Alan read the following information on the NASA website while researching for a report on Mars.
NASA's senior Mars rover, Opportunity, is examining rocks at the edge of
Endeavour Crater for signs that they may have been either transported
by a flood or eroded in place by wind.
Those scenarios are among the possible explanations rover-team
scientists are considering for features seen just outside the crater rim's
crest above "Perseverance Valley," which is carved into the inner slope of
the rim.
The team plans to drive Opportunity down Perseverance Valley after
completing a "walkabout" survey of the area above it. The rover's drives
now use steering motors on only the rear wheels, following a temporary
jam of the left-front wheel's steering actuator this month. Opportunity has
not used its right-front wheel's steering actuator since 2005, the year
after it landed on Mars.
The mission has been investigating sites on and near the western rim of
Endeavour Crater Since 2011. The crater is about 14 miles (22
kilometers) across.
