Ion engine breakthrough
French scientists have developed a prototype of the first wall-less Hall type thruster. This ion thruster requires 100 million times less fuel than the type currently in use. However, despite the operative life of the engine having been significantly increased to withstand a deep space mission, it still needs further improvement for a safe mars trip.

Great video about developing technologies
Neil deGrasse Tyson shows you some problems between us and mars, and some promising future solutions. We'll see space food, spacecraft protection and new, more mobile pressurized space suits.
