  • The Viking Files
    Three expeditions to the surface of Mars have succeeded so far: the two Viking probes in the 1970s and Mars Pathfinder in 1997. As that total is expected to double with planned launches next month (2 NASA/1 ESA probe), scientists have periodically revisited what it

  • Dune
    Satellite photos of a bright dune in the Martian southern hemisphere show remarkable details of an unusual erosion pattern. Unlike rocky avalanches found elsewhere, the dune flows suggest to two German scientists that for a few summer noon hours, liquid water may carve up the

  • Countdown: Martian Traffic Jam
    Three missions are headed to Mars over the next five weeks. All of them will hunt for evidence of water, after potentially bouncing on airbags.

  • Valley Networks: Connecting the Dots
    New data suggest that Mars's valley networks are far more extensive than previously thought. That, according to one researcher, adds weight to the idea that Mars was once much warmer and wetter than it is today. But not everyone is convinced.

  • A Perfect World III: Goldin
    "Name two things you hope will be true about the world in fifty years. Tell me about an environment in which you personally thrive. Now paint a picture of your ideal world."

  • Beagle Points to Mars
    The future Mars landing site for the European Beagle 2 mission, lies on the floor of a large impact basin in the northern hemisphere. Its low-lying plains include strings of cratered domes from ancient volcanoes and a series of small channels that indicate ancient water

  • Martian Sites Selected to Land
    The two landing sites selected for roving the Red Planet are official: one near a crater that may be a dry lakebed, and another rich in a water-formed mineral called hematite. Both continue the theme of 'following the water' in search of potential clues to

  • Hitchhikers May Have Thumbed A Ride to Mars
    Could dormant forms of bacteria called endospores potentially travel from Earth to Mars aboard spacecraft? If so, new experiments suggest that even a dry and cold Mars might not prove so inhospitable, despite the possibility of self-sterilizing and oxidizing martian soil.

  • Martian Map Quest
    The winds of time have carved a remarkable set of features onto the face of Mars. A large gallery of images from the Global Surveyor spacecraft reveal hints of what future Mars landers will navigate.

  • Roadtest for Robots
    A series of robot experiments are planned to prepare for exploring Mars. The robots will begin their roadtests by travelling unsupervised more than a 100 miles across the driest place on Earth.

  • Martian Ground Truth Sought on Dark Dunes
    A European panel of Mars experts recently debated the mystery of seasonal spots that pockmark the dark dunes on the Red Planet.

  • Lakeside Landing
    Gusev Crater, one of the landing sites proposed for the upcoming missions to Mars, is believed to the site of an ancient lakebed. By landing there, NASA hopes to learn more about Mars's watery past.

  • Red Rovers: Returning to Mars
    NASA will launch two rovers to Mars in the late spring of this year. In this, the first of two articles on potential landing sites, we will examine one of the leading candidates, Meridiani Planum.

  • Martian Liquid Center
    By watching the tidal pull on their orbitting Global Surveyor spacecraft, scientists have confirmed that Mars has a liquid iron core, much like Earth and Venus. Many astrobiologists conclude that such a molten and magnetic interior is critical to developing life.
