SOAREX-VI
Sub-Orbital Aerodynamic Re-entry EXperiments VI (SOAREX-VI) was sponsored by the Hypersonics Project within the Fundamental Aeronautics Program of NASA, and developed by NASA's Ames Research Center. It was carried by the ALV X-1 as a secondary payload. SOAREX-VI would have attempted to characterize an innovative self-orienting reentry vehicle shape called the Slotted Compression RAMP (SCRAMP) probe. The SOAREX-VI package also included an atmospheric density calibration probe built by NASA Ames in cooperation with the University of Idaho, and an AIS probe built by the United States Naval Research Laboratory (NRL).
After detonation of the rocket, the SOAREX-VI enclosure inside was broken open. The SCRAMP probe, designed to activate upon ejection, did exactly that and acquired two TDRSS satellites overhead and an S-band tracking dish on land. It transmitted sensor and video data until it was destroyed on splashdown.
