Future Orion MPCV Pilot
After watching that video, I am not so convinced that is a "slow spin" like NASA says. :uhh:

@ISS101 said:Roscosmos: Saw signs of Progress prop system depressurization. Telemetry from craft became off-nominal 1.5sec before separation from Soyuz.
From Twitter:
It would be hilarious if it falls near Moscow right on the victory day (it was supposed to deliver the flag to the ISS).looking at how to do a controlled de-orbit.
The crew would have to suffer for a week in a cramped space, then do a bone-bruising ballistic re-entry in a random spot on the planet and fend off sharks for the couple of days it would take someone to get there.Who knows what would happen had this happened on a crew mission? :blink:
Or maybe not. Cosmonauts are great problem solvers, and there might have been just a flick-of-a-switch worth of damage.
...Or SpaceX might have to do an improvised rescue mission.

Yeah, that sounds better. A rescue mission could come up, an unmanned Soyuz even, then the crew could transfer through an adapter, or EVA, to the other vehicle.
Yeah, it would look like the movie "Marooned". Which is something to be avoided...
Well, they have more oxygen, and the station is occupied. It might be possible to try to move something from the station to them.Yeah, it would look like the movie "Marooned". Which is something to be avoided...
Indeed.the uncontrolled fast spin would be a problem for any rescue
Would climbing outside with a gas canister and venting counter-spinwards be enough?
Were it manned I would more concerned with things like crew health, especially at that high spin rate. Over a few days that's gotta be bad for you. Then there are things like sun-pointing for power and thermal considerations, all of which are attitude-dependent.
The second stage doesn't enter orbit. The second stage is the long central core stage which has more or less remained the same since its creation for the R7 ICBM. Same for the four boosters which serve as the first stage. The third stage was a new addition to create the Soyuz from the R7. The Soyuz has undergone modernizations and upgrades throughout the years but in design it's essentially the same launch vehicle that was used to launch Soyuz 1 on April 23 1967.Any chance that the stage did not completely separate somehow, and that a third stage burn put the whole stack spinning? It would be interesting to know if NORAD has identified the separated second stage. Perhaps that might explain the debris?
The State Commission that has been assigned to investigate this has been given until May 13th to present a preliminary report. There's a Soyuz 2-1A (same LV used in this launch) to be launched from Plesetsk on May 15 with Kobalt M recon spacecraft so they like to know what if anything the launch vehicle had to to do with the loss of the Progress.Uggh...what a mess. They will certainly need to examine whether this could affect manned Soyuz.
