space truck “Progress M-27M” launched into an unplanned orbit, after a long decline destroyed by logging into the atmosphere. The remaining fragments fell into the Pacific Ocean. In connection with the accident flight program has been changed. In particular, the three astronauts will have a month stay on the ISS. Roskosmos promised to tell the reason for abnormality on the results of the commission’s work, but unofficially it is already named.
On Friday, the Federal Space Agency said that the space truck “Progress”, unsuccessfully put into orbit, permanently lost.
«This is a technical problem with a particular product, it is a special case, not a system» «TGC” Progress M-27M “ceased to exist in 05.04 MSK May 8, 2015. Log into the atmosphere occurred at 160th turn of the central part of the Pacific “, – reported on the website of Roskosmos.
« The results of the investigation of an incident involving a freelance breeding TGK “Progress M-27M “will be presented no later than 13 May following the completion of the work of the state commission,” – said in a statement.
US Strategic Command has confirmed that the ship was destroyed by entering the dense layers atmosphere. At the same time the US military said they had not engaged in predictions about what will happen with the spacecraft re-entry into the dense layers of the atmosphere and where the debris may fall.
Summed up the third stage
The ship fell into the 900 km west of the Marquesas Islands in the central Pacific Ocean, a source told Tass in the space industry.
He added that the cause of abnormality was the late inclusion of the third stage of the rocket. “The reason for the emergency start-up” progress “- the failure of the third stage of the carrier rocket” Soyuz “. According to preliminary data, there was a delay in the inclusion of third-stage engine, “- he said.
According to him,” it is a technical problem with a particular product, it is a special case, not a system. ”
Earlier, another industry source said that the state commission studying the causes of the accident, came to the conclusion that it blame the problem in the “Soyuz-2.1a».
The Russian Space Agency did not comment on this information, promising to report on the findings of the state commission, after May 13, when the state commission shut down.
«If this is the third stage it is a question about a technological marriage. I do not think we can talk about a vice construction “, – he told the newspaper VIEW, Corresponding Member of the Russian Academy of Cosmonautics. Tsiolkovsky, Yuri Karash.
According to him, all the same questions remain. “For example,” Progress “Nonstandard department. And where was the stabilization system? Why it did not work? After all, she had to stop the rotation and give the ship the required position in the orbit, after which he was to seamlessly go to the station and dock with it. Why did this not happen? The third stage has nothing to do with it “- said the expert.
The program changed
Because of the accident flight program has been adjusted. In particular, the astronauts will return to the ISS on the ground not on May 14 as planned, and on June 11.
«It was decided that the Russian Anton Shkaplerov, Italian and American Samantha Kristoforetti Terry Verts linger the International Space Station for about a month. Planting of “Soyuz TMA-15M” with them is scheduled for June 11 in Kazakhstan “, – said on Friday a source of” Interfax ».
The source told Tass that the launch of manned spacecraft “Union” with the next expedition to the ISS is scheduled to move in July. “At the end of June – early July to send to the ISS cargo spacecraft” Progress “, and after that – in the 20 days of July – the story manned launch” Union “, – he said.
According to him, such a proposal was put forward by the working group for consideration by the Board of the Russian Space Agency chief designers of the manned program. The proposal has not been approved, said the source.
However, according to the source, due to the fact that, according to preliminary findings of the state commission, the accident led to the emergency situation in the third stage launcher “Soyuz-2.1a” requires more time for review and are already manufactured at the factory of rockets, as well as needs test launch an unmanned spacecraft to avoid risking human lives.
Earlier, in connection with the accident truck Space Mission Control Center (MCC) has given the crew of the International Space Station to save recommendation replaceable elements of life support systems.
«Progress” is not drove to ISS 2.5 tons of various cargoes, including nearly a ton of supplies for life support systems. In the case of savings on the ISS it comes to the power supply system, the water recovery system of condensate, air conditioning system, the production of oxygen and removal of carbon dioxide, the thermal control system, hygienic sewage disposals.
At the same time, the supply of oxygen, food, water and other vital elements of the station should be enough for a few months.
