- April 8, 1993, 1:29:00 a.m. EDT. First launch attempt on April 6
halted at T-11 seconds by orbiter
computers when instrumentation on
liquid hydrogen high point bleed valve in
main propulsion system
indicated off instead of on. Later analysis indicated valve was properly
configured; 48-hour scrub turnaround procedures implemented. Final
countdown on April 8 proceeded smoothly. Payload up weight: 16,046 lbs.
Orbiter Weight Empty: 173,227 lbs. Orbiter
weight at liftoff: 236,659 lbs.
- Altitude: 160nm

- April 17, 1993, 7:37:19 a.m. EDT. Runway 33,
Kennedy Space Center. Fla.
Rollout distance: 9,529 feet (2,904 meters). Rollout time: 62 seconds.
Landing originally set for April 16 at KSC waved off due to weather. Second
reefing line added to drag chute for greater-stability. Landing Weight:
206,855 lbs. Payload down weight 16,046 lbs.
Last Mission STS-54
- Primary payload of flight was Atmospheric Laboratory for Applications
and Science-2 (ATLAS-2), designed to collect data on relationship
between sun's energy output and Earth's
middle atmosphere and how
these factors affect ozone layer. Included six instruments mounted on
Spacelab pallet in cargo bay, with seventh mounted on wall of bay in
two Get Away Special canisters. Atmospheric instruments were
Atmospheric Trace Molecule Spectroscopy (ATMOS) experiment;
Millimeter Wave Atmospheric Sounder (MAS); and Shuttle Solar
Backscatter Ultraviolet/A (SSBUV/A) spectrometer (on cargo bay wall).
Solar science instruments were Solar Spectrum Measurement
instrument; Solar Ultraviolet Irradiance Monitor
(SUSIM); and Active
Cavity Radiometer (ACR) and Solar Constant
- ATLAS-2 is one element of NASA's Mission to Planet
Earth program. All
seven ATLAS-2 instruments first flew on ATLAS-I during
will fly a third time in late 1994.
- On April 11, crew used remote manipulator arm to deploy Shuttle Point
Autonomous Research Tool for Astronomy-201
free-flying science instrument platform designed to study velocity
and acceleration of solar wind and observe sun's corona. Collected
data was stored on tape for playback after return to Earth.
SPARTAN-201 retrieved on April 13.
- Crew also made numerous radio contacts to schools around world using
Shuttle Amateur Radio Experiment II
(SAREX II), including a brief
radio contact with Russian Mir space station, first such contact
between Shuttle and Mir
using amateur radio equipment.
- Other cargo bay payloads: Solar Ultraviolet Experiment
sponsored by Colorado Space Grant Consortium, and located in Get Away
Special canister on cargo bay wall.
- Middeck payloads: Commercial Materials Dispersion Apparatus
Instrumentation Technology Associates Experiment
Physiological and Anatomical Rodent Experiment
(PARE); Space Tissue
Cosmic Ray Effects and Activation Monitor (CREAM)
experiment; Hand-held, Earth-oriented, Real-time, Cooperative,
User-friendly, Location-targeting and Environmental System
Radiation Monitoring Equipment III
(RME III); and Air
Force Maui Optical Site (AMOS) calibration test.
