Two-burn Maneuver Will Get Us to Mars Twice as Fast September 30, 2009

Posted by showmescifi in scifi.

Interesting article on Wired today about an old SciFi idea that is new to Nasa.

The idea dates to 1929 and is called the two-burn maneuver. It basically relies on the premise that a faster moving object has more energy than a slower moving object.

So, if I was  in a spaceship at a space station i near the moon, I’d first have to rocked back towards the Earth. Then I’d point the ship toward mars and get a gravity assist and punch the rockets again.

Gravity assist is a common NASA technique but combining it with additional thrust is something that isn’t common.
