Continue exploring Mars and learn about asteroids in this video of class 6 of Bruce Betts' Introduction to Planetary Science and Astronomy class.
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.

The Hayabusa update is brief: having opened the first Hayabusa sample return chamber (compartment A) last month, JAXA has now opened compartment B, and they found nothing inside.

Since I posted an update Monday about JAXA confirming extraterrestrial samples in the Hayabusa sample return capsule, JAXA has posted an English-language version of their press release, which contains a bit more information.

It's official: in a press release today, JAXA announced that some 1,500 dust grains scraped from the interior of Hayabusa's clean-looking sample return capsule are not of terrestrial origin so must be from Itokawa.

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!

Today the 365 Days of Astronomy podcast aired my contribution, The Flight of Hayabusa, a recap of that dramatic mission.

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.

Covering the events of Hayabusa's return involved a lot of watching and waiting. Rather than go blind staring at my computer and cause carpal tunnel syndrome by excessively clicking the refresh button, I decided to...go blind and develop carpal tunnel syndrome by doing some crocheting.

Here are a few photos from a Flickr gallery from the Australian Science Media Centre documenting the Hayabusa sample capsule's first step in its journey from Australia to Sagamihara, Japan, where it will arrive on Friday.

The major news on the Hayabusa mission this morning is that JAXA has retrieved the sample capsule!

Oh my wonderful little flying saucer, you have been to an asteroid and back -- and you were burning like a star last night! And there you are, sitting quietly in the desert, just waiting to be retrieved...
