In the Russian Federation, proceedings are continuing on the fact of depressurization of one of the blocks of the Soyuz spacecraft. According to preliminary data, it was found that the hole in the skin was made from the inside using a drill. This is evidenced by the characteristic scratches from the device, which worked in zero gravity.
Now it became known that the Russian cosmonauts will go into outer space in mid-November this year. This event was planned, however, in addition to the standard inspection procedures, the need to study the nature of the damage from the outside will be added to the exit.
Thus, it will be possible to more accurately determine the cause of the hole. If negligence was committed during manufacture, then sealant residues should remain in the casing. If the hole is made with a drill, then characteristic burrs will be found. The complexity of the work lies in the fact that the household compartment of the Union was not intended for external work.
Recall that among the versions of depressurization are negligence during production, as well as deliberate damage to the skin by American astronauts. The relevant commission calls on all interested parties to wait until the end of the official investigation of this issue.
