Solar-Powered Moon Rover To Explore Apollo Landing 151

Mike writes "Carnegie Mellon roboticist Dr. William Whittaker has teamed up with Astrobiotic Technology to develop a solar powered moon rover that will explore the Apollo landing site in 2011. The photovoltaic clad robot features two electric motors in the hub of each wheel, and a half cone of solar generators up top that will power the wheels, run computers, and beam stereo HD video back to earth. The project has been entered in the $25 million Google Lunar X Prize competition."

      Why? Sure, its "cool" to preserve everything, but its a heck of a lot more valuable to see how the machines have fared for the eventual colonization of the moon and for future generations. I'm not exactly sure what the point is if we are looking back on history rather than creating it.
      • Mod parent up. Why should we preserve it? How are we suppose to move forward (by seeing how the machines have fared and see if it is possible to use this as a launch to Mars or possible location for colonisation) if we refuse to tread on the steps of those that came before? Simply keeping the markings there for no other reason then posterity just sounds like a waste to me when there are things we can learn.

      Do regular international salvage laws apply to abandoned moon gear?
      • I would think that no laws apply in space. Sure, we have the moon treaty, but that's hardly a paninternational agreement.

        The only rules that apply are those that others have the ability and will to enforce. Both factors severely reduce the number of people that will bother you up there.

      Because the relics of the past visits will give us valuable insight into long-term exposure of our machinery in the environment of the Moon - something that is surely relevant to future efforts of colonization. All the things we left behind have been sitting (hopefully?) untouched for 40 years getting bombarded with micrometeoroids, experiencing huge temperature swings and moonquakes, and generally experiencing the reality of existing there.

      I find it fascinating and am excited to see pictures of how the sites have weathered.

    Moonquakes [nasa.gov] are pretty damn cool from a seismological perspective. Beyond that, some of the ones recorded by Apollo-installed seismometers were >Mw 5. Big enough to be damaging.

    The moon isn't tectonically active, of course, but it is seismically active, and the data recorded in the 70's indicates that the moon's lithosphere is a very different beast compared to earth's. At any rate, it would produce some extremely neat data!

    First off, it's bullshit. They may develop the thing, but it's not going to fly itself. The Google X-Prize money is for the development, not the flying, and it's not enough to get it there anyway.

    They WANT to have it explore the moon (actually they want to be seen wanting to do so, in order to increase their chances of getting the prize money; you think the timing of the announcement was random?). There's nothing here about anyone else wanting them to.

    And given their announced target, I think they've just pointed the space demodulator at their foot. Far too many people would be offended.

    All in all, this is a PR job. The guy may be capable of developing, but the chances are that having teamed up with this company, their plans are to get the prize money, maybe develop, maybe not, and know for certain ahead of time it'll never leave the ground. They just want the money. The tip off? Such a device could do valuable research, such as roving around the south pole looking for ice. Are they planning any useful or noble venture like that? No. They're planning on some virtual tourism, and true to big ticket money tourist ideals think that they're permitted to walk on anyone's lawn they wish just so they can take their holiday photos.

      I'm not sure about this. Kicked up lunar dust particles move in parabolic trajectories. Since there's no atmosphere, they won't stay afloat and disperse. So, if you know which way the wheels will kick up dust, you can strategically place the solar panels where they won't get dusty. They'll stay clean forever...

      That bit about the batteries is really ridiculous. A thin aluminum foil will protect the batteries from thermal radiation just fine. Apart from that, there's no "temperature" on the moon...
