Deep Impact in trouble: last heard from August 8

A terse update on the status of the aging Deep Impact spacecraft was posted on the mission website this morning:
We have not received any of our expected observations of comet ISON due to a spacecraft problem. Communication with the spacecraft was lost some time between August 11 and August 14 (we only talk to the spacecraft about once per week). The last communication was on August 8. After considerable effort, the team on August 30 determined the cause of the problem. The team is now trying to determine how best to try to recover communication.
As long as controllers are communicating with a spacecraft, there is hope. When they are not in communication with a spacecraft, that's pretty scary. Good luck to the Deep Impact team on recovering the spacecraft for a future comet or asteroid encounter. It's a great little mission.

There was a stage set up on the steps of the administration building, and the quad in front of it was filled with JPLers of all ages and descriptions. Rick Grammier and Don Yeomans introduced the band -- five guys, all members of the band since 1953 or earlier, still rockin' and rollin'.

"Our cratering experiment went very very well," reported impact scientist Peter Schultz in what may have been the understatement of the weekend. A first look at early science results from the mission suggest that while some events unfolded according to scientists' predictions, Tempel 1 provided many enticing surprises as well.

Here in Von Karman auditorium at JPL, as they get ready for the press conference, they are playing "Rock Around the Clock," by Bill Haley and His Comets. Very appropriate! The press panel is mostly familiar: Andy Danztler, Rick Grammier, Shyam Bhaskaran, Mike A'Hearn, and Pete Schultz.

The Deep Impact mission seems to have produced an impact crash beyond the expectations, but not the hopes, of the science team.

The panel consists of: Andy Danztler, Solar System Division Director at NASA HQ; Rick Grammier, Deep Impact Project Manager, JPL; Jennifer Rocca, Deep Impact Systems Engineer, JPL; and Mike A'Hearn, Principal Investigator, University of Maryland.

I woke this morning to find a press release in my Inbox that said: "One hundred and seventy-one days into its 172-day journey to comet Tempel 1, NASA's Deep Impact spacecraft successfully released its impactor at 11:07 p.m. Saturday, Pacific Daylight Time," or 06:07 UTC.

NASA's Deep Impact spacecraft is set for its date with Comet Tempel 1. "We are going to hit a bullet with another bullet while watching from a third bullet," said Charles Elachi, the head of JPL.
