My collage of all the asteroids and comets visited by spacecraft is probably the single most popular image I have ever posted on this blog. I've now updated it to be in color and to include Toutatis.

When Hayabusa's sample return capsule was first opened and found to be very clean-looking inside, I doubted that there could be enough material for laboratory analysis. JAXA announced later that they scraped about 1500 dust grains from the inside with a teflon spatula, and these likely came from Itokawa.

I'd been despairing of finding a good source for a writeup of the presentations in the Hayabusa session at last week's Lunar and Planetary Science Conference, but am happy to report that I've finally found an excellent one.

Upon James Aldridge's return from Japan, he posted several albums worth of amazing photos, including several of their calligraphy instructor, well-known artist Aiko Tanaka, creating a gestural brush painting to commemorate Hayabusa's return.

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.

Hayabusa is still 100 million kilometers from the Earth, less than an astronomical unit away but still with months to travel. But according to an update posted to their websitethis morning by project manager Junichiro Kawaguchi, Hayabusa is on the home stretch.

Trouble has come time and again to JAXA's little Hayabusa asteroid sample return mission, yet the mission's engineers always come up with new and creative ways to solve problems.

JAXA issued a press release (in Japanese) on November 9 stating that one of Hayabusa's ion thrusters, thruster D, had stopped operating. Hayabusa launched with four ion thrusters, but D was one of only two that are still functioning. So the failure of thruster D is a serious problem.

Today, I'm kicking the week off with a look at the unusually intense confluence of far flung planetary exploration that's just around the corner, starting the middle of next year.

JAXA has posted a note on their website on the status of Hayabusa, which apparently reached aphelion in late May. Hayabusa is Japan's amazing ion-powered mission to asteroid Itokawa, which touched down on Itokawa to grab a sample in mid-November 2005, but suffered an injury that has left in doubt its ability to return the sample capsule to Earth.
