The iPad 2 will officially be the first tablet computer in space, as two units have already been stowed in the Progress 45 cargo craft along with three tons of food, water, oxygen, gear and fuel. Progress 45 sits atop a Soyuz booster at Baikonur Cosmodrome in Kazakhstan, awaiting launch early Sunday morning. Astronauts at the International Space Station (ISS) will have the option of using the iPad 2 devices for entertainment when off duty.
Additional tablets will likely join the iPads in space next year, as NASA is still evaluating different models. The ISS already has two iPhone 4 units and several iPods on board, the latter was first introduced in 2005 for music listening in space. The Progress 45 mission is unmanned, however in November a three-man crew is set to travel to ISS on a Soyuz TMA-22.
