Red Mars
NASA’s Spirit rover is now a-ramblin’ on the surface of Mars.
Spirit was to have taken less than two minutes to travel the 10 feet from the unfolded petals of its lander onto Mars. Engineers said the move likely would be the riskiest of Spirit’s entire three-month mission.Engineers delayed the move for three days to give Spirit time to reposition itself atop its lander, where it had sat since arriving. Spirit had to turn in place 115 degrees to line up with one of the exit ramps that ring the lander.
Originally, Spirit was to roll straight off the lander on its ninth day on Mars. But the now-deflated air bags that cushioned the rover’s Jan. 3 landing blocked that way, forcing Spirit to perform a slow pirouette, turning clockwise in three separate moves.
Mission plans called for Spirit to spend several days parked beside its lander after rolling off, giving it time to find its bearings and perform some preliminary analysis of the soil and rocks around it.
NASA then planned for Spirit to begin a meandering trip in the direction of an impact crater about 825 feet away. Spirit was designed to travel dozens of yards a day.
