- 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.

- 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:

- 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 (SOLSPEC)
instrument; Solar Ultraviolet Irradiance Monitor (SUSIM); and Active
Cavity Radiometer (ACR) and Solar Constant (SOLCON) experiments.
- ATLAS-2 is one element of NASA's Mission to Planet Earth program. All
seven ATLAS-2 instruments first flew on ATLAS-I during STS-45, and
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 (SPARTAN-201), a
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 (SUVE),
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 (CMIX);
Physiological and Anatomical Rodent Experiment (PARE); Space Tissue
Loss (STL-1); Cosmic Ray Effects and Activation Monitor (CREAM)
experiment; Hand-held, Earth-oriented, Real-time, Cooperative,
User-friendly, Location-targeting and Environmental System
(HERCULES); Radiation Monitoring Equipment III (RME III); and Air
Force Maui Optical Site (AMOS) calibration test.
