Curiosity eats first dirt on Mars

2012-10-19 09:01

Washington - Nasa's Mars rover Curiosity tasted Martian dirt for the first time on Thursday, testing equipment needed to assess if the planet most like Earth in the solar system has or ever had the ingredients for microbial life.

The sampling of about a baby aspirin's worth of Martian sand was slightly delayed while scientists puzzled over unusual brightly coloured flecks in the hole carved out by Curiosity's scoop.

Initially, the team believed the bright flecks were shed by the rover, similar to bits of plastic debris discovered last week.

"The science team started to classify these sort of differently, calling them 'schmutz'," Curiosity lead scientist John Grotzinger, with the California Institute of Technology, told reporters in a conference call.

"We had a lot of fun with that, labelling them and comparing, but in the end it turns out we really feel this is a different sort of particle," he said.

Safe

While not completely ruling out the chance that the flecks are rover debris, most of the team now believes they are naturally occurring, perhaps a mineral that was fractured by the rover scoop.

To be on the safe side, scientists commanded Curiosity to dump that sample and collect sand from another site for processing in the onboard laboratory. The aim is to get an ingredient list of minerals in the Martian soil.

"We got to believing there were things around us and began to look at everything through that lens," said mission manager Richard Cook, with Nasa's Jet Propulsion Laboratory in Pasadena, California.

"We definitely are more aware of what's out there now and are more careful about everything we look at," Cook said.

In August, Curiosity landed inside a 154km-wide impact crater near the Martian equator on a $2.5bn, two-year mission to determine if Mars had the chemistry to support and preserve microbial life.

The mission is Nasa's first astrobiology initiative since the 1970s-era Viking probes.

    Interesting times indeed.

    The rover landed in a martian landfill site.

    there we go again. litter everywhere. they can't even go to another planet without littering. why the rover even shedding bits of itself? next they'll lose a wheel or something important.

      note the sarcasm...

    Can you do better?

    So is Nasa the only space agency/programme that has exclusive rights to Mars now? Actually does that mean America is gnna own Mars#gasping in confusion!
