STS-59 crew insignia
The STS-59 insignia is dominated by Earth, reflecting the focus of the first Space Radar Laboratory (SRL-1) mission upon our planet's surface and atmosphere. The golden symbol of the astronaut corps emblem sweeps over Earth's surface from the Space Shuttle Endeavour, representing the operation of the SIR-C/Synthetic Aperture Radar (X-SAR) and the Measurement of Air Pollution from Space (MAPS) sensors. The astronaut emblem also signals the importance of the human element in space exploration and in the study of our planet. The star field visible below Earth represents the many talents and skill of the international SRL-1 team.
