article_snippet: So one scientist took a look at different types of propulsion - including nuclear - to find out if there was a quicker way to get there.
article_snippet: their looked at four different kinds of propulsion - chemical, ion, nuclear and a concept electromagnetic engine.
article_snippet: CECE is a type of chemical propulsion, Nerva is nuclear propulsion, RIT-XT is ion (electric) propulsion and PEMT is Pure Electro-Magnetic Thrust .
article_snippet: One of the proposals for nuclear propulsion is that a reactor could emit particles onto a giant sail, which would propel the craft forwards.
article_snippet: This is similar to a solar sail
article_snippet: I think for this particular case, nuclear propulsion will be the best option.
