OSIRIS-REx continued outbound cruise operations this last week. On the ground, members of the navigation team worked through the results of a Navigation Training Exercise (NTE) test on asteroid shape modeling. The test was designed to demonstrate the team’s readiness to perform landmark optical navigation techniques during asteroid proximity operations. This means the team would be able to navigate the spacecraft using Bennu’s landmarks as a guide instead of using star fields. Landmark navigation provides more precise and timely information on the spacecraft’s location around Bennu, which improves mission safety and efficiency.
