Deep Impact's last images

Today I received an email notification of new public releases of some image data sets. I always love seeing new public space image data, but this notification was bittersweet: it included the first public release of the very last image data returned to Earth by Deep Impact, of a distant comet ISON.

Deep Impact in trouble: last heard from August 8

Communication with the Deep Impact spacecraft was lost some time between August 11 and August 14. The team has determined the cause of the problem, and is trying to figure out how to restore communication.

Interplanetary eyes on the lookout for comet ISON

Space blogger Daniel Fischer provides a preview of the exciting interplanetary observing campaign that has recently begun to study comet C/2012 S1 (ISON) from vantage points across the solar system.

Pretty picture: a moon transit

A reader comment inspired me to dig up an oldie but a goodie: a sequence of photos of the Moon transiting Earth, seen from a very long way away,

What's up in the Solar System in August 2012

Welcome to the monthly roundup of our solar system's envoy of electronic explorers! All eyes are on Curiosity as it approaches Mars this weekend. Who will lend support at the Red Planet?

A little fun with Deep Impact deep-sky data

Last week, the team put all of the data from Deep Impact's deep-sky imaging session online, and challenged visitors to see what they could make from it. I made some photos of M51, but there were some challenges.

Brief notes from Day 2 of the DPS-EPSC meeting

It's been a very full day at the DPS-EPSC 2011 joint meeting. My day was less full than it might have been, because I overslept and missed most of the morning's session. I really needed the rest though so I think it was probably for the best!

What's up in the solar system in April 2011

April 2011 will see MESSENGER begin the science phase of its orbital mission at Mercury, and should, I think, also see the start of Dawn's approach observations of Vesta. At Mars, Opportunity is back on the road again, rolling inexorably toward Endeavour. At Saturn, Cassini will continue its focus on Saturn and Titan science.

LPSC 2011: Day 3: Deep Impact at Hartley 2

Wednesday's sessions at the Lunar and Planetary Science Conference (LPSC) on the Deep Impact flyby of Hartley 2 were one of two that I was most looking forward to, the other being this morning's talks on Hayabusa's samples from Itokawa, about which I don't yet have any notes. I am again grateful to Franck Marchis and Andy Rivkin for sending me their notes on Hartley 2.

What's up in the solar system in March 2011

I don't think there's any question what the big event of this month will be: MESSENGER is finally, finally entering orbit at Mercury on March 18 at 00:45 UTC (March 17 at 16:45 for me).
