STS-75 crew insignia

STS075-S-001 (September 1995) --- The STS-75 crew patch depicts the space shuttle Columbia and the Tethered Satellite connected by a 21-kilometer electronically conducting tether. The orbiter/satellite system is passing through Earth?s magnetic field which, like an electronic generator, will produce thousands of volts of electricity. Columbia is carrying the United States Microgravity pallet to conduct microgravity research in material science and thermodynamics. The tether is crossing Earth?s terminator signifying the dawn of a new era for space tether applications and in mankind?s knowledge of Earth?s ionosphere, material science, and thermodynamics. The patch was designed for the STS-75 crew members by Mike Sanni. The NASA insignia design for space shuttle flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the forms of illustrations by the various news media. When and if there is any change in this policy, which is not anticipated, the change will be publicly announced. Photo credit: NASA
