The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter captured this image of the larger of Mars’ two moons, Phobos, on March 23, 2008. The image was taken from a distance of about 6,800 km (about 4,200 miles). It is presented in color by combining data from the camera’s blue-green, red, and near-infrared channels. The illuminated part of Phobos seen in the image is about 21 km (13 miles) across. The most prominent feature is the large crater Stickney in the lower right. With a diameter of 9 km (5.6 miles), it is the largest feature on Phobos. Image credit: NASA / JPL-Caltech / University of Arizona.

Enceladus’ tiger stripes are known to be spewing ice from the moon’s icy interior into space, creating a cloud of fine ice particles over the moon’s south pole and creating Saturn’s mysterious E-ring. Evidence for this has come from NASA’s Cassini spacecraft that orbited Saturn from 2004 to 2017. Pictured here, a high resolution image of Enceladus is shown from a close flyby. Tiger stripes are visible in false-color blue. Image credit: NASA / ESA / JPL / SSI / Cassini Imaging Team.
