When the topic of ice on Mars comes up, the first thing that usually comes to mind are the polar ice caps which are prominent even in small […]

Curiosity Discovers Biochemically Accessible Nitrogen, Key Ingredient Needed for Martian Life

Curiosity detected biochemically accessible nitrogen here at John Klein drill site! Curiosity accomplished historic first drilling into Martian rock at John Klein outcrop on Feb 8, 2013 (Sol 182), and discovered a habitable zone, shown in this context mosaic view of the Yellowknife Bay basin taken on Jan. 26 (Sol 169). The robotic arm […]

Opportunity Arrives at Alien Gateway to Clay Minerals at Spirit of St. Louis Crater

The View from Opportunity on Mars Today Opportunity arrives at Spirit of Saint Louis crater and peers into Marathon Valley and Endeavour crater from current location on Mars as of April 3, 2015, in this photo mosaic. The crater is the gateway to Marathon Valley and exposures of water altered clay minerals. This pancam […]

Watch Curiosity’s Scars on Mars Change Over Time

This sequence of images shows a blast zone where the sky crane from NASA’s Curiosity rover mission hit the ground after setting the rover down in August 2012, and how that dark scar’s appearance changed over the subsequent 30 months. The images are from HiRISE on NASA’s Mars Reconnaissance Orbiter. Credit: NASA/JPL-Caltech/Univ. of Arizona

Whoa! Opportunity Discovers Matchless Purplish Rocks at Spectacular Mars Overlook

NASA’s Opportunity Rover scans along a spectacular overlook towards Marathon Valley on March 3, 2015, showing flat-faced rocks exhibiting a completely new composition from others examined earlier. Marathon Valley and Martian cliffs on Endeavour crater hold deposits of water altered clay minerals. This navcam camera photo mosaic was assembled from images taken on Sol […]

Short Circuit Sidelines Curiosity’s Movements After Drilling at Telegraph Peak

This March 6, 2015 (Sol 917), mosaic of images from the Navcam camera on NASA’s Curiosity Mars rover shows the position in which the rover held its arm for several days after a transient short circuit triggered onboard fault-protection programming to halt arm activities on Feb. 27, 2015, Sol 911. The rover team chose […]

Curiosity Snaps Expansive Selfie, Sets Next Drill Campaign

This self-portrait of NASA’s Curiosity Mars rover shows the vehicle at the “Mojave” site, where its drill collected the mission’s second taste of Mount Sharp. The scene combines dozens of images taken during January 2015 by the MAHLI camera at the end of the rover’s robotic arm. Image Credit: NASA/JPL-Caltech/MSSS See drill site photomosaics […]

MAVEN Plunges to Ascertain Ancient Atmospheric Depletion at Mars

NASA’s MAVEN spacecraft is depicted in orbit around an artistic rendition of planet Mars, which is shown in transition from its ancient, water-covered past to the cold, dry, dusty world that it has become today.
