STS061-S-088 (2 Dec 1993) --- The Space Shuttle Endeavour lifts off from Launch Pad 39B with a crew of six NASA astronauts, a Swiss mission specialist and a variety of special tools aboard. Launch occurred at 4:27:00 a.m. (EST), December 2, 1993. The seven member crew will team to perform a variety of service tasks on the Hubble Space Telescope (HST). Four of the group will break into pairs on alternating sessions to carry out a total of five days Extravehicular Activity (EVA). Onboard are astronauts Richard O. Covey, Kenneth D. Bowersox, F. Story Musgrave, Kathy C. Thornton, Jeffrey A. Hoffman and Thomas D. Akers, along with Swiss scientist Claude Nicollier.

KENNEDY SPACE CENTER, FLA. -- Members of the STS-104 crew practice using tools they will work with on their mission. The crew is at KSC to take part in Crew Equipment Interface Test activities. Seen are (from left) Pilot Charles O. Hobaugh and Mission Specialist Michael L. Gernhardt. Also among the crew are Commander Steven W. Lindsey and Mission Specialists Janet L. Kavandi and James F. Reilly. The mission will carry the Joint Airlock Module to the International Space Station. The U.S.-made module will allow astronauts and cosmonauts in residence on the Station to perform future spacewalks without the presence of a Space Shuttle. The module, which comprises a crew lock and an equipment lock, will be connected to the starboard (right) side of Node 1 Unity. Atlantis will also carry oxygen and nitrogen storage tanks, vital to operation of the Joint Airlock, on a Spacelab Logistics Double Pallet in the payload bay. The tanks, to be installed on the perimeter of the Joint Module during the mission’s spacewalks, will support future spacewalk operations and experiments plus augment the resupply system for the Station’s Service Module
