Space Shuttle Challenger - Flown LRSI Tile Fragment

Above: Front of the Specimen Card featuring NASA image STS07-32-1702. Taken on June 22, 1983, during STS-7. The Space Shuttle Challenger (OV-099) was the second of the space shuttles in the program to enter orbit, embarking on its maiden voyage on April 4, 1983. Over the course of its ten missions, the shuttle gathered scientific data, repaired satellites, and brought the first African-American to space, Guion Bluford. This specimen is a mission-flown tile fragment from the Space Shuttle Challenger. Known as a low-temperature surface insulation tile (LRSI), the tile is comprised of low-density silica. The tiles protected parts of the orbiter exposed to temperatures in excess of 1,200°F and below 0°F. Above: Space Shuttle Challenger LRSI Tile with typical NASA scrap tags. Each tile was unique, specifically designed to meet the exact shape, weight, and temperature resistance required at its location on the craft. NASA disposition paperwork received with this item indicates this particu
