Spain's URESAT-1 Collaborative Satellite Launches on SpaceX Transporter-8
The URESAT-1 satellite, also known as HADES-B according to its ITU
designation, successfully launched into space as part of the SpaceX
Transporter-8 mission from Vandenberg AFB on Monday, June 12. The satellite
is a joint effort between AMSAT-EA, URE (the Spanish equivalent of ARRL),
private companies, and universities.
The URESAT-1 satellite, contained within the D-Orbit ION Orbital Transfer
Vehicle (OTV), was not deployed directly from the Falcon-9 rocket. Instead,
approximately one hour and twenty minutes after launch, the Falcon-9 released
the OTV, which will orbit the Earth for several days before deploying
URESAT-1, along with other satellites.
One of the primary objectives of URESAT-1 is to serve as an FM voice and FSK
data repeater. Equipped with a Slow Scan Television (SSTV) camera, the
satellite will transmit live images as well as stored images at regular
intervals. It also features a chess game, enabling players on Earth to engage
in a game against the satellite. Periodically, the satellite will transmit
updates on the state of the game, including the chess board, the last
movement made, and whether the next move belongs to the players or the
satellite.
The specified frequencies for communication with URESAT-1 are as follows: for
uplink transmissions, 145.975 MHz or 145.925 MHz (auxiliary frequency) using
FM voice without subtone, FSK 50 bps, AFSK, AX.25, APRS 1200/2400 bps. For
downlink transmissions, the frequency is set at 436.888 MHz, and modes
include FM voice, CW, FSK 50 bps telemetry, SSTV Robot 36, and a voice beacon
with the callsign AO4URE.
To provide further information regarding URESAT-1's transmissions, the
AMSAT-EA organization has made available a comprehensive document that can be
accessed at the following link:
https://www.amsat-ea.org/app/download/13366685/AMSAT+EA+-+URESAT-1+Transmissions+description.pdf
For those interested in decoding the telemetry, a Linux x86/ARM decoder is
available for download at the following link:
https://www.amsat-ea.org/app/download/13395017/URESAT-1_telemetry_decoder_Linux_X86_ARM_v1.0.zip
A sample file containing the audio of a telemetry file can be found here:
https://www.amsat-ea.org/app/download/13398144/URESAT-1_sample_FSK_telemetry-chessboard_packet.wav
If URESAT-1 operates as intended, the project team plans to release a Linux
program that will allow players to send their chess moves to the satellite,
further enhancing the interactive experience.

SpaceX's Transporter-8 Mission Launches a Diverse Array of Smallsat Missions
SpaceX's Transporter-8 mission successfully lifted off from Vandenberg Space
Force Base in California during its afternoon launch window on Monday, June
12. Part of SpaceX's small satellite (smallsat) rideshare program,
Transporter-8 carries dozens of small to pico-sized satellites and orbital
test vehicles. This launch marks the 38th Falcon 9 rocket launch of 2023,
showcasing the rocket's significance as the major workhorse in the space
industry.
As a rideshare launch, Transporter-8 doesn't have a primary mission but aims
to lower costs for small spacecraft operators. The launch manifest for
Transporter-8 includes an eclectic variety of missions. Among them is
URESAT-1, a 1.5 P Pocketqube spacecraft from AMSAT-EA and the Spanish Amateur
Radio Union (URE), equipped with an amateur radio payload that will attempt
to play chess against opponents on Earth.
Transporter-8's diverse manifest demonstrates the wide range of missions
being pursued, from space manufacturing technology demonstration by Varda
Space Industries to two cryptocurrency technology satellites (CRYPTO3 and
MOXY-1) and a communications satellite for the Vatican (SpeiSat). This blend
of missions highlights the growing importance and potential of small
satellite deployments.
With its rideshare model, SpaceX is enabling more affordable access to space
for small spacecraft operators. By sharing the launch vehicle with multiple
payloads, the costs are distributed among different customers, allowing them
to realize their space ambitions at a fraction of the cost of a dedicated
launch.
The success of Transporter-8 adds to SpaceX's impressive track record, and if
the company maintains its launch pace while incorporating successful Falcon
Heavy rocket launches, it could be on track to achieve Elon Musk's ambitious
target of 100 rocket launches by the end of 2023. SpaceX's dedication to
advancing space exploration and commercial satellite deployments is evident
in its consistent launch operations and commitment to driving innovation in
the industry.

European Space Agency and S5Lab Announce LEDSAT Digipeater Challenge
The European Space Agency's (ESA) Fly Your Satellite! program in
collaboration with S5Lab is offering a unique opportunity for radio amateurs
around the world. The challenge is to establish communication through the
LEDSAT CubeSat digipeater, providing a chance to win a special prize: a QSL
card issued by the ESA Education Office and the LEDSAT team. Running from
June 26 to July 30, this challenge allows radio enthusiasts to engage with
space technology and showcase their communication skills.
LEDSAT, developed by students from Sapienza University in Rome's S5Lab
research team with support from AMSAT Italia, is an educational 1U CubeSat
that participated in the second edition of the Fly Your Satellite! program.
Its primary objective is to demonstrate a LED-based payload for ground-based
optical tracking. The successful launch of LEDSAT on Vega flight VV19 on
August 17, 2021, marked a significant milestone for the project. To celebrate
the launch, a competition was launched, encouraging participants from around
the world to record the first signs of life from the spacecraft.
To participate in the challenge, radio amateurs are invited to send a message
to the ESA Education Office ESTEC Ground Station, with the callsign PI9ESA.
The digipeater will be activated during specific time windows, with operators
stationed at the ground station to receive incoming messages. Upon successful
reception of a message, the sender's callsign and contact details will be
documented on a personalized QSL card, acknowledging their accomplishment.
The LEDSAT digipeater can store and retransmit digital messages sent to the
satellite, acting as a transponder for long-distance communication. Messages
can be retransmitted immediately or with an optional delay of up to two days.
LEDSAT follows a Sun-Synchronous orbit, resulting in two communication
windows each day β around midday and midnight β where contact can be
established. Participants can predict passes precisely above the ESTEC ground
station or their area of residence by using their favorite pass prediction
software or obtaining the latest Two-Line Elements for LEDSAT from
https://celestrak.org/NORAD/elements/gp.php?CATNR=49069.
Due to LEDSAT's monitoring and housekeeping requirements and the potential
high demand from operators, the digipeater activation time slots will follow
a pattern of one day ON and one day OFF, with the switch-on/off always
occurring at 00:00 UTC. This schedule will begin on Monday, June 26th at
00:00 UTC, and conclude on Sunday, July 30th at 24:00 UTC.
While the challenge is supported by operators on a voluntary basis, efforts
will be made to cover as many LEDSAT passes as possible, especially those
occurring around local midday on weekdays. A detailed schedule of pass
coverage will be published, so participants are advised to regularly check
for updates.
The LEDSAT digipeater uplink frequency is 435.310 MHz, the downlink frequency
is 435.190 MHz, and the modulation type is GMSK using a CSP + Golay + ASM
(AX100 Mode 5) protocol at 1200 baud. The LEDSAT team has prepared a software
package and a user manual for connecting to the digipeater, available for
download on the LEDSAT website at
https://www.s5lab.space/index.php/ledsat-digipeater/.
It is important to note that transmitting to the satellite is prohibited for
those who are not licensed radio amateurs. However, non-licensed individuals
can still participate in the challenge by listening to the messages
transmitted by the ESTEC ground station. If they provide evidence of
successful reception, including the date and time, they may also receive a
customized QSL card.
Participants are encouraged to mark their calendars, prepare their messages,
and not miss the chance to connect and communicate with the LEDSAT spacecraft
to receive their QSL card. Let's come together and make this event a
memorable celebration of our shared passion for space exploration and amateur
radio communication.
For any inquiries regarding LEDSAT or the digipeater challenge, please email
cubesats@esa.int.

Changes to AMSAT-NA TLE Distribution for 16 June 2023
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. Elements in the TLE
bulletin files are updated daily. TLE bulletin files are updated to add or
remove satellites as necessary 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 satellite has decayed from orbit and has been removed from this
week's AMSAT-NA TLE distribution:
MiTEE 1 NORAD Cat ID 47314 (decayed form orbit on 12 June 2023 per
Space-Track).

+ The Small Satellite Conference provides an extensive series of talks, speed
sessions, and posters that focus on successfully carrying out a small
satellite mission. From early wildfire detection using CubeSat images to UHF
ground stations for controlling satellites, topics vary wildly. The
conference takes place August 5-10, 2023 at Utah State University, Logan,
Utah. (ANS thanks Amateur Radio Daily for the above information)

+ United Launch Alliance (ULA) briefly test-fired the first-stage engines on
its new Vulcan Centaur rocket on Wednesday evening (June 7), completing a
crucial milestone for the boosterβΦs first flight. Vulcan Centaur is
designed to replace ULAβΦs current fleet of Atlas V and Delta IV Heavy
launch vehicles. The first stage can be supplemented with strap-on solid
rocket boosters for heavier payloads. ULA is gearing up for the first Vulcan
Centaur launch, which is likely to occur in July. The rocketβΦs primary
payload will be Astrobotic TechnologyβΦs Peregrine lunar lander, which will
carry payloads for NASA and private companies under the space agencyβΦs
Commercial Lunar Payload Services program. Vulcan Centaur will also carry the
KuiperSat-1 and KuiperSat-2 demonstration satellites for Amazon. The
spacecraft will demonstrate technology for the companyβΦs 3,236-satellite
broadband constellation. (ANS thanks the Parabolic Arc for the above

+ Capturing footage of the International Space Station (ISS) hurtling through
space at approximately 17,500 mph (28,000 km/h) is no mean feat, yet French
astrophotographer Thierry Legault has pulled it off yet again. In his latest
stunning footage, captured on June 9, Legault imaged the ISS whizzing past
three sunspot groups. The entire solar transit lasted just 0.75 seconds. In
addition, Legault captured these shots while two NASA astronauts, Stephen
Bowen, KI5BKB, and Warren "Woody" Hoburg, KB3HTZ, were carrying out a
spacewalk to install a new solar array outside the station. (ANS thanks
