Astronauts at the International Space Station are working to repair a small leak that was discovered at the orbiting laboratory Wednesday night (Aug. 29). While the leak caused a slight drop in cabin pressure, it did not pose an immediate danger to the astronauts currently living aboard the station, NASA officials said.
Flight controllers on Earth began to notice changes in cabin pressure around 7 p.m. EDT (2300 GMT), while the six crewmembers of Expedition 56 were sleeping, NASA officials said in a statement today (Aug. 30).
Because the pressure loss was "very small," flight controllers determined that the astronauts and cosmonauts "are in no danger," officials with the European Space Agency (ESA) said in a separate statement
