Lauretta:  Low data rate for now, then download images from the high gain antenna overnight.

Final slew coming up! This time I'll rotate to repoint the TAGSAM arm and navigation cameras toward Bennu's surface. Getting ready for touchdown. #ToBennuAndBack

The OSIRIS-REx spacecraft has steered to the proper orientation for final descent to Bennu, with its 11-foot-long sampling arm and cameras pointed toward the asteroid's surface.

For the next ~6 minutes, I'll move my solar panels into the Y-wing configuration. This positions the panels up and away from the asteroid's surface so that I can touch down safely.

One interesting thing from the NASA TV OSIRIS-REx event (besides the fact the spacecraft's approach is going as planned): NASA personnel are wearing masks with transparent sections; Lockheed staff wearing black fabric masks with the mission logo. Life in 2020.

The OSIRIS-REx Camera Suite, or OCAMS, instruments have started their descent imaging sequence. The cameras will capture imagery throughout the final descent and the touch and go landing.

We are now in the Y-wing configuration ✅

Almost ready for the Checkpoint burn to start the steep descent toward the surface. First the NFT system will predict my position & speed at the time of the Checkpoint & Matchpoint burns, make any necessary trajectory corrections & then I'll get the green light for the first burn

Checkpoint burn complete

For the next 10 minutes, I'll descend more steeply toward Bennu's surface... then it'll be time for the Matchpoint burn! #ToBennuAndBack

Next up - Matchpoint burn! This maneuver changes my flight path to match Bennu's spin, allowing me to precisely target site Nightingale and safely touch down on the surface.

The Matchpoint burn is complete 🔥 ✅  and I'm approximately 131 ft (40 m) over the surface! I'll descend for another 10 mins and then it's TAG time! #ToBennuAndBack

Mission control reports OSIRIS-REx's attitude control system has transitioned to touch and go mode. The spacecraft is currently 141 feet, or 43 meters, from Bennu.

🔥 Matchpoint Burn completed. "We've got about 10 minutes before contact with the asteroid surface." @OSIRISREx is maneuvering to match the speed and spin of asteroid Bennu before its final descent to the surface. #ToBennuAndBack

Just passed the 25 m crossing. It's almost time 😲

The final navigation report from mission control indicates OSIRIS-REx is heading for a safe touch and go landing zone with a 0% chance of hazards.
