Quote from: PahTo on 04/28/2015 02:31 pmDoes this version of Soyuz employ the RD-0110 or the RD-0124 for 3rd stage propulsion? Implications for the manned version are obvious if gear is common.RD- 0124 I believe. Of course, even if the problem wasn't with the third stage, the Soyuz still employs the same KURS system as Progress as well as other similarities across the board. I would therefore guess that there will be repercussions with the Soyuz as well.

NASA commentator said a short time ago the Progress was 4000km ahead of the ISS. Next Russian ground station pass is at 8:50 PM Houston time tonight. Any bets on whether the Progress will still have power at that time?

If there's a problem with the next Dragon, then Dragon is stood down. That's the problem....not the vehicle failing to arrive, but the vehicle being stuck on the ground for a lengthy period of time before being able to launch again.
This seems new on M-27M, anybody ?Speculation: did it make contact during sep. ? (therefor inducing a spin ?)EDIT:should have been more clear, it was a two part question, first anybody know what that new antenna (?) it is not on 26M, and second, contact anywhere in general during sep, or upper stage issue (BBQ roll etc.)

If employees are worried about their bills at home etc. they can't focus on their jobs and mistakes happen. It's a fair question no?

Spin rate was induced around sep after engine cutoff. Separation system would have started it and Progress deployments accelerated it is a good theory based on the data to date.
Didn't they have Luch satellites to be able to communicate with the spacecrafts from above?

Even with Progress flying, that would make things tight.Essentially, what I'm saying is that ISS is now zero fault tolerant to another resupply craft failure - with ATV gone, Cygnus' failure last year, today's Progress failure, and only one HTV this year, a Dragon failure would essentially cut ISS' regular supply line to Earth. If they couldn't get it back quickly, that would be the issue.
If they are unable to get sufficient data for root cause analysys, how long would this vehicle be grounded?
