Black HRSI (high-temperature reusable surface insulation) tiles are an integral component of the Space Shuttle orbiter's thermal protection system. This system shields the vehicle from the destructively searing heat of re-entry into the atmosphere and also provides passive thermal control in orbit. About 23,000 black tiles cover the entire underside of the vehicle, as well as portions of the vertical tail, wings, and forward and aft fuselage where temperatures reach 1,200-2,300 degrees F (650-1,260 degrees C). This tile was removed from the left nose landing gear door after being damaged on the first flight of Columbia in 1981. NASA transferred a number of such tiles to the Museum after the STS-1 mission.
