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.'"
It would probably lead to a very smelly planet.

Let's hope the lander doesn't break down before next year's asparagus season.
You might be able to grow asparagus in it really well. ... It is very exciting for us.
And I thought I didn't get out much.

TFA refers to a 1 cubic meter sample (35 cubic feet). That is one sweet lander...
Lichen, although don't beat yourself up about being unable to find that information despite having the totality of human knowledge at your fingertips. Your mother probably drank a lot during pregnancy.
If you were blocking sigs, you wouldn't have to read this.
So nothing originally from Earth, then...
I like to place meaningful quotes in my sig, so people will know that I know what meaningful quotes are.

Some quotes...
Preliminary results showed the soil had a pH between 8 and 9, researchers said. A pH less than 7 means the solution is acidic, while a pH over 7 means it is salty. Phoenix also detected the presence of magnesium, sodium, potassium and chloride in the mixture.
"It's typical of the soil here on Earth minus the organics," Kounaves said during a teleconference from Tucson, Ariz. ...
The heating experiment, which was designed to look for organics, did not yield conclusive evidence of carbon. Scientists planned to study another soil sample taken from further below the surface.
Martian pot is what I'm waiting for. I'm sure it would be outta this world.

I can see the headlines now in all the papers, when this quote goes mainstream;
TOP SCIENTIST CLAIM MARS SOIL SUPPORTS ASPARAGUS LIKE LIFE FORMS!
Just more evidence that Big Asparagus has co-opted our national science agenda.
The problem with having the totality of human knowledge at one's fingertips is the necessary base knowledge. I know nothing about plant life, beyond that I need to mow the lawn every so often. I wouldn't have known to look up lichen as a possible candidate for growing on Mars. I thought lichen was like moss, and needed darkness and damp conditions.
Admit it. You post strawman arguments as AC so you get modded Insightful for refuting them, rather than Troll
Has everyone forgotten Mars has no ozone layer? The soil may contain the necessary minerals and other nutrients, but it's baked under UV rays and (last I heard) full of peroxides and other unfriendly chemicals as a result. Starting with plants is putting the cart before the horse; we should be thinking about extremophiles if we're serious about this. And would it be ethical?
~Eien no Inori wo Sasagete~ Searching for my Hatsumi...
It says that lichen still needs water to grow, it can just manage to survive without it for long periods of time. If there is no liquid water available on mars, the lichen would die eventually.
Farnsworth: Well, in those days, Mars was just a dreary uninhabitable wasteland. Much like Utah. But unlike Utah, it was eventually made livable.
Well, the *soil* might be capable of supporting Asparagus, but the seeds might not like the temperature, atmosphere, or ambient radiation.

After all, Mars and cocoa go together like IBM and genetic sequencing.
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.
Can you imagine? You get the munchies, and all there is to eat is asparagus? Ugh.
The ethical concerns have already been addressed. If the martians don't like our plans, they can file a formal complaint. The plans will be properly displayed for a sufficient duration in the bottom of a locked filing cabinet, stuck in a disused lavatory with a sign on the door saying 'Beware of the Leopard'.
The laws of probability forbid it!
Ok so how many asteroids do we need to crash into Mars to give it some greenhouse gases and an atmosphere similar to Earth's?
You'll want to be crashing comets into Mars, not asteriods. After all, what is crashing a rock into Mars going to do, apart from adding a new crater? Crashing a couple of megatons of CO2, H2O, and other gasses into Mars, well that's a different story. Not only do you get your brand new crater, but you add a couple of megatons of C02, H2O, and other gasses to the atmosphere.

Lichen and high altitude soil bacteria were my first thoughts as well.
Knowing the right questions to ask has always been more valuable than a large amount of rote knowledge when it comes to problem solving. Failing to teach this kind of skill is one of the great weaknesses of our modern school system. Rote memory is dropping into an even less important role as the information age progresses, even as public schools face more and more standardized tests as their educational benchmark. All that said, in a social world, grace and courtesy can play almost as much of a role in getting your ideas heard as having the right answer.
We are all just people.
GP may not be polite, but he's right. Lichen are the best adapted plants on Antarctica. And Antarctica is the closest Mars like environment you get on Earth, dry and cold. Some Lichens survive there with a few hours photosynthesis per year.

The entertainments you call fitting for adults strike me as juvenile pursuits. I would never seek to make it illegal for you to pursue them, but please clearly understand, I will never accept your claim that these interests make you a more mature adult human being.
Bringing about the birth of living worlds from previously dead worlds may be an impossible dream, as you claim, but the beauty of its potential is stirring enough to make it a worthy goal for a mature intelligent species.
If we fail to achieve this goal on Mars, we can and should find other planets where it can succeed. If we also fail to do that, it will be because we allowed ourselves to be distracted by short term pleasures such as those you describe, or because we followed your siren call to pour all our resources into repeatedly failing "solutions" for perennial problems such as poverty or disease. By all means, let us continue trying to solve humanity's problems on this planet. But don't use that as an excuse to shut down all space exploration efforts.
I care about humanity more deeply than you seem to be able to imagine. I care enough to want a future for humanity that extends beyond the lifespan of any single planet, beyond the lifespan of any single star system, and if possible, beyond the lifespan of any single galaxy. How is this any less mature than the desire of parents to hope their children and grandchildren might continue to prosper for many future generations?
If we fail to secure such a future for our descendants, the end result might very well be a sterile, dead universe, where nobody else will ever again have the chance to enjoy sex, skydiving, skiing or anything else adults do for excitement.
Bringing Mars to life may be so difficult it approaches the impossible. But it may be the best place to take the first step toward opening up the universe for humankind, and that makes it worth the effort.
I don't lichen asparagus anyway . . .

To Mars, Again!
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.
The $480 million project is expected to be greenlit later this year.
Murphey's fighting Occam, and we're in the stands.
I think the news here is that you would not have to bring native soil to Mars if you wanted to farm. Yea, you would have to farm under a dome but at least you don't have to transport a few tons of topsoil!
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.
