NAME The Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) Spacecraft
TYPE Spacecraft
DESCRIPTION The OSIRIS-REx spacecraft is a roughly cubic shape, 2.4m x2.4m x3.15m, with two solar panel wings extending from opposite sides. Launch mass including propellant was 1529 kg. Propulsion uses 200 N hydrazine thrusters mounted at the base of the spacecraft. Primary communication is via a 2 meter high gain directional dish antenna. The spacecraft carried a sample return capsule, which was filled at asteroid (101955) Bennu, carried back to Earth by the spacecraft, and delivered to the surface in Septermber 2023. The OSIRIS-REx spacecraft was then redeployed to the asteroid (99942) Apophis for an extended mission to investigate that potentially hazardous body.
