Tyvärr har vi inte hört någon trafik från ISS på ett tag. Det verkar som att det kommer att ta en tid innan den kommer tillbaka. Det är som vi vet en stor utmaning att få amatörradio ombord på ISS att fungera.

Packet Module Status On Board ISS
ARISS has received several reports stating that the packet system on
ISS is down. Here is what we know and our current forward plan.
The packet system in the Columbus module started to act up late last
week, sending only a beacon. The ARISS team requested a power recycle
by the crew, and with that power recycle, the packet system appears to
have stop functioning completely. Note that this unit has been on-
orbit for 17 years. It was launched on the STS-106 Space Shuttle
Atlantis mission in September 2000 and was built, tested and certified
for flight about 20 years ago.
The ARISS team has had some extensive discussions on the way forward.
We would first like to do some additional troubleshooting with the
existing packet module. It will take some time (weeks) to develop
troubleshooting procedures, get the procedures approved by NASA and
then conduct the tests with the crew. This includes an additional
power cycle. The turnaround time is much longer than usual because a
new crew will soon be arriving on ISS. The current crew is focused on
the new crew arrival and there will be about a one- to two-week
transition after the new crew arrives. On the positive side, one
aspect of our troubleshooting?a second power cycle?will occur
automatically because ARISS is shut down during crew docking and
turned on afterwards. However, there will be more to our
troubleshooting than just the power cycle.
We have some additional plans with alternative solutions, but those
are currently being discussed and prioritized within the ARISS team.
All solutions will require international ARISS team coordination,
additional procedures and crew interaction. People who have
carefully followed ISS operations know that crew time continues to
evolve with the more extensive research that is occurring on-board.
Suffice it to say, it will take longer than what it has taken in the
past to work through this issue.
The above information is to make sure that ARISS properly sets
expectations on how long it will take to resolve this. At this point,
expect a few months with no ARISS packet.
As you all can see, deploying the Interoperable Radio system that is
currently under development by ARISS has become even more critically
important. The ARISS team is laser focused on getting that system
developed and deployed. We are conducting a final design review with
NASA on this system next week. But we cannot get to the finish line
without your help. If you can, please consider a donation to the
ARISS radio fund by clicking on the ARISS donate button on the ARISS
web page (www.ariss.org) or the AMSAT web page (www.amsat.org). All
donations, large and small are appreciated.
On behalf of ARISS, we thank you for your sustained interest and
support of our program.
