Scientists call Mars landscape ‘Earth-like’

- ALICIA CHANG

PASADENA, Calif. — The ancient Martian crater where the Curiosity rover landed looks strikingly similar to the Mojave Desert in California with its looming mountains and hanging haze, scientists said Wednesday.

“The first impression that you get is how Earth-like this seems looking at that landscape,” said chief scientist John Grotzinger of the California Institute of Technology.

Overnight, the car- size rover poked its head out for the first time since settling in Gale Crater, peered around and returned a flood of blackand-white pictures that will be stitched into a panorama.

It provided the best view so far of its destinatio­n since touching down Sunday night after nailing an intricate choreograp­hy. During the last few seconds, a rocket-powered spacecraft hovered as cables lowered Curiosity.

In the latest photos, Curiosity looked out toward the northern horizon. Nearby were scour marks in the surface blasted by thrusters, which kicked up a swirl of dust. There were concerns that Curiosity got dusty, but scientists said that was not the case.

“We do see a thin coating of dust, but nothing too bad,” said Justin Maki, imaging scientist at NASA’S Jet Propulsion Laboratory, which manages the $2.5 billion mission.

Scientists were giddy about the trenches because it meant Curiosity could drive up to them and start collecting samples once the science phase of the mission gets under way.

Since landing, Curiosity has zipped home a stream of lowresolut­ion pictures taken by tiny cameras under the chassis and a camera at the end of its robotic arm, which remained stowed. It also sent back a lowquality video glimpsing the last 2 1⁄2 minutes of its descent.

The rover successful­ly raised its mast packed with high-resolution and navigation cameras. With the mast up, it can begin its shutterbug days in force including taking a 360-degree color view of its surroundin­gs as early as today.

Grotzinger said he was struck by the Martian landscape, which appeared diverse. There seemed to be harder bedrock underneath the gravelly surface, he said.

“It kind of makes you feel at home,” he said. “We’re looking at a place that feels really comfortabl­e.”

Mars, of course, is a frigid desert constantly bombarded by radiation. There are geological signs that it once was a warmer and wetter place.

After sailing 352 million miles and eight months, Curiosity parked its six wheels near the Martian equator where it will spend the next two years poking into rocks and soil in search of the chemical ingredient­s of life.
