The unmanned Hayabusa spacecraft, launched in May 2003, will become the first spacecraft to bring asteroid material to Earth when it lands in Woomera, South Australia, later this year.'"

Is that Meatloaf has significant input into some of the software that went into that space craft. Say what you want about his music (its shit) but the guy has made many important contributions to both the Linux kernel and also more academic code as this. The guy deserves more credit!

Anyone catch the doomsday paragraph at the end FTFA:
''If we're on a collision course with an asteroid we need to know if they are rock-solid or if they are piles of rubble,'' he said. ''That will help us predict how best to deal with them.''
...how many sinister space asteroid scares have we had in the past decade claiming utter calamity on the earth? I''m not claiming conspiracy theory on this one (so stay in your caves, trolls!) but it'll be cool to see what kind of composition and materials are uncovered on that thing; because it would be good to know. It's nice to get good, "rock" solid evidence to back up a lot of theories and guessed accuracies of our solar system that are mostly data interpreted facts and not visual or tangible.

Oh, physical rocks. I thought at first this was about Acid Mothers Temple, the other Japanese Space Rock.

The more we can do without sending humans to do it in person, the faster exploration will progress.

Last time I heard, the japanese had lost contact with the spacecraft when it was near the asteroid after MAYBE taking samples. They had given up and declared the mission a failure. I must've missed something here.

A plucky little space probe (Score:4, Interesting)
There have been *so* many technical problems with this mission, such as failure of reaction wheels, loss of the rover during deployment, damage to the solar cells by a flare, loss of attitude and communications due to a fuel leak, and so on. The mission timeline [wikipedia.org] reads like "And then this broke, and we managed to fix it. And then this, and we fixed that. And ..." Yet they are getting close to pulling off the main goals of the mission (sample return). A failure of the sampling procedure probably means they've got a bit of dust rather than the larger pieces they were hoping for, but it's better than nothing! And the pictures and other data the probe has returned are very cool [isas.jaxa.jp]. The asteroid is a "rubble pile", which had been speculated for many asteroids, but not directly seen before.
The engineers and scientists that are running the mission deserve a lot of credit for keeping this thing going despite the problems (the contractors that built it, not as much :-)).
Might have Asteroid Samples on It (Score:5, Interesting)
The most fascinating part about this mission, however, was the fact that it was using four plasma thrusters to steadily propel it to its destination. To my knowledge, this is the first time such technology has been used as the primary propulsion source for a mission. Even more fascinating is that three of the four thrusters failed and, as of now, one functioning thruster is a jury rigged hack job that they got working by using the control systems from one failed thruster and the thruster and propellant from a second. That said, Hayabusa has been an absolute testament to the tenacity and creativity in problem solving of JAXA. It has been an exciting mission, and I am very much looking forward to finding out just how lucky the unlucky probe has been in collecting dust bits from the asteroid.

There is no actual guarantee that there is a sample in the chamber (as the pellets misfired).
It's a remarkable achievement to get it back; let's hope that there is something inside.

Yes, you missed a lot. They recovered it and are getting back, after a real "Perils of Pauline" type adventure.

Being a high-tech field and competitive field, musicians are always in the need of the cutting edge. Quite a few musicians have either directly or indirectly contributed to kernel or application code, either through paying for development or getting right down and coding it themselves. The Meatloaf code may or may not have been actually coded by him, though that is how people like to say it.
The other high-tech artist's field is movie production, and they contribute code as well.
