For the first and only time in the history of the American space program, a previously aborted mission is flown with the same vehicle, cargo and crew. Space Shuttle Columbia returns to orbit with Spacelab in its cargo bay for an attempt to fully carry out the aborted STS-83 mission, which was recalled to Earth in April. This time, the mission is successful, with nearly 16 days of microgravity experiments carried out by the crew. Flying Columbia – again – are Commander James Halsell, Pilot Susan Still, Payload Commander Janice Voss, mission specialists Donald Thomas and Michael Gernhardt, and payload specialists Roger Crouch and Greg Linteris.
