STS-91 / Discovery Patch

Item PASTS091 Price $4.95

This was the twenty-fourth Discovery flight. STS 91 marked the final Shuttle/MIR Docking Mission. This Phase 1 Program is a precursor to the International Space Station maintaining a continuous American presence in space and developing the procedures and hardward required for an international partnership in space. Carried the Alpha Magnetic Spectrometer Investigation (AMS) to search for anti-matter and dark matter in space and to study astrophysics. First use of the super lightweight external tank (SLWT), same size as previous but 7,500 lbs. lighter. This will provide additional payload capacity to the International Space Station. Brought Thomas (arrived MIR on STS 89)back from MIR. Landed at Kennedy Space Center, FL. June 12, 1998. Mission Duration: 9 days 19 hours 55 minutes and 1 second.

Patch description: This is the crew patch for the STS-91 mission -- the ninth flight of the Shuttle-Mir Phase One docking missions. The crew will bring back Andrew S. W. Thomas, the last long-duration American crew member flown on the Russian Space Station Mir. This mission marks the end of the Shuttle-Mir Phase One Program and will open the way for Phase Two: construction of the International Space Station (ISS). The crew patch depicts the rendezvous of the Space Shuttle Discovery with the Space Station Mir. The flags of the United States and Russia are displayed at the top of the patch and both countries are visible on the Earth behind the two spacecraft. The names of the American crew members surround the insignia on the outer areas, with the name of cosmonaut Valeriy Ryumin in Cyrillic at the lower right. The Alpha Magnetic Spectrometer (AMS) is an international payload planned to fly in the payload bay of Discovery. Two thin golden streams flowing into the AMS represent charged elementary particles. The detection of antimatter in space will help scientists better understand the physics and origins of the universe.

4" diameter embroidered patch.
