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.

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.

There's a new Planetary Society contest: "Are We There Yet? -- Measuring Stardust's Cosmic Journey." How far do you think Stardust will have traveled to get to Tempel 1? Guess here and get a chance to win a cool T-shirt!

A new update has been posted to the Stardust website: The spacecraft continues to operate as expected and all subsystems are healthy on approach to comet Tempel 1.

A press briefing was held at NASA Headquarters this morning to preview the planned February 14 encounter by Stardust with Tempel 1. There aren't often lots of questions from media after these "preview" briefings, but today there were zero. That's not good.

Today the 365 Days of Astronomy podcast aired my contribution, Unmanned Space Exploration in 2011, about what to look forward to in solar system exploration this year.

Stardust is healthy after performing a "cold boot" to clear a memory address problem (a "memory address latch-up") that occurred late last year and caused the spacecraft to go into safe mode three times.

Two brief but significant news items today made me stop and think about how far we've come in space travel.

Here's the five close-approach images of Hartley 2 captured today, November 4, 2010, by the Deep Impact spacecraft, collected into one file. Boy, do these images reward close examination!

While we don't have Moon bases, we do have plenty of spacecraft. Before I get into my more detailed look at the activities of the 20-odd spacecraft wandering about the solar system, I thought I'd look ahead to 2010 more generally and see what the year has in store for us.

Remember how Hayabusa was virtually still for 30 minutes? JAXA is now saying that Hayabusa actually touched down -- and more than that, they may even have a sample.
