Phoenix, Gone But Not Forgotten

Posted on January 9, 2009 | 0 Comments

Great stars don't die, they just fade away.

It's been almost two months since NASA lost contact with the Phoenix Mars Lander, which had been studying icy soils near the red planet's north pole.

As summer moved into fall, sunlight began to fade and temperatures dropped too far for the lander to keep up operations, bringing the just over five-month mission to a nominal end.

One thing that's been made clear is that 2008 was the summer of the Phoenix.

Will the Phoenix Rise Again?

Posted on October 29, 2008 | 0 Comments

Late last night the Mars Phoenix Lander put itself to sleep after experiencing a malfunction brought on by its deteriorating power supply.

The craft also unexpectedly switched over to its backup electronics and shut off one of its batteries.

The news was surely a disappointment, but not entirely a surprise, for NASA engineers, who had been expecting problems with the rugged lander right about now.

That's because the Martian arctic is moving into fall, and as the days get shorter, poor Phoenix has been losing its fire [in the form of sunlight to power its instruments].

It's not just the scientific equipment that needs power.

Mars is pretty frigid even in summer, and right now it doesn't get much warmer than -50 degrees Fahrenheit (-45 degrees Celsius) during the day, with overnight temperatures plummeting to -141 degrees Fahrenheit (-96 degrees Celsius).

Let It Snow [on Mars]

Posted on September 29, 2008 | 0 Comments

NASA's Phoenix Mars Lander has seen snow falling on the red planet!

One of the probe's atmospheric instruments detected ice crystals coming from clouds about 2.5 miles (4 kilometers ) above, although the flakes seem to have vaporized before they reached the ground.

This probably isn't a huge surprise, as we already knew Mars has glaciers and ice caps that grow and retreat with the seasons, so it was a good bet it still has a hydrological cycle of some sort. Still, way cool to be potentially seeing it in action.

NatGeo News reporter Anne Minard has the full scoop, including other data from Phoenix that bolster Mars's likely history as a wet and wild world.

The news got me to thinking: Which other bodies in our solar system have snowfall?

After a quick roll around teh Internets, it seems the answer depends on how one defines "snow."
