On Dec. 20, the mission transitioned into Outbound Cruise sub-phase 5, which is the final sub-phase of Outbound Cruise operations. To mark the transition, the spacecraft returned to using the +X Low Gain Antenna (LGA) for its communications back to Earth. The spacecraft had previously been communicating over the –X LGA.
The next mission operations transition will be into Approach Phase, which begins Aug. 17, 2018, when the spacecraft is approximately 2 million km from Bennu.
