So please help me out here. The article suggests a craft could be accelerated to .3c; surely this would not be for a Mars intercept!?<p>This is just an example of the potential, right? Otherwise slowing down a craft at relativistic speeds for Mars capture sounds... difficult to say the least.<p>EDIT: OK, after thinking it through further at .3c the trip would only take about 50 minutes, roughly. So clearly that&#x27;s not what the article meant.
