A hole found in a spacecraft module docked on the International Space Station is now believed to have been drilled.
The latest theory suggests that someone who is present on the space station may have drilled the hole, while another theory is that it was drilled before the module was launched towards the ISS.
The hole was discovered on Aug. 29 when mission control in Moscow and Houston detected a non-life threatening drop in pressure. Russian officials said the spacecraft could have run out of air within 18 days if left undetected.
Maxim Surayev, a politician and retired cosmonaut, told the state-run RIA Novosti news agency that it may have been done by a psychologically disturbed astronaut.
The crew found the hole and patched it with a rubber plug made from garbage bag seals, duct tape, medical gauze, and vacuum-proof sealant, The Telegraph reported.
The hole was drilled in a Russian Soyuz module, on a piece that gets discarded in space, not a part used to transport people back to Earth, The Guardian reported. It nonetheless has an effect on astronauts aboard while it is docked at the ISS.
At least one Soyuz stays attached to the space station at any one time. It acts as an emergency pod if people needed to leave the space station and return to Earth. The Soyuz launches and lands in Kazakhstan, according to NASA.
One space industry source thinks the hole could have been created there, during testing, Phys.org reported.
“Someone messed up and then got scared and sealed up the hole,” the source told TASS, speculating that the sealant “dried up and fell off” when the module reached the ISS.
The head of Russia’s Roscosmos space agency, Dmitry Rogozin, said that a state commission expects to find out who drilled the hole and name him or her publicly.
“There were several attempts at drilling,” Rogozin said in televised comments, according to The Guardian, adding that the drill seems to have been held by a “wavering hand.”
