Next Mars rover nears completion

( -- Assembly and testing of NASA's Mars Science Laboratory spacecraft is far enough along that the mission's rover, Curiosity, looks very much as it will when it is investigating Mars.

Testing continues this month at NASA's Jet Propulsion Laboratory, Pasadena, Calif., on the rover and other components of the spacecraft that will deliver Curiosity to Mars. In May and June, the will be shipped to Kennedy Space Center, Fla., where preparations will continue for launch in the period between Nov. 25 and Dec. 18, 2011.

The mission will use to study one of the most intriguing places on Mars -- still to be selected from among four finalist landing-site candidates. It will study whether a selected area of Mars has offered environmental conditions favorable for microbial life and for preserving evidence about whether Martian life has existed.

What's more, most of the technology on it is already obsolete.

They even scrapped the 3-d camera that was supposed to be installed on it.

I think, it will be a camera on Curiosity, maybe not 3D( like Cameroon wanted), but it will be recording some interesting HD movies for us, if they banned whode camera idea, that sucks !

Obsolete in what sense? Radiation-hardened and space-hardened hardware (and in the case of the rover, it's both of the above) always lags behind off-the-shelf hardware by two or three generations. As far as space-faring designs go, I don't think there's any basis for denigrating the rover's technology as "already obsolete".

Why not send humans? We have the technology and the plan (Mars Direct)
Manned space exploration is necessary for humankind's future, as Earth will not always be the comparative paradise it is today.

why can't they send something that can fly around the planet...these rovers are too slow..........we need something like that in return of the jedi

Why not send humans?
Because with modern technology it's still unnecessarily dangerous, and completely unaffordable.
why can't they send something that can fly around the planet...
It's rather difficult to fly in such a thin atmosphere (the pressure at Mars' SURFACE -- never mind high above the surface -- is about the same as air pressure on Earth at an altitude of 36 km, or 118,000 feet.) One would need a very large wingspan, and very small payload. And even then, it takes a lot more energy to fly than it does to slowly roll along the ground.

Plus, flyers can't sample soil, drill into rocks, and pick things up and put them under a microscope...
