Reentry Breakup Recorder: Concept, Testing, Moving Forward
Michael, Weaver, et al. (2012). "Reentry Breakup Recorder: Concept, Testing, Moving Forward." AIAA SPACE 2012 Conference & Exposition
Decommissioned satellites and spent rocket states routinely reenter the atmosphere from low-Earth and low-perigee orbits. Though seldom recovered, debris of significant size and mass survive to gourd impact. Reentry survivability models are intended to predict these hazards in advance of launch and reentry, but models have tended to under-predict the survivability, relative to observable data and recovered debris. In order to improve and validate models, a growing need developed for more information on the environment and response of unprotected reentering bodies. The Aerospace Corporation conceived a new device that would collect ate during the reentry and breakup of a satellite or launch stage, would protect the data through the severe heating and loading phases, would break away as the host vehicle disintegrated and would transmit the recorded data before ground impact, eliminating any need for hardware retrieval. The Reentry Breakup Recorder (REBR) was successfully flight tested in 2011 during reentry for the Japanese HTV2 supply vehicle form the International Space Station. An overview is provided in the motivation of REBR, its design the data from the HTV2 flight test, the future evolution of REBR, and the technology transition approach.
