Group Plans to Bring Martian Sample to Earth

sm62704 (mcgrew) writes "New Scientist has a story about IMARS (the International Mars Architecture for Return Samples) planning to bring samples of Martian soil to earth. The robotic mission would be a needed precursor to manned trips to the red planet. Also, international cooperation is necessary since the US has already nixed bankrolling manned Mars missions."

I wonder if we should.

[AltGrendel]

With all the movies and sci-fi books out there that have reasons why we shouldn't, maybe we should leave well enough alone.

Re:I wonder if we should.

[CRCulver]

Agreed. I fear Earth will soon face an epidemic of The Andromeda Strain . After all Crichton was a doctor, he should know.

Re:I wonder if we should.

[morgan_greywolf]

Agreed. I fear Earth will soon face an epidemic of The Andromeda Strain . After all Crichton was a doctor, he should know. A lot of what's in Crichton's work is pseudoscience at best. Take Jurassic Park. None of the DNA that has been captured from dinosaur fossils is in good enough condition to produce a clone ... and all likelihood no sample will ever be found that could be used for cloning. It's also mentioned that all life is inherently female and that it's only the introduction of the Y chromosome that makes a zygote male. Not quite. What really happens is that there are X sperm and Y sperm. So, from conception, a zygote already carries the sex chromosome. Now it is true that the Y chromosome doesn't get activated until sometime after development when a certain hormone gets introduced. The failure of the Y chromosome to activate is actually the cause of a rare but serious disease.

I've been reading Crichton's Next and I have to say that it's got some good science in there -- but there's a lot of pseudoscience in there too.

So, I wouldn't take The Andromeda Strain as gospel for what might happen. Samples taken from the moon obviously haven't wiped out life on Earth, why should we believe that samples taken from Mars would?

Re:I wonder if we should.

[BigDumbAnimal]

Current cloning technique requires a living female of the species to be cloned.

Re:I wonder if we should.

[TheCRAIGGERS]

Samples taken from the moon obviously haven't wiped out life on Earth, why should we believe that samples taken from Mars would?

That is horrible logic. Even if we ignore the fact that mars and the moon have some radically different environments, what you basically just said is "If I can stick my arm in this cow's mouth and not get bit, then I should be able to stick my arm in any animal's mouth without worry of getting bit.

There is a lot of stuff out there we haven't seen. And it's entirely possible that some of that stuff is capable of killing us.

Re:I wonder if we should.

[morgan_greywolf]

Well, technically speaking the dinosaurs weren't "cloned" in the book -- they used transgenic techniques. I'm not entirely certain if the DNA has to be living, but these techniques are very complicated and often do not succeed until many, many attempts have been made.

Re:I wonder if we should.

[SilentBob0727]

What really happens is that there are X sperm and Y sperm. Actually, XY is only what happens in most mammals. There are at least three other prominent sex-determination systems among biological organisms, including X0 (females have two X's, males have one), ZW (W encodes femaleness), and Haplodiploidy (gametes develop into males, zygotes into females): See here for more information.

Reptilian gender is environmentally, not genetically, determined. Of course, dinosaurs weren't strictly reptilian. Nevertheless, Crichton was not describing the XY system. He was using his knowledge of exotic sex-determination systems that aren't commonly known among laypeople in order to spin a good yarn.

I do agree his work is rife with pseudoscience. But this one isn't that inaccurate.

Re:I wonder if we should.

[morgan_greywolf]

Well, here's someone who makes your case for you, but the real question is how will we know what will happen unless we find out? There would be, I'm sure, protocols in place to avoid contamination problems. If Jonas Salk hadn't injected himself and his family with his polio vaccine, polio might be quite a bit more rampant today.

Re:I wonder if we should.

[TheCRAIGGERS]

I'm not saying we should stop exploring and studying. But sticking our head in the sand and ignoring the possibility of finding something that could kill billions of people is not the way of going about it. Thankfully, I'm sure the people working on this are going to try their best to keep it separate from our environment, if for nothing else than to avoid ruining their experiments.

Re:I wonder if we should.

[babblefrog]

I'm trying to imagine how an organism that evolved (or was intelligently designed) for the cold, dry surface of mars would find our warm, wet insides a hospitable environment.

How To Beat Congress's Ban Of Humans On Mars Which references another slashdot story:

A Thomas search indicates the status of the bill as: Last action: 11/8/2007 Resolving differences

before that?

Anyway, I wasted 20 minutes finding several sources that contradict the claim that congress has "nixed" or otherwise banned NASA from researching a manned mars flight. Thanks for your helpful and constuctive criticism of a simple request that someone making a claim actually cite some fucking facts.

Re:uh?

Are you OK? I found references that clearly don't support the statement I am asking to be cited. There is vague reference to wording in an appropriations bill that may or may not pass as is, that may or may not allow research into a manned mars mission to go forward.

Glad to see that the slashdot editors are still busy keeping their Aerons warm.

Other worth subjects

[Kranfer]

While mars is a worthy subject of return samples, I also believe that more return samples from coments/asteroids would be of more value for figuing out if life is out there. As we all know from previous /. articles, bacteria can survive on space craft, and we are worried about bringing such life to places like mars. However I think Europia and Io would be awesome places to check out for life. But thats just me... if it were up to me, I would say do what the Governor of CA said on the Howard Stern Show a few weeks ago... get a bunch of rocket engines and move the earth a few inches more away from the sun to get rid of global warming... but hey what do I know?

Re:Other worth subjects

[Tablizer]

While mars is a worthy subject of return samples, I also believe that more return samples from coments/asteroids would be of more value for figuing out if life is out there.

If there is life in comets or asteroids, it would probably be deep down in order to hide from cold and radiation. Thus, it would probably require expensive drilling. On Mars, one would only have to dig a few feet at the most.

But I think a bigger problem is the risk of contamination of Earth with a deadly disease that we have no immunity for from such returns. I agree that the risk is small, but it has the small risk of wiping us all out.

It's Robotic!

[FroBugg]

Also, international cooperation is necessary since the US has already nixed bankrolling manned Mars missions.

This is a robotic mission, so would be perfectly fine under the NASA funding rules. If you're pissed about the rule, go complain in the thread we already had about it. Don't inject it into stories where it has no real bearing.

The actual article itself contains this completely different and more appropriate explanation for the need for international efforts:

International cooperation in the project is important because it is likely to carry a global-size price tag. NASA previously backed away from its own plans for a sample return mission due to budget overruns in the space shuttle programme.

"It's not an inexpensive proposition, and the ability to share the technical challenges and the costs across nations is very important for the success of this," says meeting attendee Lisa May, NASA's lead programme executive for Mars sample return missions.

Re:It's Robotic!

[DerekLyons]

NASA didn't just back away because of cost overruns in the Shuttle program, but because the estimates of the costs of the sample return took off like a rocket. Partially because they kept finding new areas to gold plate, partially because they kept making it more complicated, and partially because it is freakishly complicated even when unadorned.
 
JPL is no better than the rest of NASA at estimating and controlling costs - they've frequently come under fire from both NASA administrations and Congress because of this.

Why?

[EvilGrin666]

Didn't the Viking Landers already do this?

Re:Why?

[FroBugg]

The Viking missions sampled soil on-site with the tools that were built into the landers. This mission is planning to bring samples to Earth, where we can perform much more detailed analysis with tools that cannot easily be sent to another planet and operated remotely.

Re:Why?

[s4m7]

Viking collected samples, but didn't bring them back to earth for human inspection. The popular view of the Viking programs was that the tests performed on the samples were inconclusive.

Re:Why?

[petermgreen]

as others have said the viking landers dug up samples and ran some tests on them but didn't bring them back.

The problem is that by the time you have hardened a sensor for space use, got it approved and then got it to mars it will probablly be over a decade behind the technology we have on earth and if you want to retest with better sensors you have to send a whole new mission.

By bringing the sample back here it can be studied with the latest equipment we have and we can retest as new equpiment becomes availible.

Re:Why?

[bcrowell]

The Viking missions sampled soil on-site with the tools that were built into the landers.
To amplify a little on what you said: the results from the Viking experiments were ambiguous. They set criteria in advance, and said, "If the experiment does X, it means there's life, otherwise there's no evidence for life in the sample." The experiment actually did X, but some other aspects of the results were different than anything that was anticipated, which made the entire thing hard to interpret. At the time, the official announcement was that the results of the experiment were negative, but it's still pretty unclear. It could have been weird soil chemistry, or it could have been weird microbes.

Send a Mars Rover and pieces to make a catapult

[Thanshin]

With about 0.35g, they may just send a Mars Rover with a mechanical arm and also send pieces to build a catapult. In six months or so, the rover builds the catapult and uses it to throw a piece of ground back.

The only problem could be the rover exceeding his expected lifetime thirteen times and burying us in Mars pieces.

Phew!

Right, we all know it's the US's job to supply the funding, while leaving the actual decision making to "international cooperation." You know, the old "we want to play, we just don't want to pay."

Re:Rocket engines

[jackpot777]

Mod parent for funny, even though I'm answering seriously...

Wouldn't the power output needed to move 60,000,000,000,000,000,000,000 Newtons of mass (maybe I should have used tons ...just knock four zeroes off, that's close enough) just pump so much climate-changing stuff in the air it'd defeat the purpose?

By the way, a Saturn V rocket weighs around 3,000 tons (30 thousand Netwons, approximately). That's just for comparison.

If we used enough rockets to make a sizeable difference to Earth's orbit (which we don't have the fuel for, or the raw materials to build the rockets), the heat would be incredible. That's assuming that one of the rockets doesn't have a fault and blow up, leading to a firestorm that cooks the planet enough to evaporate the oceans.

I do like the idea of a rocket store, though.

Re:Rocket engines

[SilentBob0727]

I hate to nitpick (*sigh* no I don't), but the Newton is a measure of force, not mass, and doesn't make a whole lot of sense when describing a planet... What would that be, the gravitational force Earth exerts on itself? That would be zero.

Re:Rocket engines

[jackpot777]

I was going to use kgs, but then I got to thinking that the mass of the Earth would still make gravity at 9.8 m per second squared. But you're right... that would be the force of the Earth if weighed on, erm, the Earth. Knock off a zero, and pretend I said kilos.

[gowakuwa]

What do they expect to find?
Even if they found life, and that would be extremely unlikely, even if it is there, due to the life-unfriendly conditions(no heat, no organic medium) at the surface, they would have to dig and dig in the correct place. Then, when they had their rocks dripping Andromeda virus how would they know if it's dangerous to humans(or other earth life, I wouldn't like it wiping out Saccharomyces cerevisiae) without releasing it in the wild? They would need to check their interactions in vitro with every lifeform in the world to ensure 100% safety. And even then it could evolve.

Re:I wonder...

[FinestLittleSpace]

Most of the time they are looking for /evidence/ of life, not necessarily life itself. Shoving a rock in a spaceship for a year or so is a pretty good way to kill any life that was in it as it is....

It'd also be handy just to check out the exact composition of the rock/soil.

Oh noes! I'm afraid of the unknown!

[Anonymous Coward]

Let's hurry up and go already.

[evanbd]

The robotic mission would be a needed precursor to manned trips to the red planet.

No, it wouldn't. We know enough about Mars to send a human or three there on a mission now, especially with a plan like Mars Direct. (Short version of plan: send an automated small chemical plant there with a hydrogen cargo. Turn the hydrogen plus martian CO2 into methane + oxygen. When the return vehicle is fully fuelled, send the human crew along on the next ship. They don't launch until they have a confirmed return ship ready, so if the hard part doesn't work they don't go. It needs two launches with payload capability roughly on par with either a Saturn V or a Shuttle stack converted to cargo use instead of flying the orbiter -- or an Ares V, roughly.)

Of course, sample return missions are interesting and useful in their own right. But don't confuse the issue; we went to the Moon without a sample return mission, we can do the same for Mars.

1. Yes, we could, until such point as the CO2 concentration in our atmosphere became unhealthy. I supose then we could all wear filters or live underground.

2. Of course!

3. Umm, yes, I was more thinking that you'd need to provide a consistent thrust but that the earth is rotating at high speed and it's not so simple as a result.

4. Ok, good, so pushing on one point on the crust (and of course moving the core) isn't going to cause massive changes to seismic patterns and pressures and drown half the planet in lava then?

5. At least you admit the possibility.

6. Hmm, become more energy efficient and look into non carbon-producing power sources OR engage in a highly, highly risky engineering project on a titanic scale, a feat unequaled in human history, which may just render the world completely uninhabitable...

I'd go for efficient/clean tach (which we're already able to do in a lot of ways) rather than that. Whilst the idea of a global human effort to buiuld a great big machine to move us further from the sun and save our skins is quite an uplifting proposal, it does seem to be both overkill and utterly ridiculous to build such a device rather than clean up our act a bit.

Re:Hmmmm.....

[_Shorty-dammit]

meh, I don't think there's any point in recycling, either. I mean, it's quite an uplifting proposal, but it does seem to be both overkill and utterly ridiculous to spend so much time, effort, and energy in recycling programs, when a relatively small chunk of land nowhere near any populated areas can have the entire world's garbage dumped in it for 1000 years with much less impact on the Earth, in terms of time, effort, and energy required to do so. But, hey, recycling makes jobs! So, yeah, I'm probably not the best person to be chatting with about this kind of thing, haha. So I'll just take my leave. Have a good day.

Re:Hmmmm.....

[Gorimek]

2. You just burn the rocket for an hour a day or so, when it's facing th Sun. That part is not the weakness of this proposal.

I'm sure this would work without an atmosphere. But inside one I'm not sure about the physics. Will the opposite force 'get stuck' and disperse in the air rather than result in a net transfer of momentum?

Re:Hmmmm.....

[SilentBob0727]

1. Yes, we could, until such point as the CO2 concentration in our atmosphere became unhealthy. And then we'd evolve to photosynthesize... I'm liking this idea better and better. All hail the plant people and their new reign of terror!

Just plain stupid (proposed) law.

[DougF]

From: http://www.thespacereview.com/article/1012/1

The House of Representatives version of HR 3093, the bill that determines NASA's funding for 2008, effectively bans the study of an entire planet:

Provided, That none of the funds under this heading shall be used for any research, development, or demonstration activities related exclusively to the human exploration of Mars.

The House committee report mentions the proposed prohibition: Finally, bill language is included prohibiting funding of any research, development, or demonstration activities related exclusively to the human exploration of Mars.

Now, this leaves a loophole large enough to drive an M-1 Abrams through, but it's still just plain stupidity.

Re:Just plain stupid (proposed) law.

[susano_otter]

What's so stupid about it? We have a long way to go, and a lot of other problems to solve, before it makes sense to spend lots of money on manned missions to Mars. A lot of what we need is going to have to wait for the next generation or two of technological advancement in materials science, nanotechnology, and micro-electronics. If we spent money on manned missions to Mars right now, it would probably all be wasted. New technology would obsolete our prototypes and shift the entire paradigm of the project, forcing us to abandon half-completed projects and start over from scratch.

Much better to focus our resources in other areas where the development cycles are a lot shorter and the financial risks a lot smaller, to solve some of the intermediate problems between our current capabilities and manned mars missions, and stimulate research and development of the intermediate technological advances between here and there, and then authorize a new spending bill when we're actually in a good position to accomplish a manned mission.

Besides, the thing has a loophole big enough to drive a tank through. I guess the moral of the story is that even when you try to please everybody, some jackass will still find an excuse to complain.

Re:Just plain stupid (proposed) law.

[DougF]

Ahh, the old "we can only do one thing at a time" argument. What problems should we solve before doing anything else? How about let's solve poverty first, no wait, let's solve health care and give everyone indefinite lives first, no wait, let's solve the energy crisis and all live at high altitude first. C'mon, the exploration of space has provided many times in return the investments made. Health, technology, safety, weather, archeology, forestry, aviation, farming, and industry have all made tremendous gains because of the space program. People like you thought the Wright brothers should've stopped fooling around with that useless contraption called an airplane over a hundred years ago and look what benefits we've reaped from the aerospace industry. The exact same phenomenon will occur with the Mars mission. There will be breakthroughs in power, communication, reliability, software, propulsion, and health-related areas all because we set ourselves a goal, that while hard, is not unachievable if we but set our minds to it.

Besides, we're not going to Mars tomorrow or the day after. We're going back to somewhere we've been before, the Moon. We'll learn from those trips how to work and live long term in space away from mother Earth. The Moon will be our stepping stone to exploring and exploiting the natural resources in the solar system. Right now, we are in the best position to plan and prepare for the next phase of manned missions. The assembly of the ISS is winding down, the Shuttle is retiring, no better time than the present to start the next phase.

Spending bills are only good for one or two years at at time. It's not like we have to fund the entire trip to the Moon (or Mars) in one budget.

And since when is attempting to stop progress trying to please everybody? Sounds like the bill was intentionally designed to make a very lot of people very angry...

EASY; Falcon9 heavy and Armadillo

[WindBourne]

Using a falcon 9 heavy (available sometime in 2011), combine with medium size armadillo, it should be possible to bring back samples. Falcon 9 shoots it there. uses aero-bracking. Followed by parachutes for landing (probably will require some use of the armadillo for the final descent. Allow a small rover to run around the site and gathter samples. Put it back on the armadillo. It then takes off and shoots for earth. Close to earth, it releases a capsule containing 1-2 tons of various samples, which parachutes back to earth. This could all happen by 2015 or even sooner.

Perhaps it is time for another x-prize.

Recycling costs less....

[Nursie]

...apparently, than creating fresh. That's the point, it's actually cheaper to be efficient than to ship everything to part of the planet you don't like. Not to mention that eventually you run out of new raw material for plastics.

But you've thrown me a bit there - I wasn't talking about recycling. Dumping rubbish, whilst wasteful, isn't anything much to do with global warming. Though recycling can, through its energy efficiency, reduce our carbon emissions a little.
