Complex Mars rover rolls facing long and risky delay
Pasadena AP The six wheeled Spirit sits 16 inches above Mars dust as engineers wrestle with a complex unfolding sequence to roll it onto the surface delaying wheels down until at least Wednesday or Thursday. The air bags and a 115 degree pirouette route dominate a process longer than NASA expected and raising concerns about potential damage before the twin Opportunity arrives. Spirit’s first steps to unfold should take about 75 seconds after landing on January 3. The Sojourner rover of 1997 stands as the only prior Mars rover.
