Japanese Spacecraft Ready To Land on Asteroid Nov. 12

Peter de Selding writes in Space.com:

Japan’s Hayabusa asteroid sample-return satellite is scheduled to make the first of two landings on its target asteroid Nov. 12 following ground controllers’ conclusion that it has enough fuel to finish its job despite the loss of two of its three reaction wheels, the Japanese space agency, JAXA, announced Oct. 31.

Under current planning, a second touchdown would occur Nov. 25 before Hayabusa, whose name was Muses-C before its May 2003 launch, begins a return flight to Earth. Since Sept. 12, the satellite has been stationed several kilometers from the Itokawa asteroid, which is some 300 million kilometers from Earth.

Hayabusa lost the use of its first reaction wheel in July. The second failed Oct. 3, forcing increased reliance on the chemical-propellant thrusters to maintain satellite attitude control.
