I wonder if this a bit of shades of Gemini VIII here? Stuck thruster? That could explain the high rotational rate and why it was only in one axis.
Quote from: satwatcher on 04/28/2015 12:02 pmGround track map as shown on NASA TV shows it late with respect to the 123 to 127km perigee orbits published by space-track, suggesting it did boost its orbit.... suggesting that these orbits were erroneous.

This seems new on M-27M, anybody ?Speculation: did it make contact during sep. ? (therefor inducing a spin ?)

UPDATE (8:15 a.m. EDT): Russian flight controllers are continuing to troubleshoot issues with the ISS Progress 59 cargo craft. The spacecraft made another pass over Russian ground stations and continued to experience telemetry problems regarding the deployment of navigational antennas and the pressurization of the manifolds in the propulsion system. Flight controllers also confirmed that the vehicle had entered into a slow spin and have issued commands to attempt to control it.....As Progress passed over Russian ground stations, the Russian flight control team issued commands through the telemetry system onboard the spacecraft in an attempt to receive confirmation that navigation and rendezvous systems had deployed. But, due to sporadic telemetry from Progress 59, inconclusive data, and trouble uplinking commands to the spacecraft, controllers were unable to confirm the status of the systems.
Interesting from the NASA TV update. Houston stopped planning for a Thursday docking and informed Moscow of the same...
Quote from: Targeteer on 04/28/2015 12:34 pmInteresting from the NASA TV update. Houston stopped planning for a Thursday docking and informed Moscow of the same...Might this be because the Progress has now spent too much time on the lower orbit and has gotten too close in regard to ISS to get to a docking on Thursday? Remember that lower orbit will "catch" a higher orbiting object. I remember a rule of thumb of x altitude difference will get a 10x distance in the track.
