It has been awhile since I posted anything to this site. The launch of OSIRIS-REx was such an amazing, emotional experience; it took me about a month to come back down to Earth (pun intended). I have now settled into a normal work routine in Tucson and the team has been busy operating the spacecraft and planning for the encounter with Bennu in 2018. We are now in the Outbound Cruise phase of the mission.

We Have a Healthy Spacecraft
Outbound Cruise began soon after the spacecraft separated from the Atlas V launch vehicle as planned. The spacecraft post-separation activities were all nominal and the spacecraft quickly transitioned to the “Outbound Cruise” operating mode. I studied the separation video quite a bit and noticed what appeared to be a plume originating from the lower portion of the spacecraft. After talking with the spacecraft engineers, we realized that the out-gassing was the result of the initialization of the propulsion system. This out-gassing was also evident in the DSN tracking data since we could see small forces slightly changing the spacecraft trajectory.
