Russian cosmonauts are scheduled to perform a spacewalk outside the International Space Station (ISS) on Tuesday, December 11, to investigate a “mysterious” hole that caused an air leak.
NASA originally stated that the 2mm wide hole was caused by chance from a passing micro meteoroid or orbital debris strike, however it then transpired that the hole was caused by a drill and was then patched up shoddily.
According to Rocosmos chief Dmitry Rogozi sabotage has not been ruled out.
