NOAA-18 Decommissioned
*NOAA-18 (Credit: NOAA)*
On May 31, 2025 at 1605 UTC, the NOAA-18 S-band Transmitter 4 (STX4)
experienced a power drop from 7W to 0.8W. STX4 is the only remaining
transmitter used for up-link (commanding) and downlink (telemetry & global
science data from the recorder). Full recovery of the S-Band transmitter
and its functionality is not possible, and therefore jeopardizes the
ability to ensure safe operation of the spacecraft. Based on NOAAâ€Ös
requirement to responsibly manage on-orbit assets, NOAA decommissioned
NOAA-18 on June 6, 2025 between 1733 and 1749 UTC and the APT signal
transmission ceasing was observed by amateur observers.
NOAA-18 is a legacy Polar Operational Environmental Satellites (POES)
satellite and is operated with no performance or latency requirements.
Users should transition to NOAA's Joint Polar Satellite System (JPSS).
JPSS provides global observations that serve as the backbone of both short-
and long-term forecasts, including those that help us predict and prepare
for severe weather events. The five satellites scheduled in the fleet are
the currently-flying NOAA/NASA Suomi National Polar-orbiting Partnership
(Suomi NPP) satellite, NOAA-20, previously known as JPSS-1, NOAA-21,
previously known as JPSS-2, and the upcoming JPSS-3 and JPSS-4 satellites.

Request for Expression of Interest for futureGEO Project
As part of AMSAT-DL's cooperation with the European Space Agency (ESA) to
prepare a future geostationary amateur radio payload project (“futu
reGEOâ€),
a *Request for Expression of Interest (RFEI)* was recently sent to national
AMSAT organizations, amateur radio associations and qualified experts
worldwide.
The aim is to identify potential partners who would like to actively
participate in the definition and development of a new amateur radio
payload for a future geostationary satellite. Contributions should include
innovative technical ideas, experiences from previous missions (e.g.
QO-100) as well as concrete proposals for payloads, experiments and
educational initiatives.
In particular, amateur radio organizations whose countries are members of
the ESA or which are in the planned visibility range (footprint) are
addressed. This means Canada, Europe, North and South America, and Africa.
Call for expressions of interest (RFEI) for futureGEO project
Unfortunately, we have noticed that not all contact details in the â€
œAMSAT
International Directory†are up to date. *(Editor's note: Internati
onal
AMSAT organizations should submit updated contact information for key
leaders to info at amsat.org <http://amsat.org> to update this directory) *
If
you are an organization that has not received an RFEI but would like to
actively participate, please contact us directly.

*The deadline for expressions of interest is June 30, 2025.*
We look forward to your feedback and hope for committed international
cooperation on this forward-looking project!
*Editor's note: The AMSAT Board of Directors and senior leadership will be
submitting an expression of interest. A geostationary amateur radio
satellite with a North American footprint has been sought for a very long
time and AMSAT is committed to providing AMSAT-DL with any support that we
can provide in this endeavor.*

SO-125 FM Transponder Activated
*SO-125 (HADES-ICM)*
On the evening on June 5, 2025, the SO-125 FM transponder was activated for
the first time. AMSAT-EA intends to activate the FM transponder on Fridays,
Saturdays, and Sundays moving forward. Initial reports are that the
satellite's transponder works well. QSOs have been made via the satellite
in all regions of the world.
The satellite has a 145.875 MHz uplink and a 436.666 MHz downlink. The
NORAD ID for Keplerian elements is 63492.
AMSAT has submitted a request to the ARRL to have SO-125 added to the LoTW
configuration file for LoTW QSO confirmations.
SO-124 (HADES-R) continues in 24 hour operation with a 145.925 MHz uplink
and a 436.888 MHz downlink. Wednesdays are reserved for digital modes.

Changes to AMSAT TLE Distribution for June 6, 2025
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/
<https://www.amsat.org/keplerian-elements-resources/>.

ARISS News
Amateurs and others around the world may listen in on contacts between
amateurs operating in schools and allowing students to interact with
astronauts and cosmonauts aboard the International Space Station. The
downlink frequency on which to listen is 145.800 MHz worldwide.
*Scheduled Contacts**School in the Aznakaevsky district of the Republic of
Tatarstan, Tatarstan, Russia, direct via TBD*
The ISS callsign is presently scheduled to be RSØISS
The scheduled crewmember is Sergey Ryzhikov
The ARISS mentor is RV3DR
Contact is go for Sun 2025-06-08 09:05 UTC

Many times a school may make a last minute decision to do a Livestream or
run into a last minute glitch requiring a change of the URL but we at ARISS
may not get the URL in time for publication. You can always check
https://live.ariss.org/ to see if a school is Livestreaming.
As always, if there is an EVA, a docking, or an undocking; the ARISS radios
are turned off as part of the safety protocol.
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.
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

Satellite Shorts from All Over
+ The FCC has denied AST Space Mobile's request to use 430 MHz -440 MHz for
telemetry operations, noting "There is no space tracking or space
telemetering allocation in the 430-440 MHz frequency range." (Thanks to
AMSAT-DL and the FCC for the information)
+ A paper by Hope Lea, KD2L, and Ruth Willet, KM4LAO, entitled "Empowering
the Next Generation Through Space Communication" was selected best in "The
Next Generation" part of the SpaceOps 2025 conference in Montreal. This
paper discussed ARISS and YOTA. AMSAT congratulates them on their
outstanding work! (Thanks to ARISS for the information)
+ The FCC's #FridayFlashback on X this past week highlighted amateur radio.
