Mars Rover Solves Metallic Object Mystery, Unearths Another

SchrodingerZ writes "Last week the Mars Curiosity Rover spotted a shiny metallic-looking object in the martian soil. This week scientists have confirmed that it is plastic that has fallen off the 1-ton rover. However, the discovery of this trans-planetary littering has opened up another mystery for the science team. On October 12th the rover took a sample of soil from the ground, feeding it into its Chemistry and Mineralogy (CheMin) instruments for analysis, and a picture of the hole dug by the rover's claw revealed metallic particles in the dirt. The sample was subsequently dropped due to fears that particles from the rover had made it into the dirt. Further study now suggests that the metallic particles are actually native to Mars, as the photo reveals that they are embedded in the soil in clumps. In 2007 the older rover Spirit found evidence of silica for the first time, more testing will occur over the next few days to determine truly if this is again just Curiosity's littler, or something more profound."

So by "Unfortunately" do you mean that the only reason we should go to the incredible expense and risk of visiting other planets is for purely academic or intellectual purposes? Is there anything of actual value to our planet Earth that we can glean from pure knowledge (and knowledge alone) of Mars? Say we learn more about the history of Mars. Humanity applies that information in exactly what way to better our species or improve our planet in some way?

At the end of the day, for it to be worthwhile beyond the science that we are doing right this minute with rovers, there has to be something of value on Mars. Real, tangible value. Materials that are rare on earth, a stopover for energy to reach other parts of the Solar System and beyond, a low gravity place to make materials that we can't produce on Earth, or even a "lifeboat" for humanity - at the end of the day there has to be something a step beyond just knowledge for the sake of knowledge.

Re:Crossing my fingers

The advantage isn't taking metals back. It's using them on Mars. If there really is even just metallic iron, that'd be a HUGE benefit for colonization. Trivial to mine (scoop dust, blow over rotating magnetic collector), trivial to process (I once sketched out the resource chains to run a blast furnace on Mars and it's just staggering - if this is metallic iron and it's pure enough to be structurally sound if simply melted and cast, it'd be huge deal).

If it applies to metals other than iron, all the more the benefit. Anything you can do to reduce the massive resource chains needed by modern tech could be a godsend for actual colonization.

Well, it's a pretty big deal just to melt and cast iron when you're on a foreign planet with no life and CO2 for an atmosphere. And making modern useful things out of iron actually requires steel alloys, which means having other metals available and being able to control carbon content of the melt. When there's no fuel on the planet, that means you must use electric power. It takes HUGE amounts of power to run an arc furnace, and moderately use amounts to run an induction furnace. Millions of watts either way. That's a lot of solar panels to haul to Mars.

[FatLittleMonkey]

The advantage isn't taking metals back. It's using them on Mars. If there really is even just metallic iron, that'd be a HUGE benefit for colonization.

However, without trade, the colony will always be dependent on its parent nation. And that's not really a colony, it's just an outpost. A really expensive outpost.

The advantage with asteroids (and to some extent lunar development), is that you can serve other markets. Even if it's not cost effective to bring the product back to Earth, as long as it's cheaper than launching from Earth, there should be a small but growing market for in-orbit delivery. Starting with fuel, then air/water, then bulk shielding and crude structures, and developing through more complex manufactured materials. And each stage also feeds back on itself, if you can supply fuel cheaper than Earth-launch, you lower your own running costs, and make whole new activities possible in space which creates whole new markets...

Such a process, once started, should then develop naturally, with each stage paying for itself and creating a market for the next stage; without requiring constant funding through traditional space agencies. [Although it will also give space agencies more bang for their buck. As well as making space exploration easier to justify to the average voter, and the very average politicians.] Until one day you read about how many people permanently live in space, and you realise that we are finally genuinely out there.

Mars won't do that. It will always be a "program", a drain. Historically, colonies like that always fail.

So by "Unfortunately" do you mean that the only reason we should go to the incredible expense and risk of visiting other planets is for purely academic or intellectual purposes?

Nice strawman, there. I mean, it's good to know that to scoff at greed is equivalent to be interested in something "for purely academic or intellectual purposes". Perhaps the scoffing has something to do with the fact that greed as a motivator to do things has all sorts of very negative side-effects--economic bubbles are a big one. Or perhaps it has to do with the point that a view that moderation is a good thing and liable to produce much more desirable long-term results while greed tends to, in focusing on being an end unto itself, be an almost pointless exercise a lot of the time.

Is there anything of actual value to our planet Earth that we can glean from pure knowledge (and knowledge alone) of Mars?

That's a pretty good begging the question. If you don't view "knowledge alone" as something "of actual value to our planet Earth", then there's little point in asking the question because no response that could be given would be acceptable to you. It entirely ignores that there are people who do, obviously, see value in knowledge alone and that a trip to Mars focused on expansion of humanity into the cosmos would be more than a pure knowledge expedition and not a greed motivated one.

Say we learn more about the history of Mars. Humanity applies that information in exactly what way to better our species or improve our planet in some way?

Are you serious? The very fact that Mars once had an atmosphere, once had [possibly flowing] water, was once possibly habitable, etc and yet now lacks those things means its precisely a very good potential model of what Earth may become in the distant future. Knowing this and specifically examining what is left on Mars may do very much to help us figure out either to cope with those risks or to even entirely avoid them realizing that Mars is a cautionary tale of what may happen if humanity does nothing--although odds are good, humanity won't be around by then. In short, we'd be able to learn from the history of Mars just like how we learn from our own history, to use as a guide of what has and could happen to decide on what to do to avoid bad things from happening again.

At the end of the day, for it to be worthwhile beyond the science that we are doing right this minute with rovers, there has to be something of value on Mars. Real, tangible value.

At the end of the day, the real question is what one places value on. Is it shiny trinkets and beads? Or is it one's life to enjoy those shiny trinkets and beads? And if one is forward thinking enough to recognize this, maybe one may be forward thinking enough to consider one's grand children or great grand children and just exactly what steps are necessary, in general, for the survival of humanity. But, you know, that all depends on if you see any value in humanity.

Materials that are rare on earth, a stopover for energy to reach other parts of the Solar System and beyond, a low gravity place to make materials that we can't produce on Earth, or even a "lifeboat" for humanity - at the end of the day there has to be something a step beyond just knowledge for the sake of knowledge.

Rare on Earth materials? Quite pointless except for a Mars colony itself. Stopover for energy for other pats of the Solar System and beyond? Not really sensical in any way since a free-floating platform would be actually maneuverable and would avoid almost all the escape velocity concerns. Low gravity for making materials? Uh...why not LEO and whatever gravity as needed through rotation instead of flying all the way to Mars and back? "Lifeboat" for humanity? Pretty well outside the scope of reasonable given the shear scope of reach to make Mar

To the skeptics of foundational research: Please take a look at the state of knowledge 300 years ago and try to find an example of genuine knowledge of that time that has no useful applications today. I don't claim it's impossible to find examples, but I'd submit that it's fairly hard.

Ann's belief system has two parts. One, rocks don't abuse people. We can dispense with that part. Two, if you don't study Mars before you terraform it, you lose any chance to learn about its past. We will change Mars just by being there. Since Mars has been so rocky for so long it has been simplified, and we should be able to get simpler answers to some of our questions. When we answer questions about geology we learn more things that we can use, because we live on top of geology.

This is why the second resource to be scouted on Mars for local consumption (after water) will be fissile material (probably Thorium so you don't need vast amounts of water and a pressure container).

Which also doesn't work, because that hasn't been true of Earth either which is far more terraformed than Mars will be for a long time. We still learn a lot about the past, both our pasts and the geological past of the planet itself.

Re:Crossing my fingers

[drinkypoo]

A lot of important clues will be lost if we introduce a bunch of new stuff into Mars' atmosphere. It's not that we won't learn anything, it's that we could learn so much more by studying it for a while first, taking some really good samples and so on, maybe even tenting over some sites for later study.

Re:Crossing my fingers

[khallow]

Or we could learn that now. It strikes me that people won't be impressed by that argument in a few centuries (when the actual capability to begin some sort of mass terraforming of Mars might be around) no matter how things turn out, unless someone looks for and finds something worth preserving by then.

Re:Crossing my fingers

Re:Crossing my fingers

[FatLittleMonkey]

I meant the total cost of the returned product vs its locally mined competitors. Platinum group metals extracted from asteroids may currently be much more expensive than Earth-mined PGMs, so there's no market for bringing asteroid-PGMs down to Earth. But to get anything from Earth into space adds thousands of dollars per kilogram, changing the cost equation dramatically. So the initial market for anything produced in space is to use it in space.

(Of course, once we have in-situ fuel, reusable cargo transport between asteroid mines and Earth-orbit, and are making enough profit to have paid off all our asteroid mining technology, then we may find that a "waste product" from our asteroid mining, like PGMs, or even nickel-iron, is price-competitive even on Earth. When we cross that line, the rules of the game change forever.)

The pre-conditions that made Mars what it is (low insolation, no magnetic field due to a massive impactor, low gravity, etc...) aren't anything humans can either cause or survive if (by magic in a couple of cases) they happened here.

Uh huh. And I never said anything about humans being a potential cause in the future. And the lessons of survival would be most useful in the generic sense, to understand how life evolved on a planet that--in geological terms--quickly lost its atmosphere and water and how life adapted to those conditions until the environment became, presumably, uninhabitable. As the saying goes, necessity is the mother of invention. It's quite possible we'd learn a lot of very interesting and useful biology and genetics from life on a very different planet that would be very pertinent to life on Earth.

Yea, that really presumes that humanity might actually be around in one form or another--along with enough cultural knowledge--in a few million years and no, it speaks nothing of Earth being remotely in the same state as Mars in that time. Off hand, though, I could imagine learning more about life adapting to adverse water shortages on a larger scale or to a radical change in atmospheric component concentrations or quantity would be rather useful for considerations of long-term space travel. Even if nothing of the sort is gained, just finding out the actual biology of life on another world would be potentially amazingly useful to better understanding life.

Though I guess it's handwaving feelgood to actually try to keep humanity around in the cosmos, in general. Perhaps it's not really meant to be in any real sense. But, we are so dwarfing in our knowledge to really know at all what can and should be, that it seems more handwaving cynicism to presume from out limited knowledge of today that we have some real idea on the possible when we're unwilling to even remotely seriously invest into the very tangibly doable of today.

Re:Crossing my fingers

I remember watching the old BBC show, 'Connections'

It was a fascinating take on history, but after a while I noted that almost every invention was first developed (at great cost) to aid some war effort (blow up stuff, target artillery, canned food for soldiers, refrigerated beef for soldiers...)

Even a vast amount of 'foundational' research that produced our beloved net-centric world was largely produced to provide decentralized communications following a nuclear war...

Re:Crossing my fingers

Some things are expensive because they are rare and/or pretty with few non-aesthetic uses (like gold.) Some things are expensive because they are rare and/or pretty with substantial non-aesthetic uses (like platinum). Massive amounts of gold would quickly lead to oversupply and lower prices, the demand for jewelry is reasonably small and the use in plating electrical contacts requires very small amounts. Massive amounts of platinum would allow several types of industrial uses on a large scale (it's a great catalyst and has uses in some battery tech) thereby increasing demand and potentially preventing a price crash.

Of course that all depends on how much "massive amounts" actually is, but with some things the cost drop will be offset by the increased demand for similar total profit.

Actually, I do kind of wonder if it is getting to the point where it would have been cheaper just to launch rad waste into space

No. That's the part that doesn't matter.

DeBeers & Diamonds?

It also occurs to me that even if the supply was significant, the difficulty in creating enough capacity for bringing it back in large quantities could keep prices high.

Metal madness

[FatLittleMonkey]

Differentiated metals on Mars almost certainly came from asteroid impacts. (*) So discovering rare elemental metals on Mars means that you'll find it on asteroids (ie, not just on metallic asteroids, impacts mean the average carbonaceous will have a good coating of metallic elements.)

(* Unless there's some native metal crapping lifeform on Mars. Which is also okay.)

Been reading Ender in Exile?

Cartoon?

[seandiggity]

Someone needs to animate the rover dropping a piece, driving a few yards away, turning around, dropping a piece, going to inspect the first piece it dropped...and on and on...until it falls apart. Maybe title it "Curiosity Killed the Curiosity".

...and somewhere in there is a metaphor for human endeavor :P

Certainly

[WindBourne]

You can do that on yours mar's rover.

No, not a beer can.

A huge Coca-Cola sign. It's what the Allies found as they captured island after island during WWII.

I wonder if the size will be limited to 24 oz.

Re:How about a better rover?

[macbeth66]

Seriously...

Was the damn thing built in China?

Guilty ones are sacked

[tokul]

Marsian who left it on rover's path is sacked. The one who made it look like rover's skin part is promoted. http://www.youtube.com/watch?v=ZYzM1M1X790

Knotted strings?

[aglider]

I'm fully aware I'm not a mechanical engineer, nor an expert of off world rovers.
But when I see all those strings hand-knotted to tie the rover's (unshielded) cable, I feel a chill on my neck!
Is that all the technology we could sport to have a reliable and durable rover?
It's just my ... curiosity!

Re:Knotted strings?

[DMUTPeregrine]

Cable lacing is a very good way to hold a wire harness together. It's more expensive than zip ties due to the labor needed, but less likely to damage the cables under stress. You don't see it very much these days since zip ties are cheap and good enough for static applications, but well-done lacing is used for high-end applications like the rovers.

I hope they find something that justifies a manned trip.

Women

Extra points if they are green and have 3 breasts......and not in binders.

Proof! Rover was designed by Apple!

[TheSkepticalOptimist]

NASA will issue an apology letter "well metal scratches and plastic flakes off, just like our competitors".

But seriously, I know I can go to the beach with my niece and nephew and dig holes with $1 plastic dollar store shoves and not leave bits of it behind.

PhD PHB?

[Tablizer]

NASA is just like my boss: ignore the primary mission and instead chase after shiny GUI's and elusive sparkling rumors.

Re:My keys

[Tablizer]

So that's where all the missing keys, TV remotes, 80's p0rn stash, and left socks go. The greatest scientific discovery ever!

That's one small scrap of plastic...

for a rover, one giant bag of garbage for humankind. (dabs eye)
