SUMMARY: Just 48 hours after launch, NASA's Spirit spacecraft was 5.6 million kilometres away from Earth and on track for Mars. Just after launch, Spirit was rotating 12.03 times a minute and then thrusters on board reduced this to 2 rotations a minute. As the spin rate slowed down, the star scanners on Spirit were able to recognize various constellations and plot its position. The next hurdle will be when Spirit performs a trajectory-correction maneuver sometime soon. Spirit will arrive at Mars on January 4, 2004.
