NASA's Twin Spacecraft on Final Approach for Moon Orbit

GRAIL-A is just now slipping into lunar orbit.

GRAIL-B will be arriving tomorrow, New Year's Day, about 2 pm PST.

Then the fun begins. Studying the Moon inside and out. This is simply wonderful stuff.

It's making me want to work on Revisitor. It'll come. Other writing projects are more pressing.
