Question Going to Alpha Centauri

I write Christian Science Fiction. I try to make it almost 100% do-able. 150 people are going to Alpha Centauri. The trip will take about 40 years, so they are traveling 10% light speed. I don't know how to get them going that fast. I have them getting up to speed by focusing atomic blasts for about 30 days then switching over to multiple ion drives. the whole system is nuclear powered like a submarine. Is this possible ? What woudl be more realistic ? I have them going inside a hollowed out asteroid for rasdiation and meteor protection... Would it weight too much ? A better idea ?

Re: Going to Alpha Centauri

Hi Alpha,

The idea of using nuclear explosions to propel spacecraft has been around for some time, Project Orion was a real life study done on the feasibility of such a feat.

You may also want to check out the spaceship design forum for 'The Prophesy' a fictional space ship that takes a voyage to Jupiter (at present) and is propelled by continuous micro-nuclear explosions.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.
