The incident on the Space Station
The incident on the Space Station
A small incident has moved the hornet's nest.
On August 30, NASA reported the status of the International Space Station (ISS, in English) with a statement in which they reported the detection of pressure loss in the complex. The crew of Expedition 56 was asleep and they did not wake them up at that moment because it did not seem like a dangerous loss. When they woke up, the procedures of the mission controllers in Houston and in Moscow began to determine the location of the loss.
The six crew members, Commander Drew Feustel, flight engineers Ricky Arnold and Serena Auñón, Alexander Gerst of ESA and Oleg Artemyev and Sergey Prokopyev of Roscosmos, meeting in the Russian segment of the ISS, after several checks, reported that the loss appeared to be on the Russian side of the orbital complex.In a following statement, NASA reported that the pressure was regularized after repair in one of the Soyuz ships coupled. It was a hole two millimeters in diameter in the orbital compartment or upper section of the Soyuz MS-09 coupled to the Rassvet module of the Russian segment.
The Soyuz MS-09 was launched in June towards the ISS with the crew of the Expedition 56/57 Serena Auñón, the Russian Sergey Prokopyev and Alexander Gerst of ESA. He will return to Earth in December with the same three people. "The ship will be saved with the use of the repair kit", Rogozin, director of Roscosmos told Sputnik News, according to Space.com.Now, two weeks after that minor incident, NASA issued a joint statement with Roscosmos:
"NASA administrator Jim Bridenstine and the CEO of Roscosmos, Dmitry Rogozin, met for the first time yesterday, via teleconference, to discuss the status of the ISS operations in response to a request from Roscosmos." "As part of the discussion, Rogozin informed his US counterpart of the decision to establish a commission led by Roscosmos to investigate the cause of the loss in Soyuz (MS-09 / 55S) currently coupled to the station."
"The Administrator and the Director General noted speculation circulating in the media about the cause of the possible incident and agreed to postpone any preliminary conclusions and provide explanations until the end of the investigation."
"They affirmed the need for greater interaction between the technical teams of NASA and Roscosmos to identify and eliminate the cause of the loss, as well as the continuation of the normal operations of the ISS, recognizing that the entire crew is dedicated to the safe operation of the station and ships coupled to ensure the success of the mission. "
"The Administrator and the General Director agreed to meet in person for the first time at the Baikonur cosmodrome around 10 October when the NASA Administrator will visit Russia in conjunction with the launch of the next Soyuz crew of astronaut Nick Hague and cosmonaut Alexy Ovchinin. . "I believe that the communiqué tries to go to the crossroads of unofficial versions commented on websites about the possibility that the hole was made on purpose.
The incident was minor, but it is worth reflecting on how something simple can be catastrophic in space. A 2-millimeter hole seems nothing. As long as it is a coupled ship, the only consequence is a loss of pressure. However, then the ship will be uncoupled to return part of the crew of the ISS to Earth, and in that case, a small hole could be a major disaster.
In the initial image you can see an outline of the IEE configuration for the date, with three ships attached, the Soyuz used to transport crew and the Progress 70 that is used for cargo. In addition, the BEAM module (Bigelow expandable activity module) is indicated.
