L-0 - 9:08:52.775 LIFTOFF of GRAIL atop a Delta II 7920H-10 headed to study the moon!
As you can see from above, GRAIL finally made it off the ground on the 6th launch window and my last chance as my plane left several hours after liftoff.
It was a rocky road to launch but GRAIL made it off the ground. Everything has performed flawlessly since. Fingers crossed it will stay that way.
Orbital insertion for GRAIL-A and GRAIL-B on December 31 and January 1, respectfully.
