Default Its raining toilet rolls!

Or to put it another way, I hear the Progress did not make orbit.

Dark Star - great movie. Love the beachball 'alien' and the guy at the
end surfing into the atmosphere.

Hmm, OK I was of course joking when i said toilet rolls as you cannot use
such things in microgravity, put that down to my whacky UK humour. However
hopefully the issue will be located fairly fast. Seems a long time into the
flight to only still fall in Russia, but unfortunately no matter how careful
one is, failures do still occur in hardware. I guess one needs to find out
what that was, check the other items that are the same of similar, look at
if anything has been altered in the recent history, and gain some insight
into the cause that way. The smoking gun approach is going to be a bit
awkward if all you have is a pile of broken bits.
Hopefully telementry will point an accusing fingerr at a valve or sensor or
maybe even a controller issue. After all much of these things have
redundanncy, except of course and engine itself which is rather an unlikely
problem area these days assuming no changes of course.

The manifest of the Progress 44 was:

They have an article about the crash:

http://www.nasa.gov/mission_pages/st...44_launch.html

##
The ISS Progress 44 launched from the Baikonur Cosmodrome at 9 a.m. EDT
(7 p.m. Kazakhstan time) August 24 on a Soyuz U rocket, bound for the
International Space Station. At 5 minutes and 25 seconds into flight,
the Soyuz rocket experienced a third-stage engine shutdown due to an
anomaly. Given the trajectory and energy, the Progress did not reach
orbit and landed in the Altai Region of Russia.

There has never been a Progress loss during the International Space
Station Program. As of August 2011, the Russian Space Agency had
launched 745 Soyuz-U launch vehicles. There have been 21 launch failures
and 724 successes

If I understand correctly, 1st stage are the engines around the main
tube. They go away like SRBs on shuttle, and the 2ns stage is an engine
under the main tube. 3rd stage would be an engine on the main tube after
the bottom portion of the tube separates. Is that accurate ?



NASA says it landed in the Altai Region of Russia. My buddy Mr Google
says it is not far from the the Kazakhstan border (north east border
between Kazakhstan and Russia). Definitely not "Eastern Russia" as BBC
stated. Maybe Mr Google is wrong.
