An air leak on the International Space Station might have been sabotage, according to the head of Russia’s Roscosmos space agency, and an investigation is under way.



Dmitry Rogozin said the hole detected last Thursday in a Russian Soyuz module docked at the ISS was caused by a drill and could have been done deliberately, either back on Earth or by someone in orbit.

“There were several attempts at drilling,” Rogozin said late on Monday in televised comments, adding that the drill appeared to have been held by a “wavering hand”.

“What is this: a production defect or some premeditated actions?” he asked. “We are checking the Earth version. But there is another version that we do not rule out: deliberate interference in space.”

Astronauts used tape to seal the leak after it caused a small loss of pressure that was not life-threatening.



A state commission would seek to identify the culprit by name, Rogozin said, calling it a “matter of honour” for Russia’s Energiya company that makes the Soyuz.



Asked for comment on allegations of possible sabotage, a Nasa spokeswoman referred all questions to the Russian space agency which is overseeing the commission’s analysis.

Rogozin had initially said the hole in the side of the ship used to ferry astronauts was most likely caused from outside by a tiny meteorite, but later admitted that had been ruled out.

First thought was MMOD strike.



Then NASA released pics. Lots of people: "Hmmm, doesn't look like MMOD". NASA deleted the photos.

A Russian MP who is a former cosmonaut suggested that a psychologically disturbed astronaut could have done it to force an early return home. “We’re all human and anyone might want to go home, but this method is really low,” said Maxim Surayev, who is from President Vladimir Putin’s ruling party.

“If a cosmonaut pulled this strange stunt – and that can’t be ruled out – it’s really bad,” said Surayev, who spent two stints on the ISS.

“I wish to God that this is a production defect, although that’s very sad too – there’s been nothing like this in the history of Soyuz ships.”

Alexander Zheleznyakov, a former space industry engineer and author, told the TASS state news agency that drilling the hole in zero gravity would be nearly impossible in that part of the spacecraft.

“Why would cosmonauts do it?” he asked.

The hole is in a section of the Soyuz ship that is discarded in orbit and not used to carry people back to Earth.

A space industry source told TASS the spacecraft could have been damaged during testing at Baikonur cosmodrome in Kazakhstan after passing initial checks and the mistake then hastily covered up. “Someone messed up and then got scared and sealed up the hole,” the source speculated, but then the sealant “dried up and fell off” when the Soyuz reached the ISS.

Energiya will carry out checks for possible defects on all Soyuz ships and Progress unmanned ships used for cargo at its production site outside Moscow and at Baikonur, RIA Novosti has reported, citing a space industry source.

The ISS is one of the few areas of Russia-US cooperation that remains unaffected by the slump in relations and Washington’s sanctions.

Russia’s rockets used for launching spacecraft and satellites have suffered engine problems.

Currently on the ISS are two cosmonauts from Russia, three Nasa astronauts and a German from the European Space Agency.
