Firefly Delivers New Amateur Satellites to Orbit
The Firefly Alpha FLTA005/NASA ELaNa 43 mission, nicknamed âNoise of
Summer,â 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 AMSATâs 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 Maineâs ground station for further processing.
Amateurs are encouraged to use AMSATâs 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. CatSatâs 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, CatSatâs
antenna will deploy and inflate to a diameter of just over
one-and-a-half feet CatSatâs 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 Earthâs
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-iâs 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 SSTVâs are every 5 minutes.
The working frequencies are as follows:
Downlink 144.175 MHz FT8 Mode:
â Callsign AO4ARI HO60 if the antenna has been deployed
â 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 donât 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 âensureâ 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@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 Ã 230 Ã 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, PAÃDLO, 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 hereâs 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 donât 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 â which are highly guarded for scientific study
only â thereâs 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 âspace bricksâ
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 arenât smooth
like regular LEGO bricks, ESA said the space bricks gave ESAâs space
engineers the flexibility to build and test a variety of structures
using this new material.
âItâs no secret that real-world scientists and engineers sometimes
try out ideas with LEGO bricks,â said Emmet Fletcher, Head of ESAâs
Branding and Partnerships Office. âESAâs 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.â
âNobody 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,â said . ESA Science Officer Aidan Cowley. âIt was
both fun and useful in scientifically understanding the boundaries of
these techniques.â
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 weekâs 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

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). HamTV (2.395 GHz) and SSTV (145.80 MHz) are both stowed.
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.

Upcoming Satellite Operations
NDÃC 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 ⦠NOAAâs 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 weekâs 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 Muskâs 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
ISSâs 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 ISSâs 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) â¦
during a static fire test of the first stage of Chinaâs
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.
