According to the See Sat L satellite mailing list, the spacecraft have been found in the same orbit as before the burn, after the planned burn time. http://www.satobs.org/seesat/Nov-2011/0069.html

After the planned first burn of the engine, the spacecraft was not found in the predicted orbit. Alternative radarobservations preliminarily show that there are two objects in the orbit with parameters the same as before the plannedengine burn. Observers are requested to attempt to discover the spacecraft in the initial LEO parking orbit.

How do you swear in Russian?I was really hoping this would be successful. Might still be a chance to salvage this somehow since the upper stage is solar-powered, right? If the spacecraft can receive commands and transmit responses, there's still a chance...
it's still on orbit and have power, waiting some watchdog-timer to reset...
Bruno, this adds IMMENSELY to this discussion, multo obrigado, and thank you. We are watching this launching with special anxieties and you have helped give us better feelings.If you hear of any other news media coverage -- radio, TV -- about other sightings, please, PLEASE relay them to us here as quickly as you can.The timing and direction of your sighting is important, to make sure it really was the probe and not a coincidence with aircraft. Email me separately if you want some of my research reports about OTHER rockets that were seen in the skies over Brazil, in years past. Mostly, people thought they were OVNIs.Jim O -- very grateful to you![email protected]

SC performed TM downlink via all available channels, this is indicating an anomaly detected by SC computer. During SC testing, Roscosmos inserted an SC slew commanding sequence in the flight program to point the SC's antennas toward the North (to be pointing at U.S., European, Russian ground stations) in the event of a problem before the burn(s) so that data can be more quickly obtained. This allows them to analyze the data and try again another day since MDU is completely powered by SC's solar panels. Goldstone DSN is indicating that SC is in a contingency safe mode. Contact was lost at planned LOS (with no first burn) and was picked up by Europe's first tracking station, TM unreadable at moment. Sun pointing for solar panels may not have been established before battery charging was commenced by flight computer. SC can be commanded to reset if need be.
http://www.satobs.org/seesat/Nov-2011/0071.htmlPhobos-Soil:Some indications are that it may be in "safe mode". Let's hope.Would be passing observers in Ecuador at the moment - only visible if therewas an engine plume.
Thanks! It sounds like they may be able keep this mission alive if they can get the flight computer back? If that's even possible?
Correct I'm not in, but I can make a few phone calls. Want a L2 thread for internal updates Chris?

If that's even possible?Roscosmos and NASA are both probably hoping that programming is not the issue. NASA JPL supplied the auxiliary flight control computer, at the request of the prime contractor with approval from Roscosmos, to increase chances of mission success. Both are turned on for launch through TMI with JPL computer taking over after last orbit correction burn to perform Mars System insertion. JPL computer is then turned off until Phobos launch of Sample return SC back to Earth.

QuoteThanks! It sounds like they may be able keep this mission alive if they can get the flight computer back? If that's even possible? It's parking orbit will certainly keep it up there for a few more days, but not much more. And the Russians do have better computers and software than they had in 1996. But there is the problem of Solar orientation for the F-G solar panels.And even if it has reliable power and is perhaps in a safe mode,and if the Russians were able to reestablish communication with ithow would they know how much mass the orbiting-assembly has now (something separated & drifted off the craft)? They can't just fire up the rocket motors on that orbiting craft without knowing all the details and expect a successful TMI.
