MCC: ship “Progress” can be lost – NEWSru.com

The space truck “Progress-M27M” with a copy of the Victory Banner , which is now the carrier rocket “Soyuz-2.1a” could not to bring the calculated orbit, may be lost if to regain control over them fail in the near future, experts warn.

“According to Russian measurement tools, which bases its calculations Mission Control Center (MCC), the ship is in orbit with a perigee of 193 km and an apogee – 278 km at a nominal value of 193 to 238 km,” – said Tass source in the MCC. According to him, in this orbit “Progress” can spend a few days in free flight, after which, if not carried out maneuvers, “the ship may be lost.” The source said that the PMU staff direct ship the team to perform the maneuver, but because of the lack of telemetry do not know whether they were taken. Re-contact with the vehicle experts try at night.

  uncontrolled rotation of the ship was on the video

 According to TASS another source in the aerospace industry, the reason that with the “progress” can not communicate and take telemetry may be uncontrolled rotation of the ship. Apparently, the space truck uncontrolled spins around its axis and its antenna is not directed towards the Earth.

“These videos show the ship that he strongly
 rotates around its axis “- confirmed source ” Interfax “. Specialists Mission Control Center issues a command to its stabilization, but whether it was possible to do so, it is not clear, said a spokesman.

Note that the video with the “Progress”, which shows that the device actually rotates, has already appeared on the Internet.

If the “Progress” will lose, the ISS will be enough food and water

 Docking with the ISS truck moved from Thursday indefinitely. “Docking for a two-night scheme is practically impossible. So
 way, on Thursday the ship will not be able to approach to the ISS, “-” Interfax “experts Mission Control Center.

 According to NASA , the ship can dock with the space station at five in the morning on Thursday (10 pm Wednesday Moscow time).

 “Even if the” Progress “does not fly to the station, the crew enough food and water, as well as fuel, since only recently arrived at the station an American truck Dragon, which restock the space station” – reassured Tass source in the space industry.

 Earlier, experts reported on the causes of failure, because of which “progress” could not in time to dock with the ISS. Tass source in the space industry said that the ship did not come into the proper orbit due to incorrect operation of one of the stages of the rocket “Soyuz-2.1a.”

 Note that the North American Aerospace Defense Command (NORAD) calls the other figures. According to the Americans, the ship is in orbit with parameters 123 km perigee (the lowest point of the orbit) to 306 km. Without correction of the orbit is likely to drop ship to Earth, according to NORAD.

 “Progress-M27M” was supposed to deliver to the ISS more than 2.5 tonnes of payloads for different purposes: fuel, oxygen, food, equipment for scientific experiments, for sending cosmonauts and astronauts. And against the backdrop of a copy of the Victory Banner astronauts had to congratulate the Russians on the 70th anniversary of the landmark event.
