NASA's Perseverance Rover 22 Days From Mars Landing Perseverance’s Stages of Descent (Illustration): This illustration depicts the some of the major milestones NASA’s Perseverance rover will go through during its seven-minute descent to the Martian surface on Feb. 18, 2021. Credit: NASA/JPL-Caltech. Full image and caption › Seven minutes of harrowing descent to the Red Planet is in the not-so-distant future for the agency’s Mars 2020 mission. NASA’s Mars 2020 Perseverance rover mission is just 22 days from landing on the surface of Mars. The spacecraft has about 25.6 million miles...

January 26, 2021 Earth has had at least 5 major ice ages. Now it appears Mars – the next planet outward from the sun – has undergone anywhere from half a dozen to 20 ice ages in the past several hundred million years. Glaciers below three craters in the Hellas Planitia region of Mars, now covered by rocky debris (left) and what they might look like if the ice was exposed (right). The image was created using image data from the Context Camera (CTX) on the Mars Reconnaissance Orbiter (MRO) spacecraft combined with results from the Shallow Radar (SHARAD) on MRO and High Resolution Stereo Ca...

Copy link for An AI Has Discovered New Craters on Mars If you've ever played one of those "spot the difference between these two photos" games, you have something in common with NASA scientists. To identify newly formed craters on Mars, they'll spend about 40 minutes analyzing a single photo of the Martian surface taken by the Context Camera on NASA's Mars Reconnaissance Orbiter (MRO), looking for a dark patch that wasn't in earlier photos of the same location. If a scientist spots the signs of a crater in one of those images, it then has to be confirmed using a higher-resolution photogra...

Using data from the Context Camera aboard NASA’s Mars Reconnaissance Orbiter, planetary researchers have generated an 8-trillion-pixel global map of Mars and performed the first systematic global survey of Martian fluvial (river) ridges. This image shows a suite of fluvial ridges on Mars (at –67.64 °E, 43.37 °S). Image credit: J. Dickson. Mars used to be a wet world, as evidenced by rock records of lakes, rivers, and glaciers. The Martian river ridges were formed between 4 and 3 billion years ago (the Noachian to Hesperian period), when large rivers deposited sediments in their channels...

NASA Fits Orbiter Camera With AI to Track Changes on Mars Plus, drones that can plant thousands of trees in a day, mobile Microsoft data centers designed to set up in remote or hazardous locations, and a five-story building in Shanghai that “walked” itself down the street. 6,830 Scientists are applying AI to space exploration to track changes in celestial bodies over time. Researchers at NASA’s Jet Propulsion Laboratory fed an algorithm 6,830 images taken by the Context Camera that’s part of the Mars Reconnaissance Orbiter to train it on what to look for, then gave it 112,000 images t...
