A resupply mission to the International Space Station will have to wait on some repairs.
Astronauts at the International Space Station continue to try to fix part of a cooling system that shut down last Wednesday. And that may mean putting off a rocket launch from Wallops Island, Va., scheduled for Thursday.
The unmanned rocket would hoist a cargo ship with supplies for the international space station, and its launch has already been put off a couple of days due to the cooling system problem.
The problem comes down to a bad valve at the space station, which has shut down half of the cooling system.
NASA has been trying to regulate the temperature using a different valve — with some success.
But two Americans on board the space station may need to make spacewalking repairs beginning Thursday, when the rocket is set to take off.
NASA will decide today or tomorrow whether to postpone the launch — while astronauts continue their repairs.
