New Mars Discoveries 109

sighted writes "The fleet of five active spacecraft examining Mars (in addition to the recently-missing Mars Global Surveyor) have been working overtime. On the heels of last week's finding of possible flows of liquid water, the ESA has announced that an entire hidden landscape exists just beneath the surface of the Red Planet, and NASA has released some really amazing images of layered topography that will yield many clues to the history of this strange world."

        The Space Race is the race to get self-sustaining human habitations (whether something akin to L5 colonies, terraformed planets or moons, or whatever) in space before civilization collapses down here (from either internal or external forces) to the point where we'll never be able to try it again.

        Nobody has won it. Currently we're not even close, and we may even be losing ground.

          You do realize that it's corporations (Boeing, Lockheed, Orbital, etc) who do the bulk of spacecraft design, development, and operation in the US, right? And, for most rockets (obvious exception, the shuttle, which really should have been treated as a research platform, not a workhorse), these corporations have the normal profit motive, as they bear operating costs and compete for launch constracts. Often only the design is subsidized. Sometimes, as in the case of the Pegasus, even the design isn't subsidized.

          It's funny, people viewing corporations as the answer to high launch costs, when it's corporations that currently run the show.

          If what people actually mean is "smaller startups", they should read about the staggering non-success smaller startups have historically had with rocketry.

          That doesn't mean that the business world won't give us "the way forward". SeaLaunch hasn't done half-bad, and I keep an eager eye toward the progress of SpaceX's Falcon. But this isn't "something new". It's just the latest iteration of a long, ongoing process.

          This isn't really true. Most public corporations do have to maximize profits for their shareholders but in the case of a corporation with only one shareholder they can do what ever they want. When Ford got sued for not maximizing profits Henry Ford bought back all the stock and could do whatever he wanted.
          Also if a corporation is founded with the goal of not maximizing profits and makes it clear to prospective stockholders, it would also be legal though they might not be able to sell much stock.

        yep, because the best way to bring down the cost of space exploration is by keeping the corporations out. Corporate greed, together with competition, is the only way to bring down the costs of space exploration, like it or not. Today the corporations run the show, although not directly, but by getting polititians to do their bidding. Competition is non existent in todays government spending.

    The idea that the northern hemisphere craters were simply buried is actually a fairly old idea, even though the article makes this sound like a major breakthrough. We've had some radar images suggesting this for some time, I guess it's just now they're starting to get some press. The layered deposits are also well documented, but I do have to admit those are the prettiest pictures I've ever seen of them.
    • It's a fairly old _idea_, but there have been all kinds of ideas. I follow the Mars news fairly closely, not super-closely, and this is the first time I've seen what amounts to proof of buried craters. That's why people are excited, I think. Not because nobody ever had the idea before.

      Likewise with the layered deposits. Yes, those have been found before, but they were on a much smaller scale. These vast, flat, deposits really suggest ocean sedimentation over millions of years. (Suggest. Far from pro

      "spacecraft and robotic devices and test instruments do not have a workday, and are not limited by human weaknesses like the need for sleep, food, and bowel movements."

      Not quite true. They need to eat, sleep and shit - just not in the "biological" fashion that we carbon based life-forms do.

      It is well known that;
      A.) The Mars rovers are often limited in the amount of work they can perform due to light availability (food).
      B.) The rovers must also transmit data back to the earth (shit).
      C.) When power is limited due to lack of light, they must cease all science operations (sleep).

      I would say that both of these rovers do in fact have a workday, and that it is much harder than most of the folks here on Earth would care to imagine...

      • How does transmission of data equate to taking a dump? Unless you use Morse code to talk to people in adjacent toilet cubicles.

    Neat - It makes me wonder how it could have been covered up so well. Letting my imagination run wild... what if Olympus Mons let loose a cataclysmic eruption so powerful that it:

    1) put enough sediment into the atmosphere to cover the entire surface,
    2) put larger rocks into orbit which eventually decayed and came back down to form the rock-strewn surface we are accustomed to seeing, possibly forming some of the ounger crater impact sites, and
    3) blocked out sunlight, killing off any shred of life on the planet at the time of the event

    "How" this could come to pass is the first thing that pops into my mind - no speculation in the article though which I always enjoy hearing from NASA.

      1 and 3 are possible but I suspect 2 is unlikely , since to shoot out a rock large enough to cause the craters of the size discussed here would not only required far more energy than any volcano could ever produce but if somehow it did it would almost certainly completely destroy the volcano in the process. Its one thing to fire off rocks a few tens of metres in diameter , quite another to fire off mile wide lumps at sub orbital speeds.

    Scientific American is running an article about how it now looks almost certain that there were large standing bodies of water on Mars in its early history. However it goes on to say that this probably only lasted for a billion years or so before the water froze/evaporated and mars slowly turned into the dusty desert we know today.

    My own belief is that Mars slowly lost its atmosphere due to its low gravity and poor magnetic field and as the air pressure went down it was easier and easier for water to evaporate until at some point the pressure got to the point where the boiling point of water had dropped to below the ambient temperature of the planet and that was the end of the lakes/seas if there were any still around by then. Once in the atmosphere the water was dissociated into hydrogen and oxygen, the H2 escaped and the O2 reacted with whatever was around producing the rusty landscape we see today.

    No one would have believed in the last years of the twentieth century that this world was being watched keenly and closely by intelligences greater than man's and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinised and studied, perhaps almost as narrowly as a man with a microscope might scrutinise the transient creatures that swarm and multiply in a drop of water. With infinite complacency men went to and fro over this globe about their little affairs, serene in their assurance of their empire over matter. It is possible that the infusoria under the microscope do the same. No one gave a thought to the older worlds of space as sources of martian danger, or thought of them only to dismiss the idea of life upon them as impossible or improbable. It is curious to recall some of the mental habits of those departed days. At most martian men fancied there might be other men upon Earth, perhaps inferior to themselves and ready to welcome a missionary enterprise. Yet across the gulf of space, minds that are to our minds as ours are to those of the beasts that perish, intellects vast and cool and unsympathetic, regarded this planet with envious eyes, and slowly and surely drew their plans against us.
