Opportunity Takes a Last Look at Rock Exposure Before Heading to 'Victoria Crater'
NASA's Mars Exploration Rover Opportunity recently stopped to analyze an
exposure of rock near "Beagle Crater," on a target nicknamed "Baltra."
Nearly 100 sols, or Martian days, had passed since Opportunity had last
analyzed one of the now-familiar rock exposures seen on the Plains of
Meridiani. The rover ground a 3-millimeter-deep (0.12-inch-deep) hole in
the rock using the rock abrasion tool on sol 893 (July 29, 2006) while
stationed about 25 meters (82 feet) from the southwest rim of Beagle
Scientists wanted to analyze the outcrop one more time before driving the
rover onto the ring of smooth material surrounding "Victoria Crater."
Opportunity's analysis showed the rock to be very similar in its elemental
composition to other exposures encountered during the rover's southward
trek across Meridiani Planum.
Opportunity acquired the image data shown here shortly after noon on Mars
on sol 896 (Aug. 1, 2006) with the panoramic camera (Pancam), after
backing up 1 meter (3.3 feet) from Baltra to assure that the target was
in sunlight. This is an approximately true-color Pancam image, generated
from mathematical combinations of calibrated left-eye images using filters
ranging from 432-nanometer to 753-nanometer wavelengths.
