On Dec. 29 and 31, the OSIRIS-REx spacecraft successfully completed the two maneuvers required to enter orbit about Bennu. The accurate performance of these orbit insertion maneuvers, as well as the continued accurate navigation performance since orbit insertion, allowed for the wave-off of several planned updates to the spacecraft’s orbit determination (OD). The mission’s navigation team will continue to study OD performance over the first few weeks of spacecraft orbits to further refine and predict orbital operations – which will eventually allow the team to reduce the trim burn schedule.

The first orbit of Bennu, which started on Dec. 31, ended 61.4 hours later on Jan. 3. The spacecraft will continue orbiting the asteroid through mid-February.
