MOSCOW, April 29 – RIA Novosti. Federal Space Agency decided to reduce the orbit and flood the space cargo ship “Progress-M27M” as a continuation of the flight is not possible, told reporters the head of the space agency, Igor Komarov .
The causes abnormal excretion of a truck in orbit will be to find out a special commission of Roscosmos. Previously it believed that the incident occurred due to a problem in the separation of the carrier rocket and spacecraft.
abnormal situation occurred on Tuesday morning: a truck “Progress-M27M” after the launch of a “Baikonur” for unclear reasons, was launched on unplanned orbit and can not dock with the ISS. Now “Progress M-27M” continues its flight mode uncontrolled “spin”.
Total to date there are three separate issues: the so-called “spin” of the ship at a high speed, non-disclosure of multiple antennas automatic docking system ” Course “and the inability to receive telemetry from the ship and give him commands.
to do everything they could
Experts tried to revive distress in orbit” Progress “more than a day, but a full-fledged relationship with him and failed to establish.
“The transport ship in the near future can be considered debris, threatening security. Docking with the ISS is not. The engines of the fact that uncontrolled rotation stop fails, run a risk. In the uncontrolled twisting the ship flies certainly not less than a week, and then enter the atmosphere and burn up. Where – is unclear, “- told RIA Novosti source in the space industry.
On the first day trying to run the truck engines are not undertaken, and on Wednesday during the next passage of “progress” of the Russian zone of radio visibility of such an attempt was not successful.
In the middle of the day, it was decided to stop trying to contact truck. By lunchtime, it was reported that “Progress” started a gradual uncontrolled descent from orbit.
“Since the start the engine and take corrective maneuver fails, the space truck gradually loses orbit. The rate of reduction will vary depending on the state of the atmosphere and the solar wind, but overall the ship only for those hours lost tens of meters high, “- said RIA Novosti source in the space industry.
However, the First Deputy General Designer of RSC” Energia “, the head of the Russian mission segment of the ISS, Vladimir Solovyov on Wednesday night announced that the DRM will be up to the last attempt to establish contact with the space truck.
Flood – can not save
In the late afternoon the Federal Space Agency decided to gather journalists and explain what is happening with “progress.” Previously, such situations these trucks did not happen, so the incident is given a lot of attention, in part because it is the first state of emergency in the aerospace industry after the Roskosmos led by Igor Komarov. The situation of the monitor and the Deputy Prime Minister Dmitry Rogozin, and the Kremlin.
“In the course of further testing units ship today revealed no leaks in the line of the propulsion system. In this regard, the continuation of the flight of the transport ship, its safe docking with ISS is not possible “, – told reporters Komarov.
He said that an emergency situation is likely to have originated in the separation of the spacecraft and the launch vehicle. The same opinion was expressed earlier in an interview with RIA Novosti and academician of the Russian Space Academy named after Tsiolkovsky Igor Marinin.
Many concerns have caused US identified NORAD system orbit “progress” items of space debris. Experts said the RIA Novosti news agency, it may contain, dumps the separation of the third stage of the rocket from the truck. Roscosmos agree with this version.
The further fate of the space truck resolved – it will be flooded and will burn in the atmosphere before reaching it.
“With regard to the calculation of incidence and unburned fragments on Which countries – we mean it in a few days. Now, roughly, the ship “Progress” will complete its mission on May 5-7, “- said the first deputy designer general of RSC” Energia “, the head of the flight of the Russian segment of the ISS, Vladimir Solovyov.
Who is to blame?
In order to analyze the incident with space truck “Progress-M27M” Roskosmos created a subgroup of the state commission. It will have to prepare all the necessary proposals, which must be considered in the preparation of the next start.
The results and conclusions of the Commission shall provide until May 26, this is the date scheduled for the next manned launch of the program, whose mission – to deliver to the International Space Station Expedition new members.
The findings, who is to blame for state of emergency with “Progress”, will be made after all the circumstances, Komarov said.
“to understand, I think, the reason will be installed and we will inform about it. Although there are partners who work for the corporation (RSC “Energia”). Without removing the guilt and not shifting it on anyone, should determine the true causes, and then to conclusions, “- said Komarov at press conference in the Russian Space Agency.
Space Plan work will not suffer
Postpone scheduled for the second half of May manned space flight is not planned, including because this mission is to perform another modification of missiles “Union”, namely the “Soyuz-FG”, rather than the new “Soyuz-2.1a,” Roskosmos said.
But the plan launches new cargo ships for the current year will be adjusted.
“We will launch two adjustments” progress “this year. One will be put to the third quarter of this year, the second – on the fourth, “- said Wednesday the deputy head of the Russian Federal Space Agency Alexander Ivanov.
After the analysis of the existing provisions on board the ISS, it became clear that the crew is fully provided with all necessary to continue work before the arrival of the next space truck.
The head of mission of the Russian segment of the ISS, Vladimir Solovyov also assured that the clash between the space station and the truck is not possible, the crew is not in danger.
The next launch rocket “Soyuz-2.1a” is scheduled for May 15 from the cosmodrome “Plesetsk” in the interests of the Russian Defense Ministry. It will carry out calculations troops Aerospace Defense. To decide whether to be or not to launch, at the disposal of the War Department two days before launch date will give all materials to investigate abnormal situation with the launch of “Progress” in the “Soyuz-2.1a”.
The incident with the “progress” should not cast shadows on the reliability of Russian rocket “Soyuz”, convinced the deputy head of the Russian Space Agency Ivanov . According to him, these statistics successful launches no one family of launch vehicles in the world.
“What happened is some emergency situation that we are now is we can not explain, in no way can not deliver cross on the operation of launch vehicles family “Union”, “- said Ivanov.
