The Mars landing sky show

The announcement by NASA of the voice transmission, the latest in a series of advances by Curiosity since it landed on Mars earlier this month, comes just days after the death of Neil Armstrong, the first man to walk on the moon.

“We hope these words will be an inspiration to someone alive today who will become the first to stand upon the surface of Mars,” Dave Lavery, NASA Curiosity program executive, said in the agency’s statement. “And like the great Neil Armstrong, they will speak aloud of that next giant leap in human exploration.”


As well as the voice recording, NASA on Monday released new photos of the Martian landscape taken by Curiosity. The images show the knobbly terrain on the side of Mount Sharp, an area that Curiosity is eventually intended to explore.

Mount Sharp was formed from hundreds of rock layers that built up over time. The mountain is about 3 miles high, but the rover will trek up a small portion of it, testing different layers for signs that life could have once existed on Mars. It may take about a year for the rover to reach this target.

Curiosity already is sending back more data from the surface of Mars than the combined results of all of NASA’s previous rovers, the space agency said Monday.

Last week, it completed its first drive on Mars, setting the stage for it to venture farther afield.

Despite the complexity of landing a 2,000-pound vehicle on another planet, Curiosity had a perfect landing on August 6, and most of the instruments scientists have tested appear to function.

There’s only been one glitch so far: a wind sensor on the rover’s weather station was damaged and the reason might always remain mysterious, scientists say.
