Deep Impact in trouble: last heard from August 8

Posted by Emily Lakdawalla

Topics: mission status, Deep Impact

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.

Tip of the hat to Amy Mainzer.

Today the Deep Impact/EPOXI science team held a press briefing that followed up on their very successful flyby of two weeks ago, a status report on what they can say so far about the science that's coming out of the encounter.

In which I finally write up last week's Deep Impact Hartley 2 press briefing

Posted by Emily Lakdawalla on 2010/11/09 01:13 CST

On Thursday, November 4, at 13:50 UTC, Deep Impact flew within 700 kilometers of comet Hartley 2. Hartley 2 is the smallest and most active of the five comets that have been directly by a spacecraft, and the first to be visited within the lifetime of its discoverer.
