Abstract : The DebriSat tests were conducted to better understand the distribution of fragments generated from a hypervelocity impact with a modern satellite. The last such test (SOCIT) was conducted 20 years ago and satellite construction has changed considerably since then. DebriSat was a NASA program with support/collaboration from the Air Force Space and Missile Center, University of Florida and Aerospace. It consisted of three tests: Pre Preshot, Debris-LV and DebriSat. Tests were conducted at the Arnold Engineering Development Complex Range G Two-Stage Light Gas Gun Facility with a pressure of 1-2 Torr of air and using approximately 600 gram projectiles with nominal velocities of 7 km/s. The Pre Preshot target was a multi-shock shield supplied by NASA designed to catch the projectile. It consisted of seven bumper panels consisting of fiberglass, stainless steel mesh and Kevlar. Debris-LV used a 15 kg target fabricated by Aerospace to simulate a spent upper stage. DebriSat consisted of a 50 kg target constructed by the University of Florida from materials representative of a modern LEO satellite.
