Leaks are affecting a key part of the International Space Station. NASA and Russia’s space agency, Roscosmos, are not seeing eye to eye about the level of risk.

A recent report out last month from NASA’s Office of the Inspector General highlighted some of the big challenges to keeping the ISS flying safely until 2030.

Students from Colorado will have the opportunity to hear NASA astronauts Nick Hague and Suni Williams answer their prerecorded questions aboard the International Space Station on Thursday, Nov. 14.

The station has been leaking air for five years, and NASA is concerned that this might indicate a potential failure in the structural integrity of the International Space Station.

NASA and Russian officials disagree on the cause of a worsening leak on the ISS, raising safety concerns for astronauts.
