Rover: Opportunity Date: November 4, 2004

A close-up look at the surface of a rock called "Wopmay," inside "Endurance Crater," shows crevices and spherical concretions. The view combines four frames taken by the Microscopic Imager on Opportunity during the rover’s 259th sol (Oct. 15, 2004). Evidence from the rover’s spectrometers and Microscopic Imager is consistent with the possibility that rocks near the bottom of the crater were affected by water both before and after the crater formed. The evidence is still not conclusive. The area shown is about 6 centimeters (2.4 inches) across.

Rover: Opportunity Date: October 18, 2004

Opportunity’s Pancam camera took a close look at the unusual, lumpy rock informally named "Wopmay" on the lower slopes of "Endurance Crater." The rock’s informal name refers to Wilfrid Reid "Wop" May, a Canadian bush pilot. Scientists believe that the lumps in Wopmay, like traits of "Escher" and other rocks dotting the bottom of Endurance Crater, may be related to cracking and alteration processes, possibly caused by exposure to water. The area between intersecting sets of cracks appears to have eroded in a way that shaped the lumpy appearance.

Rover: Opportunity Date: October 7, 2004

An approximate true-color view of the rock dubbed "Wopmay" in "Endurance Crater." The rock was named after the Canadian bush pilot Wilfrid Reid "Wop" May. Like other rocks dotting the bottom of Endurance, scientists believe the lumps in Wopmay may be related to cracking and alteration processes, possibly caused by exposure to water.

Rover: Opportunity Date: September 30, 2004

At the upper left of this Pancam image is a bizarre, lumpy rock nicknamed "Wopmay" which is located on the inner slopes of "Endurance Crater." In coming sols, Opportunity will make its way toward the interesting rock. Scientists say the rock’s unusual texture is unlike any other observed so far at Meridiani Planum. Wopmay measures approximately 1 meter (3.3 feet) across. This image was taken by the rover’s panoramic camera on sol 195 (Aug. 11, 2004).

Rover: Opportunity Date: September 21, 2004

As Mars emerges from behind the Sun, Opportunity is inside the stadium-sized "Endurance Crater," headed toward the base of a stack of exposed rock layers in "Burns Cliff," and a potential exit route on the crater’s south side. This map shows the rover’s complete traverse through its 205th martian day, or sol (Aug. 21, 2004). The rover stopped driving for two weeks during solar conjunction, a time when Mars moved behind the Sun from Earth’s perspective.
