Hayabusa's final maneuver, a three-hour "firing" of its ion thrusters to fine-tune the spacecraft's trajectory toward Australia, was successful.

The Hayabusa spacecraft is about to die. On Sunday, June 13, at 14:00 UTC, Hayabusa will burn up in Earth's atmosphere, bringing its dramatic seven-year mission to an end.

Hayabusa's mission team has successfully shifted the little spacecraft's approach trajectory from the day side to the night side of Earth, a critical maneuver for the survival of the sample return capsule.

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.
