beckerist writes “Scientists working on the Phoenix Mars Lander mission, which has already found ice on the planet, said preliminary analysis by the lander’s instruments on a sample of soil scooped up by the spacecraft’s robotic arm had shown it to be much more alkaline than expected. Sam Kounaves, the lead investigator for the wet chemistry laboratory on Phoenix, told journalists: ‘It is the type of soil you would probably have in your back yard, you know, alkaline. You might be able to grow asparagus in it really well. … It is very exciting for us.’”

cathector sends along a story from SpaceWeather.com on the discovery of water ice on Mars. “Scientists have figured out the mysterious white substance unearthed by NASA’s Phoenix lander on Mars. It’s frozen water. The breakthrough came last week when Phoenix’s stereo camera caught the substance in the act of disappearing. Bathed in martian sunlight for four days, the white substance sublimated — i.e., it transformed from solid to gas without passing through the liquid state. This is how water behaves on Mars…. Some readers have asked, how do we know the white substance is not frozen CO2 (dry ice) instead of frozen water? Answer: Phoenix’s landing site is too warm for dry ice. The average daily temperature is about -70 F while dry ice requires temperatures lower than about -109 F.” The animated GIF showing the ice sublimating is pretty nice too.

It’s only fitting that the glorious news of water ice on Mars was broke over Twitter this evening, via the Mars Phoenix lander’s own first-person ramblings. Apparently Mars Phoenix was keeping an eye on some white patches it uncovered the other day, only to discover they’d disappeared today. According to the scientist folk over at NASA, that means those white patches must’ve been ice, which dissipated once uncovered. Now Mars Phoenix still has the considerable task of uncovering more ice and sampling it, but the mission is ahead of schedule and NASA has already identified a hard patch of ground it wants to dig into. Congrats to Mars Phoenix and all the fine folks at NASA, now be sure to watch out for the cave-dwelling little green men!

CraftyJack writes “Bright white chunks in the trenches dug by the Phoenix Lander have disappeared, leading Peter Smith & co. to believe that the chunks were ice that has since sublimated.”

JoeRobe writes “Phoenix has successfully filled oven #4 of the Thermal and Evolved-Gas Analyzer instrument (TEGA). They have spent several days now vibrating the screen above the oven, trying to get a significant amount of soil sample into it. From the article: “[T]he oven might have filled because of the cumulative effects of all the vibrating, or because of changes in the soil’s cohesiveness as it sat for days on the top of the screen.” Either way, this is the first step toward getting some interesting data from this instrument.”

An anonymous reader writes “Nearly two weeks after its historic landing, the US Mars probe Phoenix has scooped up its first sample of Martian soil and begun analyzing it for water and organic compounds. The test dig made Sunday by the Phoenix Mars Lander’s 8-foot-long robotic arm uncovered bits of bright specks in the soil believed to be ice or salt. Mission controllers will send instructions to the lander to dump the sample into one of the Thermal and Evolved-Gas Analyzer (TEGA) ovens. The TEGA ovens, which are about an inch long and the diameter of a pencil lead, will heat up the soil samples and use a mass spectrometer to detect the gases that come off the samples, which will shed light on some of the materials in the soil, specifically those formed by the process of liquid water.”

The Phoenix Mars Lander has successfully deployed its robotic arm and tested other instruments including a laser designed to detect dust, clouds, and fog. The arm will be used to dig up samples of the Martian surface which will be analyzed as a possible habitat for life. A camera on the arm will allow pictures to be taken of the ground directly beneath the lander. The camera has already seen what may be ice, which was exposed when the soil was disturbed by the landing. The data collected by the arm will be compared to recent findings which suggest that water on Mars may have been too salty for most known forms of life.

spandex_panda writes “There are a few pictures of the Mars Lander on the ground, you can see its parachute and its heat shield a few kilometers away too. Theres a very cool looking picture of it floating down, actually captured while its in the air with its parachute out!” We also have a YouTube video all about the robot arm that will dig down and probably find a groundhog who we all hope will see his shadow.

Things are looking good for the Phoenix lander which touched down on Mars at 4:53pm on Sunday, May 25. The NASA nerds are reporting an almost perfect landing, with the spacebot tilted only one quarter of a degree. In fact, they’re claiming that this landing was “far smoother than any simulation or test that was ever done.” The lander’s north-pole location is measured at -106 degrees Fahrenheit and chock-full of life-preserving ice. Phoenix will chill on Mars for 90 days, sniffing soil and looking for frozen Martians in whatever form they may take. Now that Mars Oddyssey — one of its main communication uplinks — has passed over the lander, we have our first pictures, one of which is above. Nice work, guys!

Now that the solar panels have been deployed, the Mars Phoenix Lander has begun sending back pictures of the red planet to the hungry space geeks of earth. In just a few weeks the claw will deploy and they’ll start digging a hole. The scientists expect to use the dirt to construct a little sand castle which they will defend with several GI Joe action figures, and a bald barbie stolen from their sisters. Oh, and maybe find water or bacteria.

Iddo Genuth writes “Precisely at 7:53PM EST, the “Phoenix Mars Lander” touched-down on the desert-like surface of Mars. Since its launch on August 4th, 2007, the spacecraft has covered more than 680,752,512 kilometers, traveling at average speeds of around 120,000 km/hr. Upon arriving at its destination, the Phoenix will begin its exploration of our intriguing neighbor planet, in a mission to help astronomers resolve at least some of the many questions regarding Mars. The key question remains: can the Red Planet support some form of life?” Hella grats to our nerd brethren- you looked great on the Science channel. Yes I’m watching this live. Can’t wait to see what happens next.

AFP has a good summary of the pre-touchdown jitters the Phoenix Mars Lander crew is living through. The spacecraft has been under way for 10 months. If the landing goes according to plan — and only about half of the three dozen such attempts have — mission controllers at the University of Arizona will receive radio signals from the Martian surface at 23:53 GMT. Here’s the Mars mission home. You can (in theory) track the lander here, but at the moment the JPL Solar System Simulator is “experiencing technical difficulties.”

Suit up, space nerds, because the Phoenix lander is mere hours away from touchdown on Mars, and NASA’s blowing this thing out. Not only will you get a live video feed from their site, but apparently Mission Control ops will be liveblogging the touchdown and ensuing alien encouners / totally boring rock digging. Festivities kick off at about 6:00pm ET, prepare to set faces to stunned.

coondoggie writes “Turns out that the surface of Mars is stiffer and colder than previously thought. New observations from NASA’s Mars Reconnaissance Orbiter indicate that any liquid water that might exist below the planet’s surface and any possible organisms living in that water would be located deeper than scientists had suspected.NASA made the discovery was using the Shallow Radar (SHARAD) instrument on the Orbiter, which revealed long, continuous layers stretching up to 600 miles or about one-fifth the length of the United States. The radar pictures show a smooth, flat border between the ice cap and the rocky Martian crust, NASA said. On Earth, the weight of a similar stack of ice would cause the planet’s surface to sag. The fact that the Martian surface is not bending means that its strong outer shell, or lithosphere, a combination of its crust and upper mantle, must be very thick and cold.”
