Laser-driven graphene propulsion could enable fuel-free deep space missions

European Space Agency researchers have successfully demonstrated that ultra-lightweight graphene aerogels can be propelled by lasers in microgravity conditions, achieving rapid acceleration within 30 milliseconds during a parabolic flight experiment. The breakthrough shows that laser intensity can precisely control the speed and direction of these materials. This technology could eliminate the need for fuel in future spacecraft, allowing satellites and deep space missions to use light-based propulsion instead of traditional chemical fuels, potentially extending mission duration while creating more room for scientific equipment.
