I have just received word from the project that there seems to be a serious problem.
After the planned first burn of the engine, the spacecraft was not found in the predicted orbit. Alternative radar
observations preliminarily show that there are two objects in the orbit with parameters the same as before the planned
engine burn. Observers are requested to attempt to discover the spacecraft in the initial LEO parking orbit.
This is the official pre-launch estimated TLE of the LEO parking orbit:
1 55500U 11000A 11312.95486111 -.00010748 00000-0 -11606-4 0 14
2 55500 51.4279 0.6058 0106375 25.7555 298.8256 15.98414689 33
I imagine that one of the two objects seen on the radar could be the final stage of the booster. Accurate descriptions
and counts of the number of objects seen, as well as position and time would be useful.

My friend at U.S. Deep Space Network's control center provides the following:
U.S. DSN's Goldstone Antenna Complex received one ping from Spacecraft. 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 cannot be confirmed at this time (may not have been established before battery charging was commenced by flight computer). SC can be commanded to reset if need be. Phobos-Soil:
Some indications are that it may be in "safe mode". Let's hope.
