On Dec. 14, 1962, NASA’s Mariner 2 spacecraft sailed close to Venus, marking the first time any spacecraft had ever successfully made a close-up study of another planet. Image credit: NASA/JPL-Caltech Fifty years ago on a mid-December day, NASA’s Mariner 2 sp... More »
This image from NASA’s Cassini spacecraft shows a vast river system on Saturn’s moon Titan. It is the first time images from space have revealed a river system so vast and in such high resolution anywhere other than Earth. Image Credit: NASA/JPL-Caltech/ASI ... More »
On the 84th and 85th Martian days of the NASA Mars rover Curiosity’s mission on Mars (Oct. 31 and Nov. 1, 2012), NASA’s Curiosity rover used the Mars Hand Lens Imager (MAHLI) to capture dozens of high-resolution images to be combined into self-portrait images ... More »
Layered Martian Outcrop ‘Shaler’ in ‘Glenelg’ Area The NASA Mars rover Curiosity used its Mast Camera (Mastcam) during the mission’s 120th Martian day, or sol (Dec. 7, 2012), to record this view of a rock outcrop informally named “Shaler.” Image credit: NASA/J... More »
