NSTAR (NASA Solar Electric Propulsion Technology Application Readiness)

NSTAR (NASA Solar Electric Propulsion Technology Application Readiness) is a program that develops and demonstrates advanced electric propulsion systems for spacecraft. These systems use solar energy to generate electricity, which then powers ion thrusters—very efficient engines that produce gentle but continuous thrust. This technology enables spacecraft to travel farther and carry heavier payloads with less fuel, making missions to distant planets and deep space more feasible and cost-effective. NSTAR has been successfully tested and used in missions like NASA's Dawn spacecraft, showcasing the potential for reliable, efficient propulsion in future exploration efforts.
