Not looking good for the latest unmanned supply vehicle for the ISS.

Tumbling at 72deg/sec means getting a coms lock is going to be very difficult isn't it? Do we know if the craft has internal stabilisation from an IMU etc?

I believe it does, but some of the video shots are apparently showing a self-diagnosis with an internal gyro having failed, presumably that's why it hasn't self-corrected by now.

What I have gathered from the Guardian live stream, 17,000 mph, just flew over London. Week, week and half before it eventually crashes down.

17,000 mph is the normal speed for low earth orbit objects.

When it re=-enters it will burn up. The progress craft has no heatshield and is not designed to survive re-entry. ALL progress craft re-enter after they undock from the ISS and they all burn up.

Unfortunately, it won't survive long enough for it to be seen visually from the UK. A visual pass would show that it is tumbling.

Hope the remains miss anyone, especially any fuel that may survive.

It's down - re-entered last night just west of Chile with debris possibly falling as far as the Falklands

Is this the one that the Sun was reporting might crash-land somewhere off the coast of Southend, at the mouth of the Thames Estuary? Got that a bit wrong didn't they?!?eek

The craft could have come down anywhere under its orbital track. When the means to deliberately initiate re-entry has been lost - as was the situation in this case - then the craft will re-enter of its own accord and no one can be 100% sure at what point the re-entry will commence except that it will be under the orbital track.

Knock-on effect of the failure - crew rotation delayed

"Food supplies in the ISS are said to be at dangerously low levels. In a totally unconnected incident, one of the cosmonauts appears to have gone missing. When asked about the matter, fellow cosmonaut Alexander Alexandrovich Alexanderski said 'We just don't know where he's gone. Burp.'".

Possibly related - Sarah Brightman has 'postponed' her ISS trip, citing 'personal matters' though cynics suspect a lack of cash
