Thermal Protection Systems
A thermal protection system or TPS is the barrier that protects a spacecraft during the searing heat of atmospheric reentry. A secondary goal may be to protect the spacecraft from the heat and cold of space while on orbit. Multiple approaches for the thermal protection of spacecraft are in use, among them ablative heat shields, passive cooling and active cooling of spacecraft surfaces.

Famous quotes containing the words protection and/or systems:
“Guns have metamorphosed into cameras in this earnest comedy, the ecology safari, because nature has ceased to be what it always had been—what people needed protection from. Now nature tamed, endangered, mortal—needs to be protected from people.”
—Susan Sontag (b. 1933)
“The geometry of landscape and situation seems to create its own systems of time, the sense of a dynamic element which is cinematising the events of the canvas, translating a posture or ceremony into dynamic terms. The greatest movie of the 20th century is the Mona Lisa, just as the greatest novel is Gray’s Anatomy.”
—J.G. (James Graham)
