The International Space Station has been the victim of an incident that forced the American crew to take refuge in the Russian segment of the station, where astronauts are safe. The Russian space agency has reported initially of an ammonia leak, after a cooling circuit, but NASA does not confirm yet.
This incident is likely in any case to delay the return to Earth of the Dragon capsule of the US company SpaceX, which recently refueled the ISS, where live six astronauts, two Americans, three Russians and one Italian.
On his Twitter account, NASA indicates that the alarm has been triggered by a pressure spike, a defective sensor or a computer problem.
