Lost In Space

 

Oh bother, looks like a mistake during a down link hand off from one ground station to another resulted in the robotic lander Minerva to be dropped at the wrong time. Hayabusa (it’s shadow is visible on the above photo, cool eh?) had been making burns to keep station over the asteroid Itokawa when the lander was commanded to release. The spacecraft was moving away at a speed of 15cm/sec, 2cm/sec faster than the asteroids escape velocity. So, Hayabusa launched Minerva into space. That sucks, I was looking forward to seeing that hop around on the surface. However, all is not lost. The laser range finder system on Hayabusa is working great, the thrusters are working pretty well to keep correct orientation, and plans for the slug to be shot into Itokawa is still on the short list of planned events.

The Hydromechanical Cochlea

 

 This is getting close to an actual replacement for human hearing, it can detect sounds but it can’t do anything with the information. Also, the frequency range (4200-35,000 Hz) passes human hearing (20-20000 Hz). Still it is a major step closer to a hearing implant that could restore the hearing of thousands of people.

Hayabusa Nearing Itokawa

 

Hayabusa Mission

The Japanese mission to land a 10cm high robot names ‘Minerva’ on an asteroid is still on track even if the spacecraft is not in the best of health. Three of its four reaction wheels (devices used to maintain correct orientation) have failed and is now using precious propellant to stay on target.

Itokawa

 

The images that are being sent back are stunning. The survey of asteroid Itokawa is sure to produce a wealth of data on solar objects.

I’m looking forward to seeing if the tiny rover will be able to stay on the surface for any length of time or if it will bounce off and float away. If everything works as planned this will be the fist controlled landing and exploration of an asteroid in the history of mankind.
