A Reentry Breakup Recorder (REBR) is a device that is designed to be placed aboard a spacecraft to record pertinent data when the spacecraft (intentionally) breaks up as it re-enters Earth's atmosphere. The device records data regarding the thermal, acceleration, rotational and other stresses the vehicle is subject to. In the final stages it transmits the data back to a laboratory before it is destroyed when it hits the surface.
