    I think you might finally have found an application for orion technology. However, not to do a kinetic impact, or send up a demolition team. Use the orion to push the asteroid into a usable orbit.

    The dinosaurs became extinct because they didn't have a space program.

    How do we know the dinosaurs didn't have a space program? Obviously the ones who remained behind became extinct, but the ones who took to the stars would still be en route to Proxima, would they not?

  4. Re:60 Minutes on Flying Cars Ready To Take Off · · Score: 1

    Because the topic blurb specifically states that a test pilot demonstrated the craft for 60 Minutes, so someone saying that they saw it on 60 Minutes *is* a little redundant.

  5. What always bothers me... on 35th Anniversary of Apollo 13 Splashdown · · Score: 1

    When the shuttle first flew, there was a concern about the tiles. I remember stories about how they flew the shuttle over a telescope in Hawaii to check the tiles. I also remember talk about a device that would squirt an ablative goo into the cavity of any missing tile. Lately, I hear that there's no way to repair tile damage in orbit. What ever happened to this device?

    Fairy cake is for extrapolating the entirety of the universe, and then for eating, if you survive the Total Perspective Vortex and are still feeling a little peckish.

  8. Re:Poor Comcast on Comcast Sued For Giving Customer Info to RIAA · · Score: 1, Insightful

    The company, Settlement Support Center, based in Washington state, was using information that the Recording Industry of Association of America had obtained in a Philadelphia lawsuit over the illegal sharing of digital music files

    The RIAA obtainded the info in a lawsuit. Legal authorities were therefore involved, and Comcast was thus well within the Terms of Service releasing the information.

  9. Re:Poor Comcast on Comcast Sued For Giving Customer Info to RIAA · · Score: 4, Informative

    You expressly authorize Comcast and its suppliers to cooperate with (i) law enforcement authorities in the investigation of suspected legal violations, and (ii) and system administrators at other Internet service providers or other network or computing facilities in order to enforce this Policy. This cooperation may include Comcast providing available personally identifiable information about you to law enforcement or system administrators, including, but not limited to, username, subscriber name, and other account information.

    Sounds like the subscriber doesn't have a chance, once the copyright cops get involved.

    I seriously doubt that. It wouldn't take much thrust to do a mid-course adjustment of the craft to allow a polar orbit vs an equatorial orbit.

    Sorry, I guess I wasn't clear. I know NASA does neutral buoyancy spacewalk training, but I don't think that they do the 1/6 gravity lunar excursion training anymore.

  15. Re:Strip Mining the Moon? on Site for Moon Base Determined · · Score: 1

    I say that instead of mining the moon, that we capture a comet, wrap it in a giant plastic bag and use that for fuel. Solar power could melt the comet. Directing the outgassing can put the comet into a much better orbit.

    Even if it is constantly illuminated as a whole, it is still lit on one side, and dark on the other. Any solar collector would have to have a rotating reflector to work.

  22. Re:Dammit, skip the moon, go to Mars... on Site for Moon Base Determined · · Score: 1

    Stopping at the Moon on a trip to Mars definitely doesn't make sense. However, there is a logic to using the Moon as a place for dress rehearsal and training. It's only days away, rather than months.

  24. Re:Lets clear up some Gravity and Leaping issues h on Site for Moon Base Determined · · Score: 2, Informative

    I'm not sure where you're getting your equations, but clearly the man will be able to jump six times as high on the moon as on the earth, and three times as high on Mars.

    When you jump, you provide kinetic energy to your body. As you rise, the kinetic energy gets transformed to potential energy. At the top of your jump, all the kinetic energy has been converted to potential energy and you come to a stop. The potential energy then gets reconverted to kinetic energy as you fall. The potenial energy is determined by the equation u=mgh, where u is energy, m is mass of jumper, g is the gravitational force, and h is height. Or rearranged, the equation would be h=u/(mg), or height is inversely proportional to gravity.

    So, assuming the mass of the jumper and the energy put into the jump remains the same, the jump on the moon would be six times the height as on the earth.

  25. Re:Hello Slashdot reader, I am Ignignot & this on Site for Moon Base Determined · · Score: 1

    NASA astronauts train underwater because their buoyancy can be adjusted to completely counteract their the force of gravity. Effectively, they are "weightless". It has nothing to do with 1/6 gravity of the lunar environment. Training for that is done in a counterbalaced harness much like the flying wires used by actors (Beyond Thunderdome) or a child's Jolly Jumper. NASA probably hasn't done any of that sort of training for thirty years, or more.
