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.
- New Zealand-based Rocket Lab has a partially 3D-printed rocket engine scheduled to launch later this year. Its Electron rocket powered by 9 Rutherford rocket engines can get small satellites into orbit — for just $5 million (versus a $60 million SpaceX rocket or even more expensive competitors). [url]
- NASA has successfully tested several components of a 3D-printed rocket engine, and it’s well on the way to making an entire rocket engine from 3D printed parts. Nearly every rocket maker is using 3D printed parts — SpaceX uses additive manufacturing for its Merlin rocket engines, and more traditional aerospace giants are no strangers to 3D printing. [url]
- The Portland State Aerospace Society (PSAS) is a student organization that has already launched an amateur rocket 3 miles high. We’ve mentioned other student rocket projects before (USC reached an altitude of 4 miles a while ago), and the Civilian Space eXploration Team (CSXT) made it to 72 miles up in 2004. [url]

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.
Re: Rocket science is hard?
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.
Re: Re: Rocket science is hard?
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. 🙂
Re: Re: Re: Rocket science is hard?
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.
