No matter how far you go, it’s always nice to keep in touch with the folks back home. That’s especially true for a spacecraft that has traveled millions of miles just to send pictures and other information from the surface of Mars back to scientists on Earth.
On June 19, researchers at NASA released their biggest, most detailed picture ever of the surface of Mars. For space fans following the progress of NASA’s Mars rover — named “Curiosity” — as it explores the surface of the Red Planet, pictures are nothing new. One of the great things about NASA is that mission scientists share lots of the data sent back to Earth. Armchair explorers can browse information on the Web — photos, charts, maps, animations and multimedia — alongside scientists around the world.
But the latest picture is NASA’s hugest ever (in camera terms, more than one billion pixels!), which means you can change your viewing angle, move it around and look at different parts of it. When you see something interesting, you can zoom in for closer inspection. See an interesting rock a mile away? No problem. Click and zoom until you get a better look.
It’s as close as you can get to taking a stroll around the surface of Mars.
The reason such detail is possible is that the image is made by stitching together nearly 900 pictures taken by Curiosity as it moved around the surface. The pictures were taken over several days in the October and November of 2012. The area photographed includes a windblown patch named “Rocknest,” and extends to Mount Sharp on the horizon. “It gives a sense of place and really shows off the cameras’ capabilities,” said Bob Deen of the Multi-Mission Image Processing Laboratory at NASA’s Jet Propulsion Laboratory, Pasadena, Calif.

The updated area, which is in the lower left quadrant of the image, shows gray-powder and two holes where Curiosity used its drill on the rock target “John Klein.” The portion has been spliced into a self-portrait that was prepared and released in February (http://photojournal.jpl.nasa.gov/catalog/PIA16764), before the use of the drill. The result shows what the site where the self-portrait was taken looked like by the time the rover was ready to drive away from that site in May 2013.
The rover’s robotic arm is not visible in the mosaic. MAHLI, which took the component images for this mosaic, is mounted on a turret at the end of the arm. Wrist motions and turret rotations on the arm allowed MAHLI to acquire the mosaic’s component images. The arm was positioned out of the shot in the images, or portions of images, used in the mosaic.
Malin Space Science Systems, San Diego, developed, built and operates MAHLI. NASA’s Jet Propulsion Laboratory, Pasadena, Calif., manages the Mars Science Laboratory Project and the mission’s Curiosity rover for NASA’s Science Mission Directorate in Washington. The rover was designed and assembled at JPL, a division of the California Institute of Technology in Pasadena.
