Team members of NASA's Mars Science Laboratory mission took a test rover to Dumont Dunes in California's Mojave Desert this week to improve knowledge of the best way to operate a similar rover, Curiosity, currently flying to Mars for an August landing.
The test rover that they put through paces on various sandy slopes has a full-scale version of Curiosity's mobility system, but it is otherwise stripped down so that it weighs about the same on Earth as Curiosity will weigh in the lesser gravity of Mars.
Information collected in these tests on windward and downwind portions of dunes will be used by the rover team in making decisions about driving Curiosity on dunes near a mountain in the center of Gale Crater.
First, however, the Mars Science Laboratory spacecraft, launched Nov. 26, 2011, must put Curiosity safely onto the ground. Safe landing on Mars is never assured, and this mission will use innovative methods to land the heaviest vehicle in the smallest target area ever attempted on Mars.
Advances in landing heavier payloads more precisely are steps toward eventual human missions to Mars.
Curiosity is on track for landing the evening of Aug. 5, 2012, PDT (early on Aug. 6, Universal Time and EDT) to begin a two-year prime mission. Researchers plan to use Curiosity to study layers in Gale Crater's central mound, Mount Sharp.
The mission will investigate whether the area has ever offered an environment favorable for microbial life.

100 Days and Counting to NASA's Curiosity Mars Rover Landing
Pasadena CA (JPL) Apr 30, 2012
At 10:31 p.m. PDT April 27, (1:31 p.m. EDT), NASA's Mars Science Laboratory, carrying the one-ton Curiosity rover, will be within 100 days from its appointment with the Martian surface. At that moment, the mission has about 119 million miles (191 million kilometers) to go and is closing at a speed of 13,000 mph (21,000 kilometers per hour).
