Here it is, the first image from Stardust of Tempel 1 during the close-approach phase!

I really didn't expect these images to look so good! I'd prepared myself for blurry images and a lot of squinting to try to match up features in pictures between Deep Impact and Stardust views of Tempel 1, but in fact the resemblance is obvious and you can clearly see that they successfully imaged the area in which Deep Impact's Impactor craft collided with the comet.

Just a brief update on the Stardust flyby of Tempel 1, which happened about half an hour ago: the spacecraft seems to have executed the flyby as commanded and has 72 science images on board.

Stardust is very close to the last major act of its mission: the flyby of Tempel 1, which will take place at 20:40 PST (04:40 UTC). Here's a summary of the recent and current status of the mission, and how to follow the events over the next 24 hours.

I dug around and found something unique: this cool heart-shaped feature on Mars -- my Valentine to you all!

We're coming up on the final days of Stardust's approach to Tempel 1. The flyby takes place on February 15 at 04:56 UTC (February 14 at 20:56 PST).

NASA announced that the Planetary Society’s LightSail 1 solar sail mission is on their short list for upcoming launch opportunities. The missions selected are CubeSats destined for piggyback launches as part of NASA's CubeSat Launch Initiative.

Thanks to the work of several amateurs, Google Mars is a great tool for following the past and future peregrinations of the Mars Exploration Rover Opportunity.

Last week we got buzzed by a very small asteroid, something that happens fairly often. But there were several details that made the close approach of asteroid 2011 CQ1 worthy of note.

There is a huge storm that's spreading across so much of Saturn that it's been readily visible even from Earth-based telescopes. Over the past couple of days a couple of new images of Saturn have appeared that show just how enormous the storm is today.

Here's a neat paper just published in Geophysical Research Letters:

Here's some links to some good followup stories on Wednesday's Kepler press briefing.

Today Mars made its closest approach to the Sun -- as seen from Earth, that is. Why is this important?

The Rosetta blog has been strangely quiet of late, after they had been quite actively posting updates on the status of Rosetta during a critical series of orbit adjustment burns, which I wrote about two weeks ago.

Welcome to my monthly roundup of what's happening with our deep-space explorers across the solar system. I apologize for its lateness; two sick kids have drastically affected my productivity this week, but they're better and now I'm getting back to work.

Dawn continues its flight through the asteroid belt, steadily heading toward its July rendezvous with Vesta, where it will take up residence for a year. On January 10, Dawn performed some of the activities that it will execute in its low altitude mapping orbit (LAMO) at Vesta.

I wasn't able to watch the Kepler press briefing today so I will give you links to some of my favorite blogs for information on today's announcement, which follows a major data release last night as well as the publication of a paper in Nature.

I was very fortunate to be able to meet with Stephen Hawking and Buzz Aldrin over lunch at Hawking's temporary home in Pasadena this week. We got together to discuss views on the future of human space exploration.

Now that Stardust has images of its target comet to work with, the mission was able to figure out their relative positions more precisely, and they've gone ahead with an important rocket firing that shifts the spacecraft's aimpoint past the comet closer to the number that they want.
