Cracks have been spotted on the International Space Station, and while it isn’t cause for immediate concern, retired NASA astronaut and current member of NASA’s ISS Advisory Committee Bill Shepherd described it as a “fairly serious issue.”
NASA told Business Insider the cracks do not threaten the safety of astronauts at this time and no new potential leak sites were found.
The cracks were found by Russian cosmonauts on the Zarya module back in August. Eerily enough, no one seems to understand why the cracks are appearing. To add to the unsettling news, Shepherd believes there may be cracks the crew hasn’t discovered yet.
