The first commercial resupply mission to the International Space Station is set to lift off from the Kennedy Space Center Sunday evening. From the space station crew's standpoint, some of the most precious cargo could well be ice cream.
The space shuttle Endeavour landed in California on its way to its final resting place. On the way, it made a flyover in Tucson, Arizona where former Congresswoman Gabrielle Giffords and her husband Mark Kelly, Endeavour's retired commander, were watching.
'I'm happy to be done,' Williams said from the International Space Station Sunday after she crossed the orbital finish line. 'It wasn't easy, and I'm sure everybody in California's very happy to be done too.'
Williams first launched into space in 2007 and spent 195 consecutive days in space, setting a record for the longest single spaceflight by a female astronaut. On Wednesday, she'll celebrate her birthday in space.
