OSIRIS-REx / OSIRIS-APEX Spacecraft System
The Lockheed Martin-built OSIRIS-REx spacecraft collected samples from asteroid Bennu and delivered its return capsule to Earth in 2023. The surviving spacecraft was renamed OSIRIS-APEX and remains active on an extended mission to rendezvous with asteroid Apophis in 2029. NASA lists a 2,110 kg fueled launch mass and a 6.2 m length with solar panels deployed, 2.43 m width, and 3.15 m height; these values describe the spacecraft envelope and do not treat the released sample capsule or TAGSAM arm as separate vehicle dimensions. Its integrated hydrazine propulsion subsystem remains the same surviving spacecraft installation after the OSIRIS-REx-to-OSIRIS-APEX rename.

- Variant Notes
- Integrated 28-thruster OSIRIS-REx/OSIRIS-APEX system: MR-107S main, MR-106L TCM, MR-111G ACS, and MR-401 low-thrust groups; same surviving spacecraft after OSIRIS-REx sample-capsule release and rename to OSIRIS-APEX.
- Name
- OSIRIS-REx / OSIRIS-APEX integrated propulsion installation
- Notes
- The continuing spacecraft's hydrazine propulsion subsystem contains four MR-107S main engines, six MR-106L trajectory-correction thrusters, sixteen MR-111G attitude-control thrusters, and two MR-401 low-thrust reaction-engine-assembly thrusters. The relationship records one whole-subsystem installation; the component model families, counts, and mission functions remain in the propulsion identity and notes.
