Curiosity, from Mars[SND]

Nasa Mars Yard at Nasa's Jet Propulsion Laboratory is shown with a model of Mars robot, Curiosity, during a media demonstration, in Pasadena, Calif., Wednesday, July 25, 2012. On Sunday, Aug. 5th, after 8 and a half months in transit, Curiosity will parachute onto the Martian surface to hunt for the chemical building blocks of life. (AP Photo/Nick Ut)

This photo provided by NASA shows a full-resolution version of one of the first images taken by a rear Hazard-Avoidance camera on NASA's Curiosity rover, which landed on Mars the Sunday evening, Aug. 5, 2012. The image was originally taken through a 'fisheye' wide-angle lens, but has been 'linearized' so that the horizon looks flat rather than curved. A Hazard-avoidance camera on the rear-left side of Curiosity obtained this image. Part of the rim of Gale Crater, which is a feature the size of Connecticut and Rhode Island combined, stretches from the top middle to the top right of the image. One of the rover's wheels can be seen at bottom right. (AP Photo/NASA/JPL-Caltech)

The rover's primary mission today will be raising its high-gain antenna, which will enable better communication with JPL scientists. (AP Photo/Damian Dovarganes)

NASA has released a low-resolution video of the Curiosity rover during the final few minutes of its descent to the Martian surface. An image shows the protective heat shield falling away as the rover plummeted through the Mars' atmosphere, and dust was being kicked up as it was lowered by cables inside a crater.

In this image released by NASA/JPL-Caltech/Univ. of Arizona, NASA's Curiosity rover and its parachute, left, descend to the Martian surface on Sunday, Aug. 5, 2012. The high-resolution Imaging Science Experiment (HiRISE) camera captured this image of Curiosity while the orbiter was listening to transmissions from the rover. The inset image is a cutout of the rover stretched to avoid saturation. The rover is descending toward the etched plains just north of the sand dunes that fringe 'Mt. Sharp.'

This artist's rendering released by NASA/JPL-Caltech on Sunday, Aug. 5, 2012, shows how NASA's Curiosity rover will communicate with Earth during landing. As the rover descends to the surface of Mars, it will send out two different types of data: basic radio-frequency tones that go directly to Earth (pink dots) and more complex UHF radio data (blue circles) that require relaying by orbiters. NASA's Odyssey orbiter will pick up the UHF signal and relay it immediately back to Earth, while NASA's Mars Reconnaissance Orbiter will record the UHF data and play it back to Earth at a later time.

NASA's newly landed Mars science rover Curiosity snapped the first colour image of its surroundings while an orbiting sister probe photographed litter left behind during the rover's daring do-or-die descent to the surface, scientists said Tuesday. 

Curiosity's colour image, taken with a dust cover still on the camera lens, shows the north wall and rim of Gale Crater, a vast basin where the nuclear-powered, six-wheeled rover touched down Sunday night after flying through space for more than eight months.
