STS-78

Space Shuttle Columbia lifts off on the 78th shuttle mission, a Spacelab flight lasting nearly 17 days and devoted to the effects of microgravity on various forms of life. The crew also tests maneuvers under consideration for a future Hubble Space Telescope servicing mission which could safely boost Hubble’s orbit without damaging it. Aboard Columbia for her 20th flight are Commander Terence Henricks, Pilot Kevin Kregel, flight engineer Susan Helms, mission specialists Richard Linnehan and Charles Brady, and payload specialists Jean-Jacques Favier and Robert Thirsk.
