The Mars Exploration Rover Opportunity is still exploring Mars. Below is a brief field report summary of its latest activity.

Opportunity is continuing its drive down Persevereance Valley, a channel that was cut in the inner wall of the 22 km-diameter Endeavour impact crater in ancient Mars (Noachian) time. This is the second stop of a series of stops as Opportunity drives down the valley. The goal is to collect field data that will help assess the origin of the valley. While the valley looks like a water-cut valley, we cannot be sure whether other processes like wind or drive flow have cut the valley. But that is why we are taking our time and collecting data as we drive.

On sol3451 Opportunity began its climb of Solander Point. This is the highest “mountain” that Opportunity has tried to climb yet. The nice thing about this climb is the fact that it is all on a slope that faces north. Opportunity is solar powered, so north tilts are better for power generation during the winter here just south of the equator.

• Opportunity "wades ashore" at Solander Point on September 13

• climbing Solander Point is imminent

• spectacular Navcam panorama of the major geologic contact at this location


• Opportunity is at the base of Solander Point

• a boulder field here appears to be mostly vesicular basalt, a rock type that is not local

• shortly Opportunity will drive northwest along the scarp at the base of Solander Point


Opportunity arrived at the base of the next segment of the Endeavour crater rim and is now investigating the contact.

• less than 100m to go before “land fall” on Solander Point

• the next drive will put Opportunity at the “shore”

• a “new world” is about to be explored; what strange rocks and structures will we encounter?


• About to finish last observations in the plains before arrival at the next mountain

• There is a short stop here to measure one last rock in the plains

• Launch occurred over 10 years ago!


• Opportunity is only a couple of hundred meters out and closing fast on the next mountain

• A short side trip east is in the works to check out an anomaly in the terrain


• Opportunity just turned 5 Mars years old (a few months short of 10 Earth years)
• Opportunity just exceeded 37 kilometers of odometry
• On Sol 3325 Opportunity has driven up onto the next “island” of rock,  “Sutherland Point” and “Nobbys Head.”
• On this sol Opportunity is only about 700 m from the goal, the mountains to the south.
