International crew takes off for space station

NASA launched four astronauts to the International Space Station on Friday and the astronauts will replace a crew that returned from the station early due to a medical issue with one of its members.

NASA declined to disclose any details about the health issue that cut the previous mission short. The pre-dawn launch was delayed by two days over adverse weather forecasts across the US East Coast and the astronauts are expected to arrive at the ISS on Saturday.
