BOLD Plan To Find Mars Life On the Cheap
techfun89 writes "There is a BOLD new plan for detecting signs of microbial life on Mars. The nickname is BOLD, which stands for Biological Oxidant and Life Detection Initiative, would be a follow-up to the 1976 Mars Viking life-detection experiments. 'We have much better technology that we could use,' says BOLD lead scientist Dirk Schulze-Makuch, with Washington State University. He elaborates, 'Our idea is to make a relatively cheap mission and go more directly to characterize and solve the big question about the soil properties on Mars and life detection.' To help figure out the life-detection mystery, Schulze-Makuch and his colleagues would fly a set of six pyramid-shaped probes that would crash land, pointy end down, so they embed themselves four to eight inches into the soil. One of the instruments includes a sensor that can detect a single molecule of DNA or other nucleotide."
...who pictured Stargate when they read this?
Because there is bugger all down here on earth
Just run this as a joint mission between the US and the EU, problem solved.
Looks more like an all-caps plan to me.

The B.O.L.D. program hinges on detecting oxygen exchange
What if the life form on Mars uses N2 instead?
Muchas Gracias, Señor Edward Snowden !
...pretty much the plot of WALL-E?
Why doesn't a single one of these missions to Mars have an on-board optical microscope? Wouldn't that "just work" to detect life? Instead they carry chemical analysis setups that return inconclusive or difficult to interpret data regarding life.
Is it a technical limitation?
but I'm sober. How is it that life as we know it, consciousness, sentience, etc. is not enough? Think about it. Same universe. Same galaxy. Isn't life (as we know/call it) even in ONE place... enough? Beyond amazing, beyond impossible, totally and utterly improbable... yet here we are! So we get to mars and find a small pond of goo with some amino acids and proteins in it. So what? What's the big deal?
FTFS: "One of the instruments includes a sensor that can detect a single molecule of DNA or other nucleotide."
I wonder how many DNA molecules the probe might encounter on its way to Mars.
Set your phasers on "funky"!
They should make a seventh probe, and aim it at the http://en.wikipedia.org/wiki/Valles_Marineris. It's kilometres deep so the atmosphere down there ought to be thicker (it's certainly more turbulent). Assuming Mars once had a thick atmosphere and running water (which seems to be the prevailing consensus) then it seems to me that the place that environment and any possible inhabitants would have been preserved longest is in the Valles.
Unless, of course, this huge crack in Mars was the epicentre of some great event that stripped away the atmosphere in the first place...
a set of six pyramid-shaped probes
So that's what the title of the Doctor Who episode was referring to! I wonder if the probes will locate Sutekh.
Mars may be smaller than Terra, but it's still an awfully big place. Even if life exists or once existed on Mars, there's no guarantees its presence would leave a mark everywhere. Six immovable probes might find nothing and STILL not answer the question. The only way we get a useful answer at all from just six bullets fired into the dunes is that one of them actually finds something; if they find nothing it still doesn't disprove the presence of life.
It's great that the people behind this want to make names for themselves, but we need to think - and plan and budget - much bigger than this if we truly want a definitive answer. This plan with a spaghetti western budget won't give us one. It's essentially a waste of time. Bold, yes, but also pointless where the stated goal is concerned.
They are malfunctioning alien probes that landed upside-down.
Let's just hope we don't turn up any black monoliths.
Life, ultimately, boils down to the Four Fs: Fighting, Fleeing, Feeding, and Mating.

If it's anything like terrestrial life, it would.
But you are right in that this project will not give a definitive answer. There are many points of failure, the instruments can go wrong, the craft can introduce contamination to the sample etc. The only solid proof would be returning some soil sample to earth and finding the actual bacteria in it, but currently that's out of our reach both financially and technically.

An even better plan is to do a few simple experiments do help decide on what the big plan should be. If we can eliminate a few things first then it can make the big plan a whole lot cheaper.
No sig today...
Can you imagine if life on mars is discovered for real. I've never actually had any doubts that it exists. However it is a bit different once you get scientifical confirmation as result of extensive investigation, right? Pennsylvania Vacation
Even with all we do for planetary protection, I think it would be quite challenging to get something to Mars with no DNA, somewhere.
Sure, we all wear full coverage bunny suits when working on the spacecraft for that reason, but it's not like we're not breathing the air in the room, or there's test equipment has nooks and crannies, etc.
They do biological assays with swabs and cultures, as well as a LAL(Limulus Amebocyte Lysate) and ATP, but it's hard to get "perfect"
They should just embed a microphone, if they hear "ouch", they found life... well... alive up till then.

You may solo them, I prefer them in a group.
8 inches isn't enough.
Simulations have suggested that the UV bombardment of topsoil renders life surveys inaccurate down to around 2 metres. This is why ExoMars is going to have a 2m drill to get down there, anything on the surface even down to 8" is unlikely to survive.
Obama cut the Mars budget 38%, mainly in punishment for doubling the Curiosity lander cost. Another MAVEN orbiter is in assembly. After than no new Mars probes funded. Takes 5-9 years to plan, launch and execute a probe. NASA ended development of triple-probe sample return project and a joint ESA Mars-probe.
And this is before conservative republicans chop the budget, which they could do with a congressional majority next year.
All these plans to "find life" on Mars will inevitably result in humans putting life on Mars...which we will find later. How much "contaminants" do we put on a planet's surface before we realize that something will eventually slip through the cracks?
That they've been sending a fair number of landers to Mars over the past decade? There was little Sojourner, then Spirit, Opportunity and now Curiosity is one it's way there. And the tech changes between rovers. While the first three were solar, the latter is nuclear using an RTG meaning she doesn't need sunlight to do science. And Curiosity also has some AI features too which means she'll roam father over Mars surface.
After all of the newspaper headlines reading 'MARS IS DEAD, NO LIFE FOUND!' killed public interest of Mars back during the 70s after the Viking probes' questionable experiments, I'm not sure firing six small static probes at a sizable planet to look for DNA is a good idea. If history is any indicator it seems like a big risk to the entire exploration effort.
