A "Black Box" For Space Debris?

jonerik writes: "Space.com has this piece on engineers at El Segundo's Aerospace Corporation, who are trying to create a black box - similar to those used in civilian, commercial, and military aircraft - for satellites and other pieces of equipment bound for space, with the aim of trying to figure out why certain pieces of space debris survive reentry largely intact while others burn up in the atmosphere. The box - about the size and shape of a paperback book - would sit dormant perhaps for years and reactivate when a thermal switch senses the temperature rising, signalling reentry. 'Loaded with ultra-small sensors, including accelerometers and a Global Positioning System navigation chip, the box would record the stresses and strains on the hardware during its fall from space.'"
