Now that the glitches caused by the Martian soil's clumpy consistency have been shaken out, the Phoenix Lander has been able to cook up a few samples to test the soil composition. The preliminary results are surprising even to the chemists at work on the project: the soil is alkaline, and much more so than anyone expected. The analysis has found trace amounts of magnesium, sodium, potassium, and other elements similar to those in the soil on Earth. On first pass, Martian dirt appears to be non-toxic and laden with the basic nutrients necessary to support life.

A couple of days ago, it was big news when ice was found on Mars. Now, an upcoming study in the journal Geochimica et Cosmochimica Acta claims that the Martian environment was once wet enough to produce morning dew. This finding runs counter to the more widely accepted view that liquid water on Mars seeped up from the ground, rather than falling from the sky as precipitation.

NASA spent $420 million to send the Phoenix Lander to Mars last year. Festooned with state-of-the-art detection equipment, the rover's task was to scour the red surface in search of elusive Martian ice. And today, the NASA mission finally did uncover some extraterrestrial frost, and it did it with its simplest tool, a shovel.

For the past two weeks, NASA's Phoenix Mars Lander has been broadcasting a wealth of incredible images from its landing site in the Martian arctic. I've been refreshing the mission's raw photo stream obsessively—no little green men yet, just gorgeous panoramas and detailed closeups of the most foreign of all foreign lands. Being a bit of a camera geek, I was quite curious as to what kind of hardware was behind the action, and naturally, Phoenix has some pretty sweet gear on board to make it all possible.

In the first ever instance of a spacecraft photographing the landing of another craft on Mars, the Mars Reconnaissance Orbiter captured this incredible image of NASA's Phoenix Lander making its descent on Sunday. Phoenix landed successfully and has already begun transmitting images from its landing zone in Mars's northern polar region, where it will be conducting meteorological and geological surveys over the course of its three-month mission.

Just because NASA has two robots on the surface right now doesn't mean the landing of the Phoenix probe is a sure thing. At a news conference yesterday, NASA officials stressed that landing a spacecraft on Mars isn't easy: 55 percent of all attempts to do so have failed. Not to mention that the technique Phoenix will use to do so hasn't been employed in a while.
