[…]

  • Mars new home 'a large sandbox'
    on November 30, 2018 at 4:11 pm

    With InSight safely on the surface of Mars, the mission team at NASA's Jet Propulsion Laboratory in Pasadena, California, is busy learning more about the spacecraft's landing site. They knew when InSight landed on Nov. 26 that the spacecraft had touched down on target, a lava plain named Elysium Planitia. Now they've determined that the vehicle sits slightly tilted (about 4 degrees) in a shallow dust- and sand-filled impact crater known as a "hollow." InSight has been engineered to operate on a surface with an inclination up to 15 degrees. […]

  • NASA Hears MarCO CubeSats Loud and Clear from Mars
    on November 27, 2018 at 7:31 pm

    NASA's MarCO mission was built to see whether two experimental, briefcase-sized spacecraft could survive the trip to deep space, and the two CubeSats proved more than able. After cruising along behind NASA's InSight for seven months, they successfully relayed data back down to Earth from the lander during its descent to the Martian surface on Monday, Nov. 26. […]

  • Overflowing crater lakes carved canyons across Mars
    on November 16, 2018 at 9:45 pm

    Today, most of the water on Mars is locked away in frozen ice caps. But billions of years ago it flowed freely across the surface, forming rushing rivers that emptied into craters, forming lakes and seas. New research has found evidence that sometimes the lakes would take on so much water that they overflowed and burst from the sides of their basins, creating catastrophic floods that carved canyons very rapidly, perhaps in a matter of weeks. […]

  • Scientists capture the 'sound' of sunrise on Mars
    on November 9, 2018 at 3:14 pm

  • Naturally occurring 'batteries' fueled organic carbon synthesis on Mars
    on October 31, 2018 at 6:15 pm

    Mars' organic carbon may have originated from a series of electrochemical reactions between briny liquids and volcanic minerals, according to analyses of three Martian meteorites. The discovery that natural systems can form a small corrosion-powered battery that drives electrochemical reactions between minerals and surrounding liquid has major implications for astrobiology. A similar process could occur anywhere that igneous rocks are surrounded by brines, including the subsurface oceans of Jupiter's moon Europa and Saturn's moon Enceladus. […]

  • Mars: Oxygen-rich, life-supporting liquid water?
    on October 22, 2018 at 9:19 pm

    Given the right circumstances, water on Mars could hold more oxygen than previously believed, theoretically enough to support aerobic respiration, new research suggests. […]

  • NASA's first image of Mars from a CubeSat
    on October 22, 2018 at 9:13 pm

  • Martian moon may have come from impact on home planet
    on September 24, 2018 at 6:40 pm

    Phobos, the larger of Mars' two tiny satellites, is the darkest moon in the solar system. This dark aspect inspired the hypothesis that the close-orbiting moon may be a captured asteroid, but its orbital dynamics seemed to disagree. A new study suggests Phobos' composition may be more like the volcanic crust of the Red Planet than it appears, consistent with an origin for the moon in an ancient, violent impact on Mars. […]

  • Ancient Mars had right conditions for underground life, new research suggests
    on September 24, 2018 at 2:20 pm

  • Mars terraforming not possible using present-day technology
    on July 30, 2018 at 4:03 pm

    Science fiction writers have long featured terraforming, the process of creating an Earth-like or habitable environment on another planet, in their stories. Scientists themselves have proposed terraforming to enable the long-term colonization of Mars. A solution common to both groups is to release carbon dioxide gas trapped in the Martian surface to thicken the atmosphere and act as a blanket to warm the planet. […]

  • New family photos of Mars and Saturn from Hubble
    on July 26, 2018 at 8:10 pm

    In summer 2018 the planets Mars and Saturn are, one after the other, in opposition to Earth. During this event the planets are relatively close to Earth, allowing astronomers to observe them in greater detail. Hubble took advantage of this preferred configuration and imaged both planets to continue its long-standing observation of the outer planets in the solar system. […]
