5/21/93: JUNE 3 AS TARGET DATE FOR NEXT SHUTTLE MISSION
STS-57 LAUNCH ANNOUNCEMENT

KSC RELEASE: 57 - 93
NASA managers today set June 3, 1993 as the target date for the next
flight of the Shuttle system. The mission, designated as STS-57, will see
Space Shuttle Endeavour and her six person crew conduct a mission highlighted
by the retrieval of the European observation satellite EURECA and the first
flight of a commercial spacelab facility known as Spacehab.
The June 3 date is based on successful completion of work in progress to
understand the cause of a noise/vibration event experienced during launch pad
processing.
The launch window on June 3 opens at 6:17 p.m. EDT and extends for 1 hour
and 11 minutes. The limited launch window time is based on EURECA retrieval
requirements. The mission duration is planned for 7 days. However, it may be
extended by 1 day immediately after launch if projections calculated at that
time for electrical power consumption permit an extra day in space. The extra
day will give two members of Endeavour's crew the opportunity to perform an
extravehicular activity (EVA) or spacewalk.
The STS-57 EVA will be the second in a series of spacewalks designed to
refine training methods and expand the EVA experience level of astronauts,
flight controllers and instructors. The STS-57 spacewalk also will assist in
refining several procedures being developed to service the Hubble Space
Telescope on Shuttle Mission STS-61 in December.
Leading the STS-57 crew will be Mission Commander Ronald Grabe. Pilot for
the mission is Brian Duffy. Heading up the science team will be Payload
Commander David Low who is also designated as Mission Specialist-1. The three
other mission specialists for this flight are Nancy Sherlock (MS-2), Jeff
Wisoff (MS-3) and Janice Voss (MS-4).
This will be the fourth flight of Space Shuttle Endeavour and the 56th
flight of the Space Shuttle system.
