A scheduled spacewalk by two Russian cosmonauts docked on the International Space Station (ISS) was cancelled after the discovery of an unexplained leak coming from the Soyuz MS-22 spacecraft, according to NASA.

Live Footage captured a snow-like fluid spewing out of the space capsule, which was identified by NASA as a coolant leak.

All seven members of the ISS crew are reportedly not in any significant danger, and all systems of the space station are functioning normally, confirmed Russian space agency Roscosmos Thursday morning in a statement to Twitter.

“The crew reported that the warning device of the ship’s diagnostic system went off, indicating a pressure drop in the cooling system,” stated Roscosmos. “A visual inspection confirmed the leak, after which it was decided to interrupt the planned extravehicular activities by the crew members of the ISS Russian Segment Sergey Prokopyev and Dmitry Petelin.”

The leak was first noticed when Russian cosmonauts Petelin and Prokopyev were transferring a radiator from one module to another on the Soyuz MS-22, according to reports. Shortly after transmitting images of the leak to NASA headquarters, the scheduled spacewalk was aborted.

NASA commentator Rob Navias said the implications of the leak are “unknown and the effect at this point unknown as Russian managers continue to look over the data and consult with both NASA managers and engineers.”

The next steps for the Soyuz MS-22 have not yet been determined.

“NASA and Roscosmos will continue to work together to determine the next course of action following the ongoing analysis,” said NASA in a statement Thursday.

Five additional spacecraft are stationed at the ISS, which orbits around 250 miles above Earth.
