  1. Re:KISS on NASA's Shuttle Plans · · Score: 1

    That's just the problem - it isn't. There is nothing significant from SS1/SS2 that can be evolved into an orbital craft.

    You're looking at the project from the wrong perspective. SS1 was never designed for anything but sub orbital joyriding, hybrid motors dont have anywhere near the Isp to reach orbit.

    You should instead consider White Knight to be a 'test platform' for a much, much larger dual tailplaned carrier aircraft, this makes the whole project look a lot more interesting. To me, it sounds like a real neat way to marginally increase your launch vehicle's efficiency, and at the same time cut your range fees and third party liability to practically nil.

    The ISS is in the wrong inclination. It's too difficult to get any mass to if you're not launching from kazakhstan. That, and it's boondoggled to the shuttle.

    And now that the X-Prize MIGHT result in commercial orbitals, how much harder is it to go the moon once you are up there?

    Not much harder. Once you're outside of the atmosphere you dont need to worry about using massively high thrust chemical rockets to get you up quickly, or dumping ludicrous amounts of energy on reentry.

    You could pretty much just strap a low weight inflatible habitat like the ones Rob Bigelow is building to an apollo era LEM and a cheap pressure fed rocket.

    While I'm not going to say that the use of the atomic bomb was immoral It was immoral. They should have been demonstrated on a landmark like Mount Fuji or on a military base, not in the middle of a city against civilians.

  8. Re:Lehr is right on 60th Anniversary of the Atomic Bomb · · Score: 1

    At the height of the cold war the Soviets tested 'The Czar', with a TNT equivalent of 10 times everything used in WWII, Hiroshima and Nagasaki included.

    They were predicting 100MT at full yield. Half of that was to come from fission, which would have released more fallout than every atmospheric test performed in the 1950's combined.

  10. Re:So much for stopping nuclear proliferation. on 60th Anniversary of the Atomic Bomb · · Score: 2, Informative

    Well, the USSR's Tsar Bomba has the biggest yield of all bombs. At 27 tons though, it was damn hard to deliver. Anything large enough to carry it would be easily shot down well before it made the target. The deadliest is probably the Trident II. It has eight compact half megaton warheads and decent range.

  13. Re:Understanding Evangelion [POSSIBLE SPOILERS] on Cartoon Network Acquires Neon Genesis Evangelon · · Score: 1

    It's no wonder CN changes Anime. That description sounds godawful. I was mildly curious about what this show was until I heard it was the apocolypse told through robot-piloting teenagers. I've watched my fair share of cartoon's as an adult, but calling that plot "entertainment" would be a stretch. Yes, they spend half a million on licensing and translating the show, and then some accountant tells them that they need to cut costs, and cant splurge a few hundred quid on hiring a decent copywriter to sell it.

  14. Re:a rocket? on Next NASA Vehicles To Resemble Shuttles · · Score: 1


    Nuclear propulsion is ready as soon as society says it is acceptable. Project Orion in the 1960's developed it, and was cancelled. There exist designs (indeed; Pratt and Whitney is ready to make a tri-mode nuclear engine called the Triton with Isp ranging from 300-900).


    I prefer the uranium tetra-bromide salt water method myself, although there is absolutely ZERO chance that anyone will allow it to be used for LEO boost stage. For a start, it's probably a violation of the 1968 test ban treaty.

    You pump a roughly 90%+ enriched uranium fuel mix from nice neutron absorbing boron-carbonate capilliaries into a detonation chamber, and allow it to go critical. Basically a liquified fission bomb with an Isp of about 10000s.

    Consider a better, safer, cheaper and much faster way to get from NYC to Tokoyo with near-future tech: A maglev train via an underground tunnel, in vacuum for frictionless acceleration to ludicrious-speed at the midway point before decel. It doesnt have to be underground, you could bridge the Bering, Mamiya and La Perouse Strait's.

    The government will use bloggers' desire to be taken seriously as real journalists as an excuse to apply the same kind of censorship the FCC effectively has doled out for some time to the traditional media.

  19. Re:Oh, puh-lease. on Nanotech Protests Begin · · Score: 1

    Consider a city. Looking down from a satellite, choose a random car in the city, and try to predict its movements. Not very easy. But predict the movements of the cars in the city as a whole, as people arrive from suburbs in the morning and return to them at night? Much easier.

    Consider the state of a city recorded 50 years ago. Using that dataset, try to predict the future movements of cars in the city using your fancy algoritm over the next 5 decades.

    Now, compare the results you achieved through the algorithm with last years traffic. Did the results match?
