Curiosity now has driven six days in a row.
Daily distances range from 72 feet to 121 feet (22 meters to 37 meters).
"This robot was built to rove, and the team is really getting a good rhythm of driving day after day when that's the priority," said Mars Science Laboratory Project Manager Richard Cook of NASA's Jet Propulsion Laboratory in Pasadena, Calif.
The team plans to choose a rock in the Glenelg area for the rover's first use of its capability to analyze powder drilled from interiors of rocks.
Three types of terrain intersect in the Glenelg area—one lighter-toned and another more cratered than the terrain Curiosity currently is crossing.
The light-toned area is of special interest because it retains daytime heat long into the night, suggesting an unusual composition.
"As we're getting closer to the light-toned area, we see thin, dark bands of unknown origin," said Mars Science Laboratory Project Scientist John Grotzinger of the California Institute of Technology, Pasadena.
"The smaller-scale diversity is becoming more evident as we get closer, providing more potential targets for investigation."
Researchers are using Curiosity's Mast Camera (Mastcam) to find potential targets on the ground. Recent new images from the rover's camera reveal dark streaks on rocks in the Glenelg area that have increased researchers' interest in the area.
In addition to taking ground images, the camera also has been busy looking upward.
