Photos of the Day: A Martian Diva

By NASA | September 14, 2012

As Curiosity finishes the testing of its equipment on the red planet, the rover has started taking several self-portraits. Pictured here, the left eye of the Mast Camera (Mastcam) on NASA’s Mars rover Curiosity took this image of the camera on the rover’s arm, the Mars Hand Lens Imager (MAHLI), during the 30th Martian day, or sol, of the rover’s mission on Mars (Sept. 5, 2012). MAHLI is one of the tools on a turret at the end of the rover’s robotic arm. When this image was taken, the arm had raised the turret to about the same height as the camera on the mast. The Mastcam’s left eye has a 34-millimeter focal length lens. The image shows that MAHLI has a thin film or coating of Martian dust on it. This dust accumulated during Curiosity’s final descent to the Martian surface, as the Mars Science Laboratory spacecraft’s descent stage (or sky crane) engines were disrupting the surface nearby. Effects of the dust were seen in the first image taken of Mars by MAHLI, on the day after landing (http://photojournal.jpl.nasa.gov/catalog/PIA15691). The MAHLI lens is protected from dust accumulation by a transparent dust cover. If the dust cover were clean, the images would appear as clear as if the cover were open.

This image shows the Alpha Particle X-Ray Spectrometer (APXS) on NASA’s Curiosity rover, with the Martian landscape in the background. The image was taken by Curiosity’s Mast Camera on the 32nd Martian day, or sol, of operations on the surface (Sept. 7, 2012, PDT or Sept. 8, 2012, UTC). APXS can be seen in the middle of the picture.

This image let researchers know that the APXS instrument had not become caked with dust during Curiosity’s dusty landing.

Scientists enhanced the color in this version to show the Martian scene as it would appear under the lighting conditions we have on Earth, which helps in analyzing the terrain.

The image was taken by Curiosity’s Mast Camera on the 32nd Martian day, or sol, of operations on the surface (Sept. 7, 2012, PDT or Sept. 8, 2012, UTC). MAHLI, with its LED (light-emitting diode) lights on, can be seen in the middle of the picture. Scientists and engineers imaged MAHLI to inspect its dust cover and check that its LED lights are functional.

This image from NASA’s Curiosity rover shows the open inlet where powered rock and soil samples will be funneled down for analysis. It was taken by the Mars Hand Lens Imager (MAHLI) on Curiosity’s 36th Martian day, or sol, of operations on Mars (Sept. 11, 2012). MAHLI was about 8 inches (20 centimeters) away from the mouth of the Chemistry and Mineralogy (CheMin) instrument when it took the picture. The entrance of the funnel is about 1.4 inches (3.5 centimeters) in diameter. The mesh screen is about 2.3 inches (5.9 centimeters) deep. The mesh size is 0.04 inches (1 millimeter). Once the samples have gone down the funnel, CheMin will be shooting X-rays at the samples to identify and quantify the minerals.

Engineers and scientists use images like these to check out Curiosity’s instruments. This image is a composite of eight MAHLI pictures acquired at different focus positions and merged onboard the instrument before transmission to Earth; this is the first time the MAHLI performed this technique since arriving at Curiosity’s field site inside Gale Crater. The image also shows angular and rounded pebbles and sand that were deposited on the rover deck during landing on Aug. 5, 2012 PDT (Aug. 6, 2012 EDT).
