STS-101 was a Space Shuttle mission to the International Space Station (ISS) flown by Space Shuttle Atlantis. The mission was a 10-day mission conducted between 19 May 2000 and 29 May 2000. The mission was designated 2A.2a and was a resupply mission to the International Space Station. STS-101 was delayed 3 times in April due to high winds. STS-101 traveled 4.1 million miles and completed 155 revolutions of the earth and landed on runway 15 at Kennedy Space Center. The mission was the first to fly with the "glass cockpit".
Cosmonauts Yuri I. Malenchenko and Boris V. Morukov, along with astronaut Edward T. Lu were moved to STS-106. Astronauts James S. Voss and Susan J. Helms, and cosmonaut Yury V. Usachev were added to the STS-101 crew. Malenchenko, Morukov and Usachev all represent the Russian Space Agency (RSA).
There are at least 3 variations of the STS-101 patch:
Internal wingtip (the wingtip is inside the oval of the patch)
External wingtip (the wingtip extends beyond the oval of the patch)
"Banded" - the red, white and blue dither is a banded stitch
This STS-101 patch is a bit of an enigma. It is slightly smaller than the common souvenir version and has a distinct banding of the bottom red, white and blue striping where the others are "notched". It does not appear to be a limitation of the stitching, as the rest of the patch bears identical detail on the ISS modules as the larger versions. This version appears on eBay infrequently and I would classify this as "scarce".
