- https://www.nasa.gov/mission_pages/mer/images/spirit-sol-1120.html On sol 1120 (February 26, 2007), the navigation camera aboard NASA’s Mars Exploration Rover Spirit captured one of the best dust devils it’s seen in its three-plus year mission. The series of navigation camera images were put together to make a dust devil movie. The dust devil column is clearly defined and is clearly bent in the down wind direction. Near the end of the movie, the base of the dust devil becomes much wider. The atmospheric science team thinks that this is because the dust devil encountered some sand and therefore produced a "saltation skirt,” an apron of material that is thrown out of the dust devil because it is too large to be carried up into suspension. Also near the end of the movie the dust devil seems to move faster across the surface. This is because Spirit began taking pictures less frequently, and not because the dust devil sped up.

Earth is a little left of center in the image, and our moon is just below Earth. Two annotated versions of the image are also available. Researchers used the left eye camera of Curiosity's Mast Camera (Mastcam) to capture this scene about 80 minutes after sunset on the 529th Martian day, or sol, of the rover's work on Mars (Jan. 31, 2014). The image has been processed to remove effects of cosmic rays. A human observer with normal vision, if standing on Mars, could easily see Earth and the moon as two distinct, bright "evening stars." NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the Mars Science Laboratory Project for NASA's Science Mission Directorate, Washington. JPL designed and built the project's Curiosity rover. Malin Space Science Systems, San Diego, built and operates the rover's Mastcam.
- https://mars.nasa.gov/resources/curiosity-rover-finds-and-examines-a-meteorite-on-mars/ November 2, 2016 The dark, smooth-surfaced object at the center of this Oct. 30, 2016, image from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover was examined with laser pulses and confirmed to be an iron-nickel meteorite. The grid of shiny points visible on the object resulted from that laser zapping by Curiosity's Chemistry and Camera (ChemCam) instrument. The meteorite is about the size of a golf ball. It is informally named "Egg Rock," for a site in Maine. Locations around Bar Harbor, Maine, are the naming theme for an area on Mars' Mount Sharp that Curiosity reached in October. Iron-nickel meteorites are a common class of space rocks found on Earth, and previous examples have been found on Mars, but Egg Rock is the first on Mars to be examined with a laser-firing spectrometer. The scene is presented with a color adjustment that approximates white balancing, to resemble how the rocks and sand would appear under daytime lighting conditions on Earth. Figure A includes a scale bar of 5 centimeters (about 2 inches). Malin Space Science Systems, San Diego, built and operates Mastcam. JPL, a division of Caltech, manages the Mars Science Laboratory Project for NASA's Science Mission Directorate, Washington, and built the project's Curiosity rover.
