Hi Roland. That is really impressive. May I reproduce your graphs for a display for our schools physics classes ?? Callsign left in place so they can 'google' your call.

[amsat-bb] Alive and kicking on 12/28 1812z NA pass - Re: Re: ARISSat-1 Dead? - No, Sir!
Just copied Arissat-1 including the English and Japanese messages, some details on battery voltage, along with the SSTV transmission. Have some cleanup to do on the wav file to get rid of the static before/after the transmissions (currently 16 MB !!), but will post it (where should it go?) Kind of scratchy but I was using an Arrow antenna indoors. Best copy is probably the SSTV transmission. 73 Bruce - W3NJ -Original Message- From: Craig Gagner crgag...@charter.net To: 'Clint Bradford' clintbra...@earthlink.net; 'AMSAT' AMSAT-BB@amsat.org Sent: Tue, Dec 27, 2011 6:53 pm Subject: [amsat-bb] Re: ARISSat-1 Dead? - No, Sir!

[amsat-bb] ARISSat-1
I wanted to let W6IHG that I did hear him through ARISSat-1 during my 1817 UTC pass. I have an audio recording of that pass. I believe I also heard WB2OQQ. There was also a station sending SSTV through the transponder but the station was not using Doppler. He went right out of the bandpass. I tried to follow but could not. I noticed that even though ARISSat-1 was in full sunlight, it went into Low Power mode. I was able to get a pretty decent SSTV copy during that pass, also. I am trying to determine what I am going to do when it terminates. It has taken up a good portion of my operating since August 4th. HI HI. There is another pass coming up in 5 mins (1951UTC). It will be a 13 degree pass so that should be pretty decent also. 73, -- *Carl W8KRF* ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: ARISSat : only a few more days !
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. Wayne Estes W9AE Oakland, Oregon, USA, CN83ik ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] ARRISSat-1 Decay from Space-Track
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. 73 John G7HIA ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: ARISSat : only a few more 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. http://suzymchale.com/ruspace/issorbit.html -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of Wayne Estes Sent: Wednesday, December 28, 2011 4:16 PM To: amsat-bb@amsat.org Subject: [amsat-bb] Re: ARISSat : only a few more days !
