Space shuttle Discovery launched just before midnight Friday on a mission to the international space station. The crew of seven astronauts includes one from Mexico and another from Sweden. One of those seven, Nicole Stott, will remain on the station as a flight engineer, while astronaut Timothy Kopra is to return home aboard the shuttle.
NASA on Thursday put off the planned launch of the space shuttle Discovery for a third time to give engineers more time to study tests on a liquid hydrogen valve, the space agency announced. The shuttle’s liftoff — originally set for Tuesday — has been put off until 11:59 p.m. Friday, mission managers said.
