  • A Tale of Planetary Woe

    2009April 6, 2011

    Long ago, something calamitous happened to Mars, transforming a hospitable world into the apparently lifeless desert we see today. Many scientists believe The Red Planetlost most of its atmosphere, but how? A new NASA mission named MAVEN is specifically designed to answer that question.

  • Mars Surprise

    2000April 6, 2011

    In what could turn out to be a landmark discovery in the history of Mars exploration, scientists using data from NASA's Mars Global Surveyor spacecraft have observed features that suggest current sources of liquid water at or near the surface of the red planet. NASA scientists compare the features to those left by flash floods on Earth.
