NASA鈥檚 Deep Space 1 spacecraft has returned to its senses and is on course
for a rendezvous with a comet. The spacecraft lost its bearings in November when
its star-tracking camera failed. Last month, engineers beamed software to Deep
Space 1 that allowed it to orientate using its science camera
(麻豆传媒, 27 May, p 19).
The spacecraft is now firing its thrusters on
course for Comet Borrelly, which it should reach in September 2001. 鈥淭his rescue
is one for the history books,鈥� says project manager Marc Rayman of NASA鈥檚 Jet
Propulsion Laboratory.
