  • Wintering on Mars
    NASA's Mars rover Spirit has reached a safe site for the Martian winter, while its twin, Opportunity, is making fast progress toward a destination of its own. The two rovers recently set out on important -- but very different -- drives after earlier weeks inspecting

  • Mars Cold Case
    Evidence never dies in the popular TV show Cold Case. Nor do some traces of life disappear on Earth, Mars, or elsewhere. An international team of scientists has developed techniques to detect miniscule amounts of biological remains, dubbed biosignatures, in the frozen Mars-like terrain of

  • MRO Hits Its Mark
    The Mars Reconnaissance Orbiter peeked from behind the Red Planet and told mission scientists it survived the journey. Breathing a huge sigh of relief, the scientists now plan to reduce its current elongated orbit around Mars into a more circular one.

  • MRO Approaches Mars
    On Friday, the Mars Reconnaissance Orbiter (MRO) will reach Mars. Will it start orbiting the planet, fly right past it, or dive too close to the atmosphere and burn up? Because the spacecraft must loop behind the planet, mission scientists won´t know the

  • Roving the Red Planet
    NASA's Mars rovers, Spirit and Opportunity, have been working overtime to help scientists better understand ancient environmental conditions on the red planet. NASA's third mission extension for the rovers lasts through September 2006, if they remain usable that long.

  • Seeing Life in the Land
    One of the paradoxes of recent explorations of the Martian surface is that the more we see of the planet, the more it looks like Earth, despite a very big difference: Complex life forms have existed for billions of years on Earth, while Mars never

  • Divining Ice on Mars Through Time
    The spectacular features visible today on the surface of the Red Planet indicate the past existence of Martian glaciers, but where did the ice come from?

  • Mars Getting Drier and Drier
    Geologic features at the Opportunity landing site on Mars were formed not by a lake that evaporated but by constant strikes from meteorites, say two Arizona State University geologists.

  • Chemistry Says… Mars Not so Wet
    A region of Mars that some planetary scientists believe was once a shallow lakebed and likely habitable for life may not have been so wet after all, according to a new University of Colorado at Boulder study.

  • Opportunity’s Anniversary
    On December 12th, Opportunity celebrated one Mars year. A mission planned for 90 days has turned into an adventure that's lasted nearly two Earth years! Opportunity has traveled over four miles and returned over 58,000 images, helping us see into our planetary neighbor's alluringly watery

  • Radio Free Mars
    University of Iowa Space Physicist Don Gurnett and his UI colleagues report that a scientific instrument aboard the European Space Agency's (ESA) Mars Express spacecraft is working perfectly and that its data have so far revealed that Mars' ionosphere -- part of the upper atmosphere
