Rock Spire in 'Spirit of St. Louis Crater' on Mars
Jet Propulsion Laboratory
April 30, 2015

An elongated crater called "Spirit of St. Louis," with a rock spire in
it, dominates a recent scene from the panoramic camera (Pancam) on NASA's
Mars Exploration Rover Opportunity.

Opportunity completed its 4,000th Martian day, or sol, of work on Mars
on April 26, 2015. The rover has been exploring Mars since early 2004.

This scene from late March 2015 shows a shallow crater called Spirit of
St. Louis, about 110 feet (34 meters) long and about 80 feet (24 meters)
wide, with a floor slightly darker than surrounding terrain. The rocky
feature toward the far end of the crater is about 7 to 10 feet (2 to 3
meters) tall, rising higher than the crater's rim.

The component images of this mosaic view were taken on March 29 and 30,
2015, during Sol 3973 and Sol 3974 of the mission. This version of the
image is presented in approximate true color by combing exposures taken
through three of the Pancam's color filters, centered on wavelengths of
753 nanometers (near-infrared), 535 nanometers (green) and 432 nanometers
(violet).

The view is centered toward the northeast. The rover's location and the
Spirit of Saint Louis Crater are near the center of a map at:

The unusually shaped Spirit of St. Louis Crater lies on the outer portion
of the western rim of Endeavour Crater. Endeavour spans about 14 miles
(22 kilometers) in diameter, and Opportunity has been exploring its western
rim for about one-third of the rover's mission, which has lasted more
than 11 years. Endeavour's elevated western rim extends northward to the
left from Spirit of St. Louis Crater in this scene. A glimpse of the far
side of Endeavour is visible on either side of the rock spire.
