NASA Mars Rover Curiosity's Self-Portrait by Navcams

This Picasso-like self-portrait of NASA's Curiosity rover was taken by its navigation cameras, located on the now-upright mast. 

The camera snapped pictures 360-degrees around the rover, while pointing down at the rover deck, up and straight ahead.

Those images are shown here in a polar projection. 

Most of the tiles are thumbnails, or small copies of the full-resolution images that have not been sent back to Earth yet. Two of the tiles are full-resolution.

NASA Mars: Rover Curiosity's Heat Shield in View

This colour thumbnail image was obtained by NASA's Curiosity rover during its descent to the surface of Mars on Aug. 5 PDT (Aug. 6 EDT).

The image was obtained by the Mars Descent Imager instrument known as MARDI and shows the 15-foot (4.5-meter) diameter heat shield when it was about 50 feet (16 meters) from the spacecraft.

It was obtained two and one-half minutes before touching down on the surface of Mars and about three seconds after heat shield separation.

It is among the first color images Curiosity sent back from Mars.

The resolution of all of the MARDI frames is reduced by a factor of eight in order for them to be promptly received on Earth during this early phase of the mission.

Full resolution (1,600 by 1,200 pixel) images will be returned to Earth over the next several months as Curiosity begins its scientific exploration of Mars.

The original image from MARDI has been geometrically corrected to look flat.

Curiosity landed inside of a crater known as Gale Crater.

Guide to NASA Mars Curiosity Rover's Cameras - MARDI

Curiosity is packed with no fewer than 17 cameras to shoot high-quality photos and videos in black-and-white, color, and 3-D stereo of the Martian landscape.

While scientists are no doubt quite eager for the information that these images will contain, most of us will be excited to live vicariously through the rover and experience some breathtaking views on Mars.

First up is the Mars Descent Imager (MARDI), which recently beamed back an amazing video of the rover’s nail-biting descent.

MARDI turned on during the final few minutes of the “Seven Minutes of Terror” and recorded a full-color high-definition movie as the ground rushed up to meet the rover.

With this film (and the coming high-def version), you get to experience what the wild ride down to the surface looked like.

MARDI is a 2-megapixel wide-angle camera mounted toward the front on the port side of Curiosity. The camera came to life just after the spacecraft’s heat shield jettisoned, taking images of a roughly 2 by 2.5-mile square, with a resolution of about 8 feet per pixel.

The final fully-in-focus images came when the rover was about 15 feet off the ground. In addition to a thrilling film, MARDI will provide scientists the opportunity to know exactly where Curiosity landed and learn a bit about the surrounding area.
