According to media reports, the domestic Rocket and Space Corporation Energia has formulated requirements, the implementation of which will reduce the risk of emergency situations on Soyuz spacecraft in the event that they receive holes when colliding with space debris or micrometeorites. The result of the work done by RSC Energia specialists was presented on the pages of the scientific and technical journal “Space Equipment and Technologies”.
The main ideas for ensuring safety in the process of eliminating accidents that occur as a result of depressurization due to the formation of holes in the plating of transport ships are as follows:
- providing spacecraft and the ISS with tools for detecting leaky areas,
- training of crew actions in case of depressurization of the ISS,
- approval of a ban on the organization of transit lines laid through the hatch between the ship and the adjacent compartment (the ban does not apply to quick-release air ducts, as well as the clamps that connect the active and passive docking units).
Let us recall that on August 30 last year, the ISS crew discovered an air leak on the Soyuz MS-09 spacecraft. An American ultrasonic device was used to detect the hole in the casing. It is worth noting that even then the cosmonauts assumed that the hole in the casing was made with a drill, but Roscosmos put forward the official version, according to which the hole was formed as a result of a collision with a micrometeorite. Later, the ship's crew managed to patch the hole using a special repair compound. The investigation into the appearance of a hole in the skin of the Soyuz MS-09 spacecraft is still ongoing.
