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 it will not be possible in the near future, experts warn.
“According to the 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 sent the ship command to perform the maneuver, but because of the lack of telemetry do not know whether they were taken. Again, contact the experts will attempt to ship at night.
uncontrolled rotation of the ship got to the video
According to Tass another source in the rocket and space industry, the reason that “progress” can not communicate and take telemetry, can be uncontrolled rotation of the ship. Apparently, the space truck uncontrolled spins on its axis and its antenna is not directed towards the Earth.
“These videos from the ship indicate that it is very
rotates around its axis “- confirmed source ” Interfax “. Experts Mission Control Center issues a command to its stabilization, but whether it was possible to do it is not yet clear, he explained to the agency.
Note that the video from the “Progress”, which shows that the device actually turns, 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 to indefinitely. “The docking of a two-night scheme is practically impossible. So
way, on Thursday the ship will not be able to dock to the ISS, “- told” Interfax “experts Mission Control Center.
According to NASA , the ship could dock with the space station at five in the morning on Thursday (at noon 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 stage of the rocket “Soyuz-2.1a.”
Note that the command of the aerospace defense of North America (NORAD) calls the other figures. According to the Americans, the ship is in orbit with parameters of 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 tons of payloads for different purposes: fuel, oxygen, food, equipment for scientific experiments, parcels for 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 a momentous event.
