Rocket science – how hard can it be? [video]
- TeMPOraL 12y agoNot hard at all. Here are few key points to remember: - parachutes go at the top, engines goes at the bottom - engines point down - don't mess up your staging - if you didn't go high enough, put more boosters - if you fell apart in flight, put more struts Sincerely, Jebediah Kerman.
- gizmo686 12y agoJebediah is an accomplished pilot, but does not know much about building rockets. I am sure that Bill Kerman would have a few choice words to say on the subject.
- TrainedMonkey 12y agoGiven amount of rockets of all types of quality that Jeb had been in, I think he developed quite a intuition for how a good rocket should be built. In particular this is not it: https://www.youtube.com/watch?v=R0JUMFXlOsU https://www.youtube.com/watch?v=R0JUMFXlOsU (No wonder Jeb did not pilot this one).
- munchbunny 12y agoJebediah does own a vendor company that works with the space agency, so one can only assume that he is essentially Elon Musk but greener, and also an astronaut.
- delibes 12y agoThis guy is very entertaining in the video, and what they're doing is very practical. Rocket engines sometimes get described as extreme plumbing. Big rockets that are more powerful than the simple solid rockets the video describes tend to use cryogenics like liquid oxygen (-185C/-300F) in one part of the rocket, and then at the other extreme have a combustion chamber over 1500C/2750F that will melt most metals. Rocket science is hard. For some more good reading, there's a great usenet archive of sci.space at http://yarchive.net/space/index.html http://yarchive.net/space/index.html
