Heinlein and Sir Arthur C. Clarke. And for planting the seed, Jerry Pournelle and his "A Step Farther Out: Those Pesky Belters and Their Torchships" EST^D 1994 A Rocket is Just The Thing! * [AtomicRocketLogo256] * [AtomicRocketSeal256] Click the bar labeled SITE MENU at the top of the screen to navigate the website --------------------------------------------------------------------- Your imagination has been captured by the roaring rockets from Heinlein's SPACE CADET or the Polaris from TOM CORBETT, SPACE CADET. But are such rockets possible? How does one go about defining the performance of these atomic-powered cruisers? This document gives some hints and equations that will allow back-of-the-envelope calculations on such matters. Though horribly simplistic, they are far better than just making up your figures. This site was mainly intended for science fiction authors who wanted a little scientific accuracy so they can write SF "the way God and Heinlein intended" (Arlan Andrews's Law). The technical term is Hard Science Fiction. 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, high school mathematics, 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. The engine and the torchship pages explain how easily do some of the calculations using Nomograms. The nomograms can be downloaded from those pages, or printed versions can be purchased from the Project Rho Store. There is also a poster of the Atomic Rocket Cruiser Polaris. Not to mention official Atomic Rockets coffee mugs and blank journals. While this site originally focused on rocketry equations, as you can see it has grown to encompass other topics of interest to science fiction authors and game designers. Things like galactic empires and interstellar trade. This site started out as a small sheet of equations I wrote in 1997. You may find it amusing, abet very dated. --------------------------------------------------------------------- Start here --------------------------------------------------------------------- Patreon * [patreonSplash] Alas, updates to this website are very sporadic and far in between. I've got about a five year backlog of data that is yet to be incorporated. You can help by becoming my patron on Patreon. For just a few dollars a month you can help break the log jam and allow me to get this website polished and tuned. Patreon is sort of like a cross between Kickstarter and medieval artist's patrons.

The author crafted the mesh using blueprints of the Polaris from the Spaceship Handbook. The NERVA solid-core nuclear thermal rocket was created using reference images of NASA mock-ups. The green equations are from other pages in this website. The background image of Earth is courtesy of NASA. There is a larger version of the image here. For dramatic effect I made the exhaust a blaze of blue. In reality, a hot hydrogen blast is invisible.
