    • this seems to be the thing we need to fix our ENGINEERS arithmetic vagaries.
    • When contacted to determine the achievable velocity of the balls, NASA engineers could only describe their speed as "Ludicrous".

      • Considering the Density of the martian atmosphere, those things are going to have to be very big, and very light.

        If I recall correctly, the atmosphere of mars is one percent of that of earth. Which basically means that for the wind to have as much effect on you as a one mile an hour breeze, it has to be going one hundred miles an hour.

        An example of this is the effect on dust in the atmosphere. The normal winds are simply not adequate to raise dust in any way. So the question then is, where do the famous martian dust storms come from? The answer seems to be meteor impacts, which would throw up enough junk into the atmosphere that it could take a while to clear out and settle down.

        And so the red surface of the face of Mars makes more sense, when you imagine the impact of iron dust from the core thrown up and attracting all the free O2 in the atmosphere.

          The pressure of wind is proportional to the square of the windspeed relative to whatever its hitting. Martian winds are faster than on Earth. This thing doesn't have to be light either. Changes in the weight would affect acceleration, but have little impact on the top speed.

    NASA builds this huge ball that can roll over anything. Packs it with cameras and sensors. Launches the thing from way behind the three point line, and gets it to Mars. Only then do they realize the ball is opaque!
  • Once upon a time warp. . . .

    In a galaxy very, very, very, very, far away, there lived a ruthless race of beings known as . . . Spaceballs.

    The evil leaders of Planet Spaceball, having foolishly squandered their precious atmosphere, have devised a secret plan to take every breath of air away from their peace-loving neighbor, Planet Druidia.

    "I see your schwartz is as big as mine!"
  • Wouldn't a balloon be better for this? Rather than inflate a big ball around the equipment, just attacth a balloon and inflate it when you need to move to another location.

    • That was my first thought. It would be more mobile that way.

      • Nice idea in theory, but Mars' atmosphere is much thinner than Earth's. One would need a damn big balloon to lift a payload of any practical size. Researchers working on airplanes for use on Mars have similiar problems.
        • On Earth, the Helios solar-powered plane reached nearly 100,000 feet. A manned balloon has reached 121,000 feet, and unmanned balloons have undoubtedly gone considerably higher without the weight of life support gear for a crew. Atmospheric pressures at these altitudes are comparable to the pressure at Mars datum altitude. You've also got to remember that payloads way only about 1/3 as much on Mars, considerably reducing the lift required.

          So, yes, it's a considerable challenge to fly a balloon, let alone a plane, in the Martian atmosphere, but it's not impossible.

          • Have you seen the size of this Helios thing? It would have to fit into something that could survive the trip into space and entering the Martian atmosphere. Not to mention that Helios looks extreamly fragile. I'm sure the upper winds here on earth and mighty rough, but Mars is a planet that has year round hurricanes the size of which we would never see here on earth.
    • The ball has some advantages when compared to a balloon:

      The payload can be much larger, as there is no need to actually make it fly.

      Control of the balloon is probably much harder.

  • Well, Martian lovers everywhere will now have new evidence to point to when it comes to "life on Mars" ... Roads wide enough to accomodate a small house, are subtly but surely impressed all over the planet's surface.

    Or, if there really was anything to learn from the arrangement of the planet's surface, we'd be compromising the integrity of the research by plowing it all over (however gently we may do it with this massive lightweight ball)

    I always thought it would be kind of sad if one of the celestial bodies we explored actually HAD intelligent life, and we kept on sending satelites over it and robotic probes over the surface.

    A few Pathfinders are one thing, but can you imagine if an alien ship came above New York City, dropped house-sized balls and had them "blow around in the wind"? Say there is a living creature on one of these planets that is small enough to be crushed by one of these things, but measurably intelligent? The balls seem like overkill.


  • I keep waiting for NASA to come up with a technology that is cheap, automated and can be deployed in vast numbers.

    To oversimplify the issue: drop a few dozen/hundred/whatever floaty, bouncy balls all over Mars and kick back and let the data roll in. Sure some of the balls will be lost, but as long as a few do their job the mission will succeed.

    Sure there are weight issues getting all these things over there, but if the probes were simple enough their and ther numbers large enough I'd imagine that they'd be more successful than other probes have been.

      That is something I would like to see. Rapid exploration of large parts of the Martian surface, and not only a few small pathces here and there every two years. Currently we are stuck with the latter.

      Cheap and vast numbers are equivalent. I think the costs of any new space equipment is mainly research and development. After it is done, you can make dozens of units with a price that is small when compared to the initial costs.

      Launch costs are still the biggest problem of space operations, and this has nothing to do with that.

  • Ok, I'm Mr. Joe schmoe here who is relatively unimpressed with NASA. It seems like we've hit a dead end or perhaps rather slowed down to a snails pace when it comes to space and planetary exploration. Why aren't we concentrating on simply getting a large payload up into space? Perhaps if payload wasn't such a large factor, we wouldn't have to depend on inventions like "Spaceballs." Isn't it something like $10000 a pound for space shuttle cargo? Utterly rediculous IMHO.

    • Maybe it would be more practical in the long run to just work on a way to produce what we need in space, instead of hauling everything up.

    • Why aren't we concentrating on simply getting a large payload up into space? Isn't it something like $10000 a pound for space shuttle cargo? Utterly rediculous IMHO.

      The 'better, faster, cheaper' has concentrated too much on the 'cheaper', or 'what programs will be (ex?)terminated', mainly as all these budget cuts have forced them to. 'Faster', or 'get before the next budget cut) is also stressed a lot, but I think they have not concentrated on 'better', expect in the 'pretty pictures' field. However, I have not seen a radical restructuring that would be a consequence of a new choice on priorities. I feel NASA has lost the initiative and is mainly reacting to outside political pressure.

      Considering that the Shuttle is almost 20 years old, USA should have something better. The research on better launchers is extremely expensive, and it will not produce nice pictures that are important to the average politician (and voter). Given all the NASA budget cuts we keep on hearing we will not likely see any significant improvement in American launchers for a long time. I think NASA is also more interested in doing something with the present launchers. If NASA uses all it's money on launcher development, they might notice their budget has been cut to zero when they have the cheaper launchers.

      I have heard that the Russians are seriously considering reviving the Buran program. (For the uninformed, Buran is the Russian Space Shuttle that has been tested succesfully in the Soviet times. It has been even in orbit. Now, it is mothballed somewhere in Siberia. One model is in a park in Moscow) Buran has some improvements when compared to the Shuttle, most important ones being: reusable launcher strap-on boosters and full remote control (a crew can be on board, but it can also fly unmanned). It has also plenty of smaller improvements, which make it easier to maintain.

      Currently, Buran payload is only slightly larger than what Shuttle can manage, but the Russians claim that with minor modifications, they could almost double the payload. If they revive Buran, it has a payload price less than half of what Shuttle has.

      If Buran is revived, I hope some people in Washington will notice that a few years ago USA had a 15-year advantage in the launcher race, but has lost it already. The Europeans have Ariane V (which is still getting improved), Russians will probably have Buran soon, and USA is still stuck with the old Shuttle. Now we all three are even, but in a few decades USA will be holding the 2nd or 3rd position.

  • Why are we so worried about Mars when we have a moon here we could be colonizing. That might help a wee bit in both Mars missions and general space observations. Kind of a jumping off point. We more or less have the technology (if 1969 put us there for a visit). NASA should take the tagline from another four letter company and "Just Do It"
    • I am also a member of the 'Moon 1st' crowd. We have most of the tehcnology and money, and some recent missions (Clementine, Lunar Prospector) have given us plenty of new information. ESA's new mission SMART-1 [esa.int] will be the next step (launch in October 2002), mapping most of the Moon in several wavelengths from IR to X-rays, with a resolution of down to 50 meters in the optical. It will give us a map on the distribution of the Lunar resources.

      In a few years we will be able to select the optimum place for the first Lunar base. After that, we should send a few robotic landers to study the places in more detail. And after that, we should get a base over there. I think it would take less than one decade to get the base there. Perhaps we should start lobbying the politicians, as otherwise they will do nothing.
