Curiosity scientists have tracked Gale Crater’s changing environment as it became more, then less, acidic over millions of years. Microbial life could have survived in these conditions. The post Curiosity Tracks Mars’s Ancient Habitability with Rocks appeared first on Sky & Telescope.
This view obtained on July 9 from the left Navigation Camera (Navcam) of NASA's Mars Rover Curiosity looks back at wheel tracks made during the first drive away from the last science target in the "Glenelg" area.
This image is of Sojourner and the very first set of tracks on Mars. A far cry from the complex sky crane landing of the Mini Cooper-sized Curiosity, NASA’s pioneering planetary rover was encased in a set of air bags and bounced to a stop on the Martian surface like an errant volley ball at the beach. The diminutive Sojourner was only two feet long, a foot tall, and 23 pounds. Or you know, about the size of an obese cat.
The High Resolution Imaging Science Experiment (HiRISE) on board the Mars Reconnaissance Orbiter snapped a color, high-resolution image of Curiosity's landing site in an image released January 30, 2013. The two white spots on the right side of the photograph are where the sky crane's rockets blew away surface materials as it delivered the red planet's latest rover. HiRISE also picked up Curiosity's track marks (darker double lines) leading away from the landing site.
Former foreign correspondent Wren begins retirement by embarking on a 400 mile solo hike. Traveling with a keen curiosity, Wren leaves from Manhattan and saunters northward. As his trek takes him into new states and over mountains, the challenges become as much emotional as physical. He loses track of time, wakes with the sun, and camps under starry skies. Wren has woven a story that is candid and often downright hilarious.
On Aug. 28, 2012, during the 22nd Martian day, or sol, after landing on Mars, NASA's Curiosity rover drove about 52 feet (16 meters) eastward, the longest drive of the mission so far. Image credit: NASA/JPL-Caltech
