This close-up image of a penny shows the degree to which the microscopic imager on NASA Mars Exploration Rover Spirit can zoom in on a target.

Penny for Your Reference

The penny in this image is part of a camera calibration target on NASA Mars rover Curiosity. The MAHLI camera on the rover took this image of the MAHLI calibration target during the 34th Martian day of Curiosity work on Mars, Sept. 9, 2012.

This image of a U.S. penny on a calibration target was taken by the Mars Hand Lens Imager MAHLI aboard NASA Curiosity rover in Gale Crater on Mars. At 14 micrometers per pixel, this is the highest-resolution image that MAHLI can acquire.

Two instruments at the end of the robotic arm on NASA Mars rover Curiosity will use calibration targets attached to a shoulder joint of the arm. The penny is a size reference giving the public a familiar object for perceiving size on Mars easily.

Curiosity Finds a Martian Flower

Smaller than a penny, the flower-like rock artifact on the left was imaged by NASA's Curiosity Mars rover using its Mars Hand Lens Imager (MAHLI) camera on the end of its robotic arm. The image was taken on Feb. 24, 2022, the 3,396th Martian day, or sol, of the mission. The "flower," along with the spherical rock artifacts seen to the right, were made in the ancient past when minerals carried by water cemented the rock. Figure 1 shows a tighter view of the flower-like feature. Curiosity has in the past discovered a diverse assortment of similar small features that formed when mineralizing fluids traveled through conduits in the rock. Images of such features are helping scientists understand more about the prolonged history of liquid water in Gale Crater. https://photojournal.jpl.nasa.gov/catalog/PIA25077

The suit allows him to be outside during the day, which would otherwise be impossible. Jonathan's trip was funded by the Make-A-Wish Foundation and included a visit to Disney World. He and his family were among a dozen VIPs at KSC to view the launch of STS-99

Tumbiana Stromatolite

This image shows the finely layered internal structure of a stromatolite sample, with a U.S. penny for scale. This stromatolite formed about 2.7 billion years ago and was collected from an ancient lake environment preserved in the Tumbiana Formation, a succession of clastic and carbonate rocks outcropping along the southern margin of the Pilbara Craton in Western Australia. The view here is top down on what was once a dome that has been eroded flat, revealing the internal layering. Stromatolites form when communities of microorganisms organize into layered "microbial mats" that can trap and bind sediment or stimulate the precipitation of mineral grains from the water around them, both processes generating a kind of "living fossil." However, living stromatolites can rarely be found on Earth today. Stromatolite fossils are the dominant record of life for most of Earth's history prior to the appearance of complex, multicellular organisms. Scientists are seeking something similar to stromatolites in the dry lakebed Perseverance will be exploring on Mars. https://photojournal.jpl.nasa.gov/catalog/PIA24240
