Space Shuttle Endeavour - Flown Thermal Blanket

Above: Front of the Specimen Card The Space Shuttle Endeavour (OV-105) was the final of the orbiters to be built, replacing the Challenger shuttle. Named for Captain James Cook’s HMS Endeavour, the shuttle’s career included the first repair mission for the Hubble Space Telescope and the addition of the Unity Module to the ISS, the first American addition to the space station. The Endeavour also flew Mae Jemison, the first African American woman in space. This specimen is a piece of insulation blanket that was part of Endeavour’s Thermal Control System. The TCS helped the ship withstand the extreme increase in temperatures during atmospheric reentry and the TCS blanket was applied to the inside of the shuttle to protect internal components and systems. Softgoods such as the blanket were a simple and efficient way to provide lightweight insulation to delicate items. NASA disposition paperwork received with this item indicates this particular blanket was removed after STS-99 which flew on 02/11/2000, which was this shuttle’s last solo mission. As pictured below, each hand-cut specimen is housed in an acrylic jar and ships in a classic, glass-topped riker display case. The specimens measure roughly 1x1cm though variations may occur. A small information card is also included, which serves as the certificate of authenticity. Special Handling Notice: It's very important to note that this was a multi-layer insulation blanket so we've elected to provide multiple layers with each specimen. All specimens will have a layer of aluminized Kapton foil and a layer of fibrous bulk material. It's also possible that there may be a fragment of the Dacron net separator, but we've tried to remove that as it is quite brittle. In any case, if you choose to open the specimen jar, take great care. The Kapton is very light and slightly brittle with age and use. It may fly away or even break into smaller pieces. More about Space Shuttle Program and Endeavour (OV-105) After the close of the Apollo program, NASA turned its focus from lunar landings to research and observation. The vessel for this new focus would be the Space Shuttle, a multi-use vehicle designed to carry astronauts and scientific equipment to and from Earth's orbit. Due to their reusable design, the orbiters were amazing tools for furthering our scientific understanding of the stars.  NASA's Space Shuttle program delivered 133 successful missions during its three decades in operation, beginning with Columbia's inaugural mission in 1981 and concluding with Atlantis' in 2011. Missions involved many vital tasks, such as maintaining the International Space Station, repairing the Hubble Space Telescope, and deploying satellites. Scientific experiments featured heavily in the rotation, using the reusable Spacelab developed by the ESA.  As noted above, the Space Shuttle Endeavour was the final of the orbiters to be built, replacing the Challenger shuttle. As a cost-saving measure, much of the shuttle was built from leftover parts from the other orbiters. Named for Captain James Cook’s HMS Endeavour, the shuttle’s career included the first repair mission for the Hubble Space Telescope and the addition of the Unity Module to the ISS, the first American addition to the space station. The Endeavour also flew Mae Jemison, the first African American woman in space. Over its active years, Endeavour orbited Earth 4,671 times, traveling approximately 120 million miles. The shuttle weighed about 156 thousand pounds, boasting a wingspan of about 80 feet and a length of about 120 feet. Endeavour can now be seen at the California Science Center, where it is open for display to the public. Further Reading Lamoreux, James C., James D. Siekierski, and JP Nick Carter.
