The head of the Russian Space Agency (Roscosmos), Yuri Borissov, said on December 19 that a preliminary inspection of the Soyuz MS-22 spacecraft at the International Space Station (ISS) had revealed a small hole in the spacecraft compartment. ‘equipment.
The daily Izvestia quoted Mr. Yuriy Borisov: “The preliminary examination shows there is a small hole of about 0.8mm, causing leakage“. He described the situation as “not very nice” but denied speculation that the temperature inside the spacecraft had risen to more than 50 degrees Celsius.
The Soyuz MS-22 spacecraft has a small leak in its instrument compartment.
The Soyuz MS-22 spacecraft has a small leak in the equipment compartment.
Earlier on December 15, a pressure drop in the external cooling loop of the Soyuz MS-22 manned spacecraft was recorded. A visual inspection of the spacecraft from the orbiting outpost confirmed a coolant leak, leading to the cancellation of the imminent spacewalk.
Roscosmos conducted a series of tests on the Soyuz MS-22 spacecraft’s systems, including its thrust control system, and found no other defects.
According to TASS, Roscosmos said the temperature inside the Soyuz MS-22 spacecraft has stabilized above 30 degrees Celsius.
“In the first days after the leak, system tests showed temperatures above 30 degrees Celsius in the habitation module of the Soyuz MS-22 spacecraft and above 40 degrees Celsius in the equipment compartment. However, In recent days, when the spacecraft’s systems were turned off, the temperature in the compartments stabilized above 30 degrees Celsius. – said the Roscomos announcement.
Still according to this agency, the increase in temperature inside the Soyuz MS-22 spacecraft is within acceptable limits and does not seriously affect the equipment and health of the astronauts in case they are present at the inside the spaceship.
The above leak caused the spacecraft’s coolant to spill into space, as the world witnessed through videos released by NASA. Many people are concerned about the safety of the astronauts working on this ship, including 2 Russian experts and 1 NASA expert.
This weekend, Mr. Tommaso Sgobba, President of the International Association for the Advancement of Space Security (IAASS) and former ESA Director of Space Flight Safety, had an interview with Space newspaper, in which he expresses his biggest concern: the Souz ship is not capable of returning to Earth – something to which Roscosmos has not officially responded.
If this ship fails, the three astronauts mentioned above could be stranded on the ISS for months before a rescue ship from Earth arrives, and unable to evacuate if an incident occurs with the ISS. space station.
On the station there is only one Space. This is a tailor-made outfit that only works when it fits the user perfectly.
