The first images from the Phoenix Mars Lander have confirmed that the solar panels needed for its energy supply unfolded as planned and that masts for its camera and weather station are in position.
A successful touchdown late Sunday was followed by the first pictures about two hours later. More images are expected Monday evening.

The pictures "show a beautiful Martian landscape," Brent Shockley, Phoenix configuration and information management engineer, wrote in his blog Sunday night.
The landing of NASA's machine concluded a 422-million-mile journey that began last August. The Phoenix is on a three-month mission to determine whether ice below the surface ever thaws and whether some of the chemical ingredients needed for life are preserved in the soil.
"It's liquid water we're looking for," Peter Smith, of the University of Arizona at Tucson and principal investigator for the Phoenix mission, said during a press conference Monday on NASA TV. "Does the ice melt?"
Smith noted that the ground looks like the "active surface of the Arctic regions of Earth." Cracks in the soil show that surface is "active" because no dust or sand has filled in the cracks.
One particularly interesting photo comes from the NASA's Mars Reconnaissance Orbiter, which actually captured the lander as it was parachuting to Mars in the last leg of its long journey. Barry Goldstein, project manager of NASA's Jet Propulsion Laboratory, called that image "spectacular." The orbiter will act as a middleman communicator between the Phoenix and NASA.
At some point over the next few days, the lander's 7.7-foot robotic arm is scheduled to begin functioning. The robotic arm is set to collect the first soil samples in about a week.
The lander is expected to function for about 90 days with energy generated by the solar panels.
"Seven minutes of terror will be followed by three months of joy," a jovial Goldstein said during Monday's press conference, referring to the seven minutes of the final stage of landing.
But it is possible that the lander will function longer.
"We are going to operate till Mars freezes over," Goldstein joked.
Here is one of the octagonal solar panels, which open like handheld, collapsible fans on either side of the spacecraft. Beyond this view is a small slice of the north polar terrain of Mars.

Cool shot of the chute and payload.. Thanks!
ping. Thought your list would like the image.
That’s really cool
If that’s not cool, then I don’t know what is.
Why is this the case? I would think that Solar Panels would provide power as long as they functioned...
In 90 days the CO2 in the Martian atmosphere will start to sublimate from gas to solid. Shortly thereafter it will be encased in 1m of solid CO2.
“Phoenix is on a three month mission.” Of course, the last two three month mission to Mars are still working and returning data so, we’ll see how long this one lasts. Of course, since Phoenix is near Mar’s North Pole and is solar powered, it will be out of commission when the sun goes down for a few months. But, when the sun comes up again, hopefully Phoenix will be able to re-power itself.
See reply #8.
Didn't kill Han Solo, so maybe Phoenix will be OK too. ;)
Interesting geometric patterns in the landscape. Wonder what they reveal?
One of the scientists involved said that the lander will be covered with a meter of frozen CO2. Powering up after that might be iffy.
Hey, it’s certainly worth a try to power up the lander after the sun is due to rise again. Probably wouldn’t work, though. I was just reading about the different instruments on board the lander, and one of the interesting ones is the robotic arm. The arm will be arm to dig up to 1.6 feet down into the Martian soil. That’s pretty deep! We just might see liquid water on Mars for the first time...
agreed, they had to make a lot of calculations to make sure the MRO was flying over that particular place at that particular time to get that shot.. pretty good job all around on that run.
In addition to being encased in dry ice, Phoenix landed above the Martian Arctic Circle, and, just as on Earth, the Sun is below the Martian horizon during winter. This means that there is no electricity available to the craft from its solar cells, and the batteries cannot be recharged.
Personally I want to get a look inside the caves we now know exist on mars.
Hey, that is really good! An instant classic. Did you do it yourself? I love the "peace" sign. Perhaps you could do another where the large banner reads: "No War On Mars" or something along those lines. Another might relate to John Kerry's Vietnam Veterans Against the War and *their* version of the "Phoenix Project" .
