TSX-5 / Pegasus XL
Called TSX-5 for short, the 12-sided satellite carries a host of experiments incorporated within two distinct payloads: the Space Technology Research Vehicle-2 (STRV-2) and the Compact Environmental Anomaly Sensor (CEASE). STRV-2 is a $43 million research effort sponsored by the Ballistic Missile Defense Organization featuring a half-dozen experiments from both the United States and United Kingdom. The second payload, CEASE, is a warning system of sorts that will detect electrically-charged particles and radiation in the area around the satellite, which can be harmful to the craft. The Air Force Research Laboratory sponsors the $4 million CEASE.
