The rotation of the cargo ship “Progress M-27M” around its axis due, most likely, a freelance separation from the third stage of the rocket “Soyuz”. At the same time, as reported in the Russian Mission Control Center, with each new revolution chances of survival “Progress” are reduced.
“If the ship can not be saved, it will unmanaged and uncontrolled decayed – explained,” Interfax ” MCC. – In this case, the fall zone of unburned debris in the atmosphere can be anywhere in the range between 52 degrees south and 52 degrees north latitude “.
An analysis of the orbital parameters shows that the two-stage rocket” Soyuz ” worked normally. Failure occurred at the stage of the third stage, experts say. Because of this ship was in orbit above the calculated value. In addition, there is a strong rotation around its axis it.
In the MCC noted that it was an unintended separation of the third stage and the ship could cause accelerated rotation.
The upcoming night around 4:00 and at 6:00 am Moscow time, attempts will be made in the TORU give the ship the team to neutralize the rotation. “While the ship is stabilized around its axis, there can be no maneuvers with him, including rendezvous and docking with the ISS,” – said the expert.
Experts Mission Control Center for several hours trying to get back into the proper orbit truck “Progress”. During the day the ship has more than five turns around the Earth. When he was in the zone of the Russian ground radio, attempts were made to establish reliable communication with him. However, they were unsuccessful.
The ship was launched from Baikonur in the morning on April 28 at 16:07 and still had to deliver to the ISS oxygen, fuel, food, water and a copy of the Banner of Victory. But almost immediately after starting refused feedback – in MCC ceased to receive telemetry data.
