NASA is aiming to launch a rocket to an asteroid in five years and grab a boulder off of it — a stepping stone for an eventual trip sending humans to Mars.

NASA's Curiosity rover results confirm that Mars has lost most of its atmosphere, on its way to becoming a cold, dry planet. In experimental results reported Monday at a European geoscience meeting in Vienna, Austria, a look at the Martian air by the $2.5 billion rover finds evidence that as much as 90% of the original atmosphere there has dissipated into space over the planet's lifetime. "It was still red, but it means that Mars once was a warmer, wetter world," says rover team scientist Sushil Atreya of the University of Michigan. "It was also a more habitable world, essentially four billion years ago."

NASA scientists say tests on a Mars rock show the planet could have supported primitive life. The analysis was done by the rover Curiosity, which drilled into the rock, crushed it and tested a tiny sample. The rover was the first spacecraft sent to Mars that could collect a sample from deep inside a rock.

The Mars rover Curiosity drilled into the Martian surface for the first time as part of an effort to learn if the planet most like Earth in the solar system ever had conditions to support microbial life, NASA said on Saturday.

Nasa scientists are planning to capture a 500 ton asteroid , relocate it and turn it into a space station for astronauts on their way to Mars. The White House's Office of Science and technology will consider the £1.6bn plan in the coming weeks as it prepares to set its space exploration agenda for the next decade.

Science editor Alan Boyle's blog: Although NASA's Curiosity rover hasn't yet confirmed the detection of organic compounds on Mars, it's already seeing that the Red Planet's soil contains complex chemicals, including perchlorate.

This nearly global mosaic of observations made by the Mars Color Imager on NASA's Mars Reconnaissance Orbiter on Nov. 18, 2012, shows a dust storm in Mars' southern hemisphere.

Curiosity is living up to its name. The NASA rover currently wheeling itself around Mars has apparently sent back some very interesting data from the Red Planet in the form of a soil sample that shows ... well, something. From the sounds of it, something big. But for now at least, that's all anyone is willing to say.

Radiation levels at the Martian surface appear to be roughly similar to those experienced by astronauts in low-Earth orbit, NASA's Mars rover Curiosity has found. The rover's initial radiation measurements — the first ever taken on the surface of another planet — may buoy the hopes of human explorers who may one day put boots on Mars, for they add more support to the notion that astronauts can indeed function on the Red Planet for limited stretches of time.

NASA's Curiosity rover reports confirmation that Mars has lost at least half of its early atmosphere.
