Who Caused The Mysterious Leak At The International Space Station?

A 2-millimeter hole was found last week in a Russian Soyuz MS-09 spacecraft (left) that is docked to the International Space Station.

“We don’t reject any theories,” said Dmitry Rogozin, the head of Russia’s space agency. That includes sabotage, though he suspects it was more likely a “technological error.”
