                                 In a first, an European Space Agency-led team has built and fired an electric thruster that ingests atmospheric air to be used as propellant, allowing for satellites to fly in very low orbits for several years.
                    Air-breathing electric thrusters could also be used for missions around the outer atmospheres of planets like Mars, drawing on their carbon dioxide, said ESA.
