New Engine Raises Possibility of Cheap Travel To the Moon
shreshtha writes with this intriguing bit from The Daily Mail: "A tiny satellite thruster which can journey to the Moon on just a tenth of a litre of fuel could usher in a new low-cost space age, its creators hope. The mini-motor weights just a few hundred grams and runs on an ionic chemical compound, using electricity to expel ions and generate thrust. The tiny motor isn't built to blast satellites into orbit ? instead, it's to help spacecraft manouevre once they're in space, which previously required bulky, expensive engines."
