NASA Successfully Tests 'Impossible' Propulsion Device

One of biggest things holding humans back from taking the next big leap in space exploration, is propulsion, or lack of it, actually. While advances have been made in the engines that power our satellites and space probes (like those that delivered the Mars rovers), our spacecrafts' mass are typically made up of at least 50% of their fuel payload. Our ships have to carry a huge amount of fuel around with them in order to get where they're going. Well, that might not always be the case, based on some new research carried out by NASA.
