Emergency space truck “Progress” started uncontrolled drop – NEWSru.com

The spacecraft “Progress M-27M”, which was to deliver the cargo to the International Space Station (ISS), but because of the emergency situation not out the calculated orbit, began an uncontrolled fall.

 “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 the source RIA “Novosti” in space industry.

 According to the source, date and accurately calculate the impact area of ​​unburned in the atmosphere fragments of “progress” is possible only for a few hours before it happens.

In this case, even if the “Progress” will fail, a copy of the Victory Banner, which, as previously assumed, was on the ship, will not be affected: Roskosmos announced , an artifact that was brought to the ISS earlier flight. “Victory Banner is on the International Space Station. It was delivered on March 27, manned spacecraft” Soyuz TMA-16M “with a crew of commander, Roskosmos cosmonaut Gennady Padalka, flight engineers – Mikhail Kornienko (Roscosmos) and Scott Kelly (NASA),” – said Federal Space Agency.

The application Roscosmos many surprise. Some experts dared to doubt his veracity as Roskosmos earlier reported that the flag was handed over to its representatives in April. “Therefore, no delivery banner in March could not be. What a lie?” – Commented on the new statement of the Federal Agency chief editor of “Echo of Moscow” Alexei Venediktov.

  The insurance does not reimburse the machine

Meanwhile, experts have estimated the damage from the loss of “progress”. According to them, it will be five billion rubles, “Interfax”. At the same time, according to the agency, the ship was insured in the “SOGAZ” and “Ingosstrakh” two billion rubles.

 Previously it assumption , that fragments of the ship will fall to Earth May 7-11. This was reported in the Mission Control Center (MCC).

 Prior to this it was assumed that because of the fact that the ship is not stabilized and rotates on its axis, its decayed and fall can occur even earlier – on May 3-4. After that, he will go into the atmosphere and burn up, the source said Tass in the space industry, engaged in providing ballistic Russian spacecraft.

 Earlier, there were reports that the ship may have already started to crumble. This may indicate a few dozen fragments of which are found in orbit by the US military, according to SatNews .

In total, according to the site, there were 44 fragments. To establish their exact belonging to the “progress” American specialists have not yet succeeded. USAF Space Center who discovered the wreckage, continues to monitor the situation. Meanwhile, a member of the Russian Academy of Cosmonautics, Yuri Karash suggested in an interview with “Interfax” , if the ship started to fly off the wreckage, most of all, he suffered a serious attack and is already falling.

  How to “Progress” missed the orbit

 “Progress M-27M” was launched into orbit yesterday. Immediately after the removal of the ship from the carrier rocket “Soyuz-2.1a” began to receive reports of non-disclosure of antennas rendezvous system “Kurs”. Then it turned out that the ship is an unplanned orbit. Later it became clear that he was uncontrollably orbits, which is 30 kilometers above the orbit of the ISS.

Since yesterday, the experts tried to regain control of the flight of “progress”. By ship sent signals, but no response at MCC did not. Experts have tried to run the truck engines to perform “corrective maneuver”, but these actions were unsuccessful.

 Between 3:50 and 4:10 Moscow time held a regular session with the ship, but he did not give any results. After it became known that the new attempts to contact the ship will not be taken. In addition, attempts to take control of the ship also stopped in the reported media sources in the space industry.

 “Progress” was to deliver to ISS more than 2.5 tons of payloads for different purposes: fuel, oxygen, food, equipment for scientific experiments, parcels for cosmonauts and astronauts.

The damage from the loss of “progress” is estimated at five billion rubles. Due to the emergency situation with the ship can be moved to the launch of manned spacecraft “Soyuz TMA-17M” with the crew of a new expedition to the ISS, scheduled for May 26. This is due to the fact that some elements of the “Progress” is the same as that of a manned “Soyuz”. In particular, the system of rendezvous and docking with the ISS, “course” of these ships is the same, said Wednesday Tass source at the Baikonur Cosmodrome, where the ship will have to start.

 Scheduled next cargo flight to the ISS should make an American ship Dragon, created by a private company SpaceX. In NASA made it clear that it will be his seventh rendezvous with the orbiting complex, and it must take place “no earlier than 19 June.” It will bring about 2.5 tons of payload and materials for scientific experiments, reported in the US space agency.

state of emergency with the ship “Progress”

media noted that this is the first of this type of emergency situation for the time of operation of ships “Progress”. According to RBC , it can be considered one of the most reliable spacecraft.

The previous incident with the “progress” has occurred April 24, 2013. The Russian space truck “Progress M-19M” not revealed the antenna system of automatic rendezvous and docking, “course”, after he was separated from the third stage of the carrier rocket “Soyuz-U” was put into orbit. Repeated attempts to uncover the antenna during the passage of “Progress M-19M” over the zone of action of ground tracking stations specialists also failed transfers RIA “Novosti” .

Another state of emergency with “progress” happened Aug. 24, 2011. After the start of a new cargo ship “Progress M-12M” in the area of ​​the third stage of the rocket “Soyuz U” 325 seconds of disruption occurred propulsion system, which led to its emergency shutdown. Space Debris truck, not burnt up in the atmosphere, fell in the Altai Mountains. Death and destruction on the ground was not, the agency said.
