Out of curiosity, what method is used to keep the International Space
Station from burning up?

I know that periodic boosts are done to raise the orbit.  Is that done
with rocket engines built into the space station?  If so, it seems that
storage and eventual reloading of the fuel would be difficult and high-risk.

Or is the ISS boosted using the engines of a docked vehicle?  That seems
like it would have its own set of complications.

Hi,
?
60 day predictions?on the Space-Track web site has ARISSat-1 object 37772?
re entering? 30th December.
Based on the?posts on this topic from??Nico,?Roland and James, and my
calculations, I think we have a bit longer.
But only a few days.

Periodic reboosts are thus necessary every few months, usually undertaken by
a Progress cargo ship docked to the Russian segment, or an Orbiter when
docked to Destiny.

Hi

Arissat-1 still working fine .

Transponder signal very good on a pass of 45 degrees.

Some additional information can be found here:

So engines on the Service Module of the ISS can be used
but usually Progress, ATV and HTV engines are used for
reboosts.

AMSAT-UK will be explaining the potential of the FUNcube satellite as a
teaching tool at the Association of Science Education (ASE) Conference Jan
5-7, 2012.

The ASE exists to provide support and ideas for school science teachers in
the UK. AMSAT-UK will be having a small stand in the marquee (number AS28).

The event takes place at the University of Liverpool. Admission to the
exhibition is free, but to avoid any queuing, you may wish to preregister on
the ASE website.

Hi all,
It may not be significant as I note from Roland that it was OK,    however
over here in Wales ( UK ) the pass
today ( Thursday 29th Dec. at 1345 hrs) it did not sound as healthy on the
downlink as I normally receive the satellite.
Did hear my downlink much weaker and also heard 2E0SQL also calling  CQ   -
 Peter also heard you yesterday you were much stronger but  did not get
back to you as my antenna was doing a 180 degree turn.
Will monitor the next pass and try to get an update on the status.

By the way, I note thankfully that all went well for the commercial launch
of the Soyuz ( Fregat )and its payload on Wednesday 28th   December.

Dear Luciano,
I am pleased to note  your report on the ARISSat-1 Transponder.  Would it be
possible for you or others to experiment with an SSTV picture through the
Transponder?  I did manage to get a complete image via the transponder in
November .  I  note there are  two others who have sent successful images
and hopefully there might be others while this historical satellite is still
in orbit!  Thanks for the efforts of those who might try.

Hi,

I had two passes of ARISSat today over New Hampshire.  The first one, I
only caught the tail end and got a Kursk frame or 2, but no satellite
telemetry.  The second one I had nice and strong as soon as it appeared
above the horizon, but it must have been in low power mode.  The
transmission cut off cleanly (no fade).  Then shortly afterwards it came on
again and cut off again.  I should have timed them but did not.  I had 3
periods of reception during the pass.   Unfortunately, none was long enough
to let the telemetry decoder get a frame.

Farrell, were you sending SSTV to the transponder around 1630Z?  It did
look like SSTV on the spectrum diagram but it was not doppler synchronized,
so it was drifting even when I synchronized.  It also disappeared long
before my pass was over, as I would have expected if the source were way
west of me.

Burns, W2BFJ
