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.

JAXA has released a 30-minute video of the Hayabusa mission, "Return of the Falcon," combining computer animation with actual footage of the construction and launch as well as images from the spacecraft of Itokawa.

If I understand the various sources(and my somewhat vague memory) correctly, it now appears that Earth has rotated far enough to take the Deep Space Network station at Goldstone, through which Hayabusa has been transmitting, out of line with Hayabusa.

Hayabusa reached an altitude of about 560 meters above Hayabusa at 17:30 UTC. And at 18:00 UTC they are at 500 meters. This is still farther above the asteroid than the asteroid is big...there is still a long way to go before Hayabusa touches down...

In a further update on Hayabusa's status, we have been contacted by Kazuya Yoshida of the Space Robotics Laboratory at Tohuku University. Yoshida reports that the touchdown is now planned to take place "in early morning of November 20 (Sunday) JST", which would make it late Saturday evening UTC, or Saturday midday here in California.

The Hayabusa mission has proven to be a bit of a tease -- they were releasing lots of images to the public as they approached asteroid Itokawa, but once they arrived, the image releases shut down entirely. There is finally a little postage stamp of an image captured by Hayabusa at "home position," only 7 kilometers from the asteroid, compared here to a picture taken from "gate position," 20 kilometers away.
