Ion Engine Breakthrough Could Take Us To Mars At A Fraction Of The Fuel | IFLScience

A group of French physicists has optimized a type of ion thruster to significantly extend its lifetime: the new development made it sturdy enough to be able withstand a long trip into deep space. Such a thruster would require 100 million times less fuel than common thrusters that use chemical reactions to propel a spacecraft forward.
