Just arrived at my destination! Time to initiate the back-away burn 🔙

Next rehearsal, I’ll keep descending and perform a third maneuver (the Matchpoint burn) before backing away. For the actual TAG event, I’ll keep going until I touch Bennu’s surface and collect a sample. pic.twitter.com/JuZn6bLDhw

One way or another, I'm gonna find ya

This is a 4 hour event, and I'm moving at an average speed of approximately 0.2 mph (0.3 kph) relative to Bennu. (Or about the speed of a tortoise 🐢)

I'll provide updates as each event of the rehearsal sequence occurs.
