Packet Module status on board ISS
received several reports stating that the packet system
on ISS is down. Here is what we know and our current
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
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
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.
