Like a racecar in need of high-performance tires, the next rover to explore Mars needs a rugged set of wheels. Like the racing tires, the off-road wheels must perform flawlessly. Together with a rugged suspension system, they must be lightweight, strong, and agile enough to handle extreme terrain. takes a lot of drilling to prepare to use a drill 100 million miles away, beyond the reach of humans. The Mars Science Laboratory rover is wasting no time doing just that. With an industrial-strength drill, the rover will pulverize the inside of hard, volcanic rocks on Mars and study the powder.

NASA's Phoenix Mars Lander continues on course for its May 25 arrival at Mars. After targeting its certified landing site with a trajectory, or flight path, correction maneuver on April 10, the spacecraft's performance has been stable enough for the mission's operators to forgo the scheduled opportunity for an additional trajectory correction maneuver on May 10 and focus on the next such opportunity, on May 17.

A new online map lets visitors explore Mars’ past through a collection of high-resolution observations from one of the most powerful spectrometers ever sent to the Red Planet. Evidence of ancient bodies of water, flowing rivers and groundwater peeks out from beneath layers of hardened magma and dust—testaments to Mars’ progression through wet, volcanic and dry eras.

April 16, 2008

Though they're not attached to creatures of the deep, fins made of rock poke up above the surface and suggest past water on Mars. NASA's Opportunity rover took images of a thin fin on the edge of a rock in "Victoria Crater." The fin was rich in hematite, a mineral that often forms in the presence of water.

If you smacked a frozen chocolate bar on a table, it would break into bite-size pieces resembling the terrain in this Martian crater. To a planetary scientist, this pattern is a tantalizing clue that the ground once contained water ice. When the frozen terrain cracked, in some places the ice melted into flows chock full of sediment. Perhaps the ground is still filled with layers of near-surface ice.
