First Hi-Res Color Mosaic of Curiosity’s Mastcam Images

This image is the first high-resolution color mosaic from NASA’s Curiosity rover, showing the geological environment around the rover’s landing site in Gale Crater on Mars. The images show a landscape that closely resembles portions of the southwestern United States in its morphology, adding to the impression gained from the lower-resolution thumbnail mosaic released early in the week.

The colors in the main image are unmodified from those returned by the camera. While it is difficult to say whether this is what a human eye would see, it is what a cell phone or camcorder would record since the Mastcam takes color pictures in the exact same manner that consumer cameras acquire color images. The colors in a second version linked to the main image have been modified as if the scene were transported to Earth and illuminated by terrestrial sunlight. This processing, called “white balancing,” is useful for scientists to be able to recognize and distinguish rocks by color in more familiar lighting.

The parts of this mosaic that are most interesting to geologists include a section on the crater wall north of the landing site where a network of valleys believed to have formed by water erosion enters Gale Crater from the outside. They are also studying a section that looks south of the landing site that provides an overview of the eventual geological targets Curiosity will explore, including the rock-strewn, gravelly surface nearby, the dark dune field and the layered buttes and mesas of the sedimentary rock of Mount Sharp.

Geologists are also taking a close look at an area excavated by the blast of the Mars Science Laboratory’s descent stage rockets. With the loose debris blasted away by the rockets, details of the underlying materials are clearly seen. Of particular note is a well-defined, topmost layer that contains fragments of rock embedded in a matix of finer material.

This 79-image mosaic was acquired by the 34-millimeter Mastcam over about an hour of time on Aug. 8, 2012 PDT (Aug. 9, 2012 EDT). The full mosaic consists of 130 1,200 by 1,200 pixel full-color images, but this version includes all the images that have been returned to Earth so far. The black areas indicate images not yet returned by the rover.

This is the first 360-degree panoramic view from NASA’s Curiosity rover, taken with the Navigation cameras. 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 near the center are full-resolution.

Mount Sharp is to the right, and the north Gale Crater rim can be seen at center. The rover’s body is in the foreground, with the shadow of its head, or mast, poking up to the right.

These images were acquired at 3:30pm on Mars, or the night of Aug. 7 PDT (early morning Aug. 8 EDT). Thumbnails are 64 by 64 pixels in size; and full-resolution images are 1024 by 1024 pixels.
