Lights Out for the Phoenix Mars Lander

It was a good run but NASA has decided to discontinue efforts to reestablish contact with its Phoenix Mars Lander.

In a statement put out on Monday, the Jet Propulsion Laboratory said that the NASA's Mars Odyssey orbiter, which flew over the landing site 61 times, had failed to detect any transmission emanating from the vehicle. Three other listening campaigns involving other attempts to establish communications similarly proved unsuccessful.

NASA said that an image taken from an orbiting spacecraft indicated that the vehicle, thought to be near the Martian north pole, had suffered severe ice damage to its solar panels.

The lander arrived on the red planet on May 25, 2008. Perhaps its most lasting legacy was the discovery that Mars featured diverse wet environments over the course of the planet's history. What's more, NASA said that the Phoenix had returned more planetary data than all other Mars missions combined. Among the Phoenix's other achievements, the agency flagged the following:

  • Confirmed and examined patches of the widespread deposits of underground water ice
  • Identified a mineral called calcium carbonate that suggested occasional presence of thawed water
  • Found soil chemistry with significant implications for life and observed falling snow.
  • Discovered perchlorate, an oxidizing chemical on Earth that is food for some microbes and potentially toxic for others
Photographs released today by NASA show two images of the Phoenix. The above shot, taken in 2008, shows a couple of relatively blue spots on either side which correspond to the lander's clean circular solar panels. NASA said that the dark shadow in the 2010 image might  be the lander body and eastern solar panel, but that there was "no shadow from the western solar panel."

That little droid did some good work. Now that the martian winter has torn off a solar panel it joins the ranks of lunar camps and the speeding Voyager missions as exhibits to human ingenuity. Perhaps someday tourists will stand a few feet away behind art deco railings and a plaque and snap holographic photos to take home. I so much prefer this sort of news over Lohan's ankle bracelet and the indignant rants of those who feel the ornate lines of political correctness have been crossed by someone telling it like it is. Now, let's get James Cameron's 3D cameras to Mars!

My money is on Marvin the Martian. Phoenix was probably getting too close to finding his hideout. At least the rovers are still in contact, even though one is stuck. Those little troopers lasted WAY beyond expectation!

Makes you wonder if it took a hit and, minimally, had one of its solar panels eliminated.

Agreed, Tool.

It outwitted, outlasted and outplayed all its predecessors.
