It has come to the point where the AMSAT volunteer IT staff can no longer
keep up with the maintenance requirements to keep the alias mail list clean
and to work with email gateways to remove blocks. And, after considerable
investigation into alternative paid email services, AMSAT leadership
decided that the money required to keep an email alias system alive would
be better spent on building and flying satellites for its members.
Persons using the Mail Alias Service should begin to migrate to different
email accounts so they do not lose receipt of personal emails, AMSAT News
Service Weekly Bulletins, AMSAT-BB posts, or official messages from AMSAT
itself. Members are especially asked to make sure they are NOT using a
callsign(a)amsat.org as their registered email address in the AMSAT
membership portal. Members can easily change their registered member email
address by logging into the portal and updating their profile.

Tevel Satellites Nearing Re-Entry
The Tevel series of satellites is approaching re-entry, with Tevel-5
already re-entering on July 18th.
The Tevel mission consists of 8 satellites developed by the Herzliya
Science Center in Israel, each carrying an FM transponder. The satellites
were built by 8 schools in different parts of Israel and launched in
January 2022 on the SpaceX Falcon 9 Transporter-3 mission.
A number of other satellites with amateur radio payloads are also
re-entering shortly. A list of satellites approaching re-entry can be found
at http://lu7aa.org/decay.asp

AMSAT-OSCAR 7 in Continuous Sunlight
AMSAT-OSCAR 7, soon to celebrate its 50th birthday on November 15, 2024, is
now in a period of continuous sunlight through May 22, 2027.
While in continuous sunlight, the satellite's internal timer is expected to
switch between the two transponders - Mode A (29 MHz downlink and 145 MHz
uplink) and Mode B (145 MHz downlink and 29 MHz uplink) every 24 hours.
Post reports and check current status on the AMSAT Live OSCAR Satellite
Status Page <https://www.amsat.org/status/>. After a few days in continuous
sunlight, it should be possible to determine the actual or approximate time
the satellite switches.

Changes to AMSAT TLE Distribution for July 19, 2024
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 Thursday evenings around 2300 UTC, or more frequently if
new high interest satellites are launched. More information may be found at
https://www.amsat.org/keplerian-elements-resources/
The following satellites have been removed from this week's AMSAT TLE
distribution:
MESAT1 remains on this distribution. No signals have been detected from any
other amateur spacecraft launched as part of NASA's ELaNa 43 mission.

Grace Papay, K8LG Named 2024 WA6ITF Memorial Amateur Radio Newsline Young Ham of the Year
Grace Papay, K8LG, of Holland, Michigan, has been selected as the 2024 Bill Pasternak WA6ITF Memorial Amateur Radio Newsline Young Ham of the Year. Grace, 18, is the daughter of Doug Papay, K8DP, and Carrie Papay K8CLP.
Grace earned her Technician license in March 2021 and within a year achieved her Extra Class license, passing the test in March 2022.
She is a recent honors graduate of Holland Christian High School in her hometown, where she earned a varsity letter in the Unified Sports program.
Grace credited her father and her grandfather, John Papay, K8YSE, a well-known operator in the ham radio satellite community, for drawing her into the hobby.
“I got involved in amateur radio satellites,” Grace recalls. “I got on the air. And now it has turned into something from honoring my grandfather to a hobby I’m on every day and I love.” With support from her grandfather and father, she earned the DX Century Club certificate for contacts exclusively using satellites.
Grace attended Youth on the Air camps in Cincinnati in 2022 and Ottawa in 2023, where she says she was exposed to a variety of other amateur radio activities including balloon launches, slow-scan television and radio contesting.
She was part of the K3LR IOTA Dave Kalter Memorial Youth DX Adventure in 2023 and was a team member for the J62K St. Lucia DX contest operation in 2024. Grace is active on the HF bands and operates in the ARRL and CQ DX SSB and CW contests, ARRL Sweepstakes and CQ WPX, as well as Youth on the Air events.
For the past few years, Grace has been a regular presenter at the Youth Forum at Dayton Hamvention. She delivered a presentation on youth in contesting at the Contest University Forum at Dayton this year and assisted at the YOTA and AMSAT booths.
She is an active member of the Holland Amateur Radio Club, Grand Rapids Amateur Radio Association, West Chester Amateur Radio Association and the American Radio Relay League.
Grace received the Radio Club of America’s Young Achievers Award in 2023. She had an article on the “Next Generation of Contesters” published in the National Contest Journal (Nov/Dec 2023). A story she co-wrote on YOTA Camp 2022 appeared in the August 2022 edition of CQ magazine.
Grace will be attending Cedarville University in Cedarville, Ohio this fall, where she will study electrical engineering. She says amateur radio played a major role in her choice of a major.
The YHOTY award will be presented to Grace during a ceremony at the Huntsville Hamfest on Saturday, Aug. 17, 2024 at the Von Braun Center in Huntsville, Alabama. Amateur Radio Newsline and Yaesu USA are primary sponsors of the award, along with Heil Sound Ltd. and Radiowavz Antenna Company.
The Young Ham of the Year Award was inaugurated by William Pasternak, WA6ITF, in 1986. Upon his passing in 2015, Bill’s name was added to the award as a memorial to his commitment to recognizing the accomplishments of young people to the Amateur Radio Service.

AMSAT TLE Dissemination Updates
AMSAT with help from its partner New England Sci-Tech prepares a bulletin of orbital elements during the first hour of the UTC day, and posts it to https://www.amsat.org/tle/daily-bulletin.txt as well as "bare" elements without the bulletin header and footer at https://www.amsat.org/tle/dailytle.txt. Other files and URLs with "nasa" and "ftp" in the URL are still maintained to support older software, but suggest organizations protocols that are no longer involved in TLE dissemination. Use of older filenames and URLs is deprecated and AMSAT does not promise to maintain them in perpetuity.
End users and software developers are encouraged to use the URLs above going forward. The files are available via HTTPS (preferred) as well as unencrypted HTTP for legacy software.

Updating Keps in SatPC32 - An Update from DK1TB
Erich Eichmann, DK1TB, SatPC32 author offers this update:
"The SatPC32 Update Keps feature doesn't work with https links for TLE files. That would require changes of the source code and maybe requires a new Delphi version for me. I will care about that but that will at least take time and at present I don't have much time for the hobby.
"But all https websites can be accessed also with http. They are not "secure" sites but that is meaningless with websites that contain Keps. Therefore use http in the aux. file Celestrak.SQF for AMSAT and Celestrak TLE (Two Line Elements) files, as described by Charlie, AJ9N, see below. With that modification the Download Keps function works.
"Also, the https links can be accessed with your browser, of course. Enter the links into the address line of the browser. So, you can download the Keps and save them in the SatPC32 data folder 'Kepler' (see path to that folder in the footline of menu 'Satellites').
"By the way - Meanwhile my website supports also SSL. You can access it with https://www.dk1tb.de and https://www.dk1tb-2.de.
"Also, SatPC32 supports now, besides TLE files, the new formats for Keps files XML, KVN and CSV. Celestrak publishes the Keps files also in these formats. The SatPC32 UpdateKeps feature works with these files also when downloaded from https sites (I don't know why that is different versus the TLE files). Therefore you can use https in Celestrack SQF with these files such as https://celestrak.org/NORAD/elements/gp.php?GROUP=amateur&FORMAT=xml."

The ionosphere stretches from 50 to 400 miles above the planet and marks the boundary between our planet's atmosphere and outer space. While it houses most satellites orbiting the Earth, it's vulnerable to changes in space weather — electromagnetic radiation emitted by the Sun — that can wreak havoc in the zone and mess with communications equipment.
Under some conditions, the layer can become electrically charged. As detected by the Global-scale Observations of the Limb and Disk (GOLD) imaging instrument, plasma bands stretching across the ionosphere can result in formations of unusual X and C shapes.
It's a baffling "alphabet soup," as NASA termed the findings in a news release, that could shed light on how space weather can influence our planet's upper atmosphere and "interfere with radio and GPS signals."
Charged particles can create dense bands or "crests" around the Earth's magnetic equator, while low density pockets caused by the setting Sun can result in "low-density pockets" called 'bubbles," according to NASA.
Scientists believe that larger disturbances such as solar storms or even massive volcanic eruptions can cause multiple crests to merge and form an "X" shape, as previous GOLD observations have shown.
But now, scientists have spotted these same shapes without any such occasion, during what scientists call "quiet time."
"Earlier reports of merging were only during geomagnetically disturbed conditions — it is an unexpected feature during geomagnetic quiet conditions," said University of Colorado research associate Fazlul Laskar, who lead-authored a paper on the discovery earlier this year, in a NASA statement.
Scientists are now wondering if something else could be causing these X shapes to appear.
"The X is odd because it implies that there are far more localized driving factors," said NASA scientist and ionosphere expert Jeffrey Klenzing. "This is expected during the extreme events, but seeing it during ‘quiet time’ suggests that the lower atmosphere activity is significantly driving the ionospheric structure."
Apart from X shapes, some bubbles in the ionosphere can also curve into C shapes, which new observations show can appear in close proximity to each other.
In short, there's a lot still to learn about our planet's magnetically charged, protective shell.
"The fact that we have very different shapes of bubbles this close together tells us that the dynamics of the atmosphere is more complex than we expected," Klenzing added.

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 being prepared for integration aboard the Firefly Alpha (Photo
credit, University of Maine)*
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.
*Artist’s rendering of CatSat with 10 GHz balloon antenna deployed.
(University of Arizona)*
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+transmi…
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 LoTW-help(a)arrl.org.
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 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/…
The LEGO website has additional details at
https://www.lego.com/en-us/aboutus/news/2024/june/lego-bricks-scientists-bu…
Hopefully the lunar LEGOs will inspire both children and adults about space
and to encourage them to build their own LEGO Moon bases.

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

AMSAT Ambassador Clint Bradford, K6LCS, says,
“Think a 75-minute presentation on “working the easy satellites” would be
appropriate for your club or event? Let me know by emailing me at
k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!”
Clint has NEVER given the exact same show twice: EACH of the 150+
presentations so far has been customized/tailored to their audiences.

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 <https://www.amsat.org/ans-182-amsat-news-service-weekly-bulletins/>
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.
