What's up in the solar system in January 2010

Posted by Emily Lakdawalla on 2010/01/04 01:29 CST

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 stumbles on the path back to Earth

Posted by Emily Lakdawalla on 2009/11/11 11:19 CST

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.

Hayabusa update

Posted by Emily Lakdawalla on 2008/06/01 11:48 CDT

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.

Thruster trouble for Hayabusa

Posted by Emily Lakdawalla on 2005/11/29 08:59 CST

Hayabusa has been riding an incredible wave of luck lately, resulting in the dramatic success of the sample grab last week. But it looks as though Hayabusa's luck may be running out.

A gap in the Hayabusa telemetry, as the Earth rotates

Posted by Emily Lakdawalla on 2005/11/19 01:02 CST

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.

Closer still to Itokawa

Posted by Emily Lakdawalla on 2005/11/19 08:46 CST

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...

Getting ready for Hayabusa's touchdown

Posted by Emily Lakdawalla on 2005/11/18 01:40 CST

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.

Amazing Hayabusa images

Posted by Emily Lakdawalla on 2005/11/10 09:36 CST

These photos pretty much speak for themselves. They are amazing. Hayabusa saw its own shadow on Itokawa, and took a photo of the released target marker.

A piece of a new picture from Hayabusa

Posted by Emily Lakdawalla on 2005/10/04 06:21 CDT

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.
