Last week, Roscosmos Space Corporation head Dmitry Rogozin said an air leak and subsequent drop in pressure occurred at the Soyuz spacecraft docked to the International Space Station (ISS). The ISS crew managed to cope with the problem. On Monday, Rogozin told reporters that the special commission was checking whether there was a deliberate drill impact on the Soyuz spacecraft's skin.
“The commission, which continues to investigate causes of the incident, tends to believe that the hole in the habitation module of the Soyuz spacecraft was made during construction of the spacecraft in the assembling facility,” one of the sources said.
The third source noted that the hole could not have been drilled when the spacecraft was docked to the ISS as such works could not have been made without a special procedure involving many experts.
