$Water on Mars Visual Data Exposed by Mars Reconnaissance Orbiter http://www.SpaceChronology.com Courtesy NASA/JPL-Caltech 1 Oblique View of Warm Season Flows in Newton Crater An image combining orbital imagery with 3-D modeling shows flows that appear in spring and summer on a slope inside Mars Newton crater. Image credit: NASA/JPL-Caltech/Univ. of Arizona 2. Ice, Salt and Warm-Season Flows on Mars This map of Mars shows relative locations of three types of findings related to salt or frozen water, plus a new type of finding that may be related to both salt and water. Image Credit: NASA/JPL-Caltech/ASU/UA/LANL/MSSS 3. Plausible Martian Habitats Unfrozen brine in cryopegs and fracture networks provides habitats for the survival and growth of organisms both within and under frozen rocky materials on Earth and, by analogy, could provide habitats on Mars.

Warm-Season Flows on Slope in Newton Crater This series of images shows warm-season features that might be evidence of salty liquid water active on Mars today. Image credit: NASA/JPL-Caltech/Univ. of Arizona 5. Warm-Season Flows on Slope in Newton Crater (Five-Image Sequence) This series of images shows warm-season features that might be evidence of salty liquid water active on Mars today. Image credit: NASA/JPL-Caltech/Univ. of Arizona 6. Dark Flows in Newton Crater Extending During Summer (Six-Image Sequence) This series of images shows warm-season features that might be evidence of salty liquid water active on Mars today. Image credit: NASA/JPL-Caltech/Univ. of Arizona 7. Warm-Season Flows on Slope in Horowitz Crater (Eight-Image Sequence) Evidence for that possible interpretation is presented in a report by McEwen et al. in the Aug. 5, 2011, edition of Science. Image credit: NASA/JPL-Caltech/Univ. of Arizona 8. Warm-Season Flows on Slope in Horowitz Crater (Nine-Image Sequence) This series of images shows warm-season features that might be evidence of salty liquid water active on Mars today. Image credit: NASA/JPL-Caltech/Univ. of Arizona 9. Warm-Season Flows on Steep Slope in Slope in Terra Cimmeria (Eight-Image Sequence) This series of images shows warm-season features that might be evidence of salty liquid water active on Mars today. Image credit: NASA/JPL-Caltech/Univ. of Arizona 10. Warm-Season Flows in Well-Preserved Crater in Terra Sirenum (Six-Image Sequence) This series of images shows warm-season features that might be evidence of salty liquid water active on Mars today. Image credit: NASA/JPL-Caltech/Univ. of Arizona 11. Gullies and Newly Identified Flow Features in Same Mars Crater This image contrasts gullies and recurring warm-season slope flows appearing in the same crater, in the middle southern latitudes of Mars. Image credit: NASA/JPL-Caltech/University of Arizona 12. Changes in a Gully in a Mars Crater (Two-Image Comparison) This back and forth comparison shows changes that occurred in a gully on a south-facing slope in middle southern latitudes of Mars.
