Mars rover leaving crater after yearlong probe
Tue Aug 26, 6:32 PM ET
PASADENA, Calif. - The plucky Mars rover Opportunity is driving out of a giant
crater nearly a
year after a dangerous descent to examine exposed bedrock.
NASA said Tuesday that engineers noticed a power surge in Opportunity's left
front wheel
and decided to pull it out of the crater before it got stuck. Its twin rover,
Spirit, lost function
in its right front wheel in 2006 after a similar surge.
Opportunity descended into Victoria Crater last September and inspected bright
rock layers.
Once it emerges, it will study loose rocks on the equatorial plains.
