Mars Soil Appears To Be Able To Sustain Life

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.'"

    WASHINGTON -- NASA has submitted funding proposals for a new Mars mission, scheduled to launch in 2012. The mission will entail a new Mars lander called the Advanced Series Polymorphic Asparagus Research Automated Growing Unit Seedfarm, or ASPARAGUS, and is expected to grow several varieties of asparagus in martian soil.

    "[We] might be able to grow asparagus in it really well... It is very exciting for us" says Sam Kounaves, mission planner for the new endevour.

    The lander will be expected to gather soil and deposit it into a 'grow-op' like container, where asparagus seeds will be added to the mix. "We just don't know what will happen after that, it will be very exciting to watch the developments unfold over subsequent weeks." he adds.

    Included in the lander will be a CD filled with asparagus recipies for future astronauts of the first manned Mars mission, planned for 2050. "The CD will contain dozens of recipies all featuring asparagus as the main ingredient. Things like boiled asparagus, steamed asparagus, steam boiled asparagus, fried asparagus, and even just plain asparagus!" says Angela Schmidt, the mission's asparagus habilitation expert.

      I'm perpetually amused that folks whine how we can't replace an old-growth forest or rainforest but terraforming a planet, hey, no problem there. All you need to do is sprinkle a little spores and fairy dust and boom you have Earth II, except without all the people mucking it up...

      You asked the question and answered it at the same time. Life is very resilient to most anything short of more aggressive life. The old growth forests actually require less effort to fix than to kick-start mars. All you have to do is leave them alone for awhile and they would recover on their own. Keeping people from continuing to drag them down further is the trick. Mars has the edge here in that it's very hard for US to screw it up.

      It's more economical to spend $500mil to start an ecosystem that will maintain and develop itself without further interaction, fertilized only with time, than to spend $100mil every few years trying to keep fixing up what people keep breaking, and still continue to lose ground.

Science@NASA even did a story on our genetically modified plants that we proposed sending to Mars.

    For the record, Rob Ferl was quoted in an old CNN article recently cited in a previous Slashdot comment

    "I have no doubt what we can get plants to survive on Mars. When we do, we will have shown that Earth-evolved life is capable of thriving in distant worlds, and we will have set the stage for human colonization," Ferl said.

    My understanding is that the principal cause of atmosphere-loss on Mars is not its lower gravity (it was able to retain its atmosphere early in its life) but its lack of a good magnetic field.

    Mar's gravity has remained constant over the eons, but it has lost most of its magnetic field... which stems from its smaller size (Mars lost its internal heat and now its iron core is not liquid, thus no more magnetic field). Earth being bigger was able to retain its internal heat and still has a liquid iron core = still got a nice magnetic field.

    It is thought that having a decent magnetic field blocks solar wind, which strips away atmospheric molecules.

MECA detected the presence of magnesium, sodium, potassium and chloride but no carbon, the crucial ingredient necessary for life on Earth (alright, silicon might also work). Interestingly, JPL tells us that the mineral content of the soil is not much different from the upper dry valleys in Antarctica. What Phoenixâ(TM) wet chemical analysis shows is that there is no life in the soil sample tested by MECA. The Phoenix Lander's follow-the-water strategy for searching for organic compounds is, however, exactly the right strategy for NASA to pursue. Here's a hint, if NASA could land the Phoenix Lander on Enceladus or Titan or anywhere else in this sun system, the test results would likewise show that there is no life in this sun system other than on Earth.
