Rocket Science (Sort Of)

The site is called Atomic Rockets. In the webmaster's own words:

This site was mainly intended for science fiction authors who wanted a little scientific accuracy. But anybody who is interested can play with the toys contained within, designing their own Planet Rangers Rocketships. It is assumed that the reader has enough knowledge to know the difference between a star and a planet, and enough skill to use a pocket calculator. Computer spreadsheet and computer programming skills are a plus, spreadsheets in particular will make your life much easier.

This guy has made a fascinating site that covers such topics as Atomic Rockets, believable aliens, anti-gravity, life support, sidarms ... He has 30 pages of material and it is probalby growing. In the Preliminary Notes, he does make the following disclaimer: I am not a rocket scientist, merely an amateur that has read a lot of books. Any and all of the information on these pages may be incorrect or inaccurate. And he has read quite a few books. And all of that reading has fueled his research, of which he must have done quite a bit. His site is filled with great tips, relevant links, and cool illustrations. http://www.projectrho.com/rocket/index.html
