It's a hit!

PASADENA -- Wild applause and cheering in the control room, as they not only get confirmation of the impact, but an immediate and "awesome" image of a spray of debris from the impact, captured just 3.7 seconds after the hit.
"Geez, and we thought it was going to be subtle," exulted JPL scientist Don Yeomans, as pandemonium erupted in the mission control room.
"If this doesn't make the front page, something is really wrong," he added as the amazing first impact image appeared on the screen.
