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.

This mosaic (upper right) shows a close-up view of the rock target named ‘Yeehgo’ from the SuperCam instrument on NASA’s Perseverance rover on Mars. The component images were taken by SuperCam’s Remote Micro-Imager (RMI) on March 7, 2021. To be compatible with the rover’s software, ‘Yeehgo’ is an alternative spelling of ‘Yéigo,’ the Navajo word for diligent. The target is 3.325 m (10.9 feet) from the rover. Each of the two images in the mosaic shows a field of view 6.2 cm (2.5 inches) in diameter. Perseverance’s Navigation Cameras (Nav Cam) and Mastcam-Z instrument also took images of that area at the same time to provide multiple views of the rock target.
