Last Mission STS-35
Next Mission STS-39
- Primary payload, Gamma Ray Observatory
(GRO), deployed on
flight day three. GRO high-gain antenna failed to deploy on command;
finally freed and manually deployed by Ross and Apt during
unscheduled contingency space walk, first since April
day, two astronauts performed first scheduled space walk since November
1985 to test means for astronauts to move themselves and equipment about
while maintaining planned Space Station Freedom.
GRO science instruments
were Burst and Transient Source Experiment (BATSE), Imaging Compton Telescope
(COMPTEL), Energetic Gamma Ray Experiment Telescope (EGRET) and Oriented
Scintillation Spectrometer Experiment (OSSEE). Secondary payloads
included Crew and Equipment Translation Aids
(CETA), which involved
scheduled six-hour space walk by
astronauts Ross and Apt (see above);
Ascent Particle Monitor (APM); Shuttle Amateur Radio Experiment II
Protein Crystal Growth (PCG); Bioserve/instrumentation Technology Associates
Materials Dispersion Apparatus (BIMDA); Radiation Monitoring Equipment III
(RME Ill); and Air Force Maui Optical Site
