DailyDirt: Cheaper Rockets Taking Off

from the urls-we-dig-up dept

Rocket science is difficult, but as technology gets better, it looks like more and more people are capable of launching pretty powerful rockets. Private companies are semi-routinely shooting satellites into space, and that capability could be useful for all kinds of applications ranging from scientific exploration... to intercontinental missiles. If hobbyist drones seem like a problem now, wait until more hobbyist rockets are launching into space. After you've finished checking out those links, take a look at our Daily Deals for cool gadgets and other awesome stuff.

    Who will be the first to sell a cheap rocket to North Korea?

    Also, SpaceX's SuperDraco engine is completely 3D printed.

    Just sayin'.

    Rocket science is hard?

    Horse puckey. Rocket science is trivial. Here: F = d(mv)/dt
    That's it.

    Rocket engineering is pretty damned hard, not the science.

      Try adding the change in vehicle thrust and weight components to your calculations. Agreed, it is more math then science but your simple equation hardly addresses the real world parameters that need to be accounted for.

        I think that's his point: there's a difference between science and engineering, and "rocket science" as commonly used is incorrect.

        I love a good bit of pedantry. :)

          Agreed.

          Also, there is a bit of science required in order to predict the change in air density with altitude and its impact upon friction. Also required is an understanding of the corrosive affects of atomic oxygen and how to mitigate it.

    And NASA is now saying that it will cost billions to develop a domestic rocket engine to replace the Russian-built RD-180, which somehow became a critical mainstay of the US military and space program.
