  • Opportunity’s Spinning Wheel
    Mars rover engineers are using a testing laboratory to simulate specific Mars surface conditions where NASA's rover Opportunity has spun its wheels in a small dune. Careful testing is preceding any commands for Opportunity to resume moving to get out of the dune and continue

  • Boom, Temporary Bust
    The deployment of the second antenna boom of the Mars Express Sub-Surface Sounding Radar Altimeter (MARSIS)science experiment has been delayed pending investigation of an anomaly found during deployment of the first antenna boom.

  • Hints of Habitability
    Bernard Foing, Chief Scientist for the European Space Agency, provides an overview of the most notable discoveries made during the Mars Express mission, Europe's first trip to the Red Planet. In part two of this overview, Foing looks at how these discoveries could help pinpoint

  • Big Iron to Mars
    A large spacecraft destined to be Earth's next robotic emissary to Mars has completed the first leg of its journey, a cargo-plane ride from Colorado to Florida in preparation for an August launch. NASA's Mars Reconnaissance Orbiter (MRO) is an important next step in

  • Wading in Martian Water
    The European Space Agency's Mars Express spacecraft has been orbiting Mars for over a year. While the high resolution images of the planet's many craters, volcanoes, and other features get the most notice, the spacecraft's seven instruments have also gathered large amounts of data about

  • Has Spirit Found Bedrock in Columbia Hills?
    Since arriving at the Columbia Hills, Spirit, one of the Mars Exploration Rovers, has encountered some mysterious phenomena. The rover's right front "arthritic" wheel that plagued Spirit's 2-mile trek across the plains is now suddenly working perfectly.

  • State-of-the-Art Mineralogy for Mars
    Aiming to nail down whether Mars could have nurtured life in the past, the Mars Science Laboratory will live up to its name, with a state-of-the-art internal chemical and mineralogical laboratory. The rover will pick up rocks, chew, swallow, then analyze the minerals in detail

  • Tornado, Signs of Martian Spring
    At the Spirit rover's site in Gusev Crater, the appearance of a mini-tornado, or dust devil, is a sign of spring. As the midday heat peaks, so the whirling winds of this dusty crater bed. Dust devils are familiar to observers in the American Southwest

  • Knocked Off Its Axis
    Since the time billions of years ago when Mars was formed, it has never been a spherically symmetric planet, nor is it composed of similar materials throughout, say scientists who have studied the planet. Since its formation, it has changed its shape and thus the

  • Next to Rove Mars?
    European space scientists have strongly recommended a mission equipped with a Rover as the next scientific mission to Mars as part of the European Space Agency's Aurora programme of planetary exploration.

  • Flying a Science Lab to Mars
    How do you follow a flat-out success like the Mars Exploration Rovers, still cruising Mars after all these months? By thinking "bigger and better." The Mars Science Laboratory, currently scheduled for launch in 2009, will land a rover three times as massive as Spirit or

  • Rovers Happily Not to Go Away Soon
    NASA has approved up to 18 more months of operations for Spirit and Opportunity, the twin Mars rovers that have already surprised engineers and scientists by continuing active exploration for more than 14 months.

  • The Martian Mortal Coil
    While the Spirit and Opportunity rovers continue to investigate Mars, scientists are already testing more advanced rovers for future missions. Nathalie Cabrol, a planetary geologist with NASA Ames and the SETI Institute, and a member of the Mars Exploration Rover team, has been testing

  • Medusa on Mars
    Images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show part of the Medusa Fossae formation and adjacent areas at the highland-lowland boundary on Mars.

  • Martian Fire and Ice
    Mars isn't as sleepy as scientists suspected. An international research team, which includes Brown University planetary geologist James Head, has found evidence of recent glacial movement and volcanic eruptions in 3-D images from the Mars Express mission.
