I've gotten this question about once a week since Spirit got stuck, but yesterday, two different readers asked the same question within an hour of each other, so I figured it was time for a blog entry.

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.

Each Titan flyby is not a fork in the road, but rather a Los Angeles style cloverleaf in terms of the dizzying number of possible destinations. So how did our current and future plans for the path of the Cassini spacecraft come to be? That's the question Dave Seal put to me since that's my job -- I am a tour designer.

I was delighted to receive an email from Morten Bo Madsen, who I knew from the Mars Exploration Rover mission as "that Danish magnet guy," the fellow responsible for the magnet experiments on nearly every American Mars mission. The magnets were originally designed to study the properties of airborne Martian dust, which would help determine its composition.

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.

"What plays in Potsdam stays in Potsdam" - that's how Ralph described a problem I mentioned over at UMSF where I explained I couldn't combine the audio of my talk with the MOV of the slides because you're not allowed to record presentations. It's "law of the stag" for conferences. So, in the spirit of the law, here's an overview of Ralph's excellent overview of Titanian geology as seen by various RADAR passes.

Earth's radio astronomers have saved the day for one of the Huygens instrument teams. Today, the Doppler Wind Experiment (DWE) team announced their first science results, despite losing nearly all of their expected data.
