We’ve reported before on the conceptual mission known as the Interstellar Probe. This ambitious mission would visit the interstellar medium about 1,000 AU away from the Sun. But how exactly would the probe get there in a reasonable time frame? It has taken Voyager 35 years to travel less than 10% of that distance. The answer might lie in an old technology that has been given new life by advances in material science – the solar thermal propulsion system.

Ion Engines Could Work on Earth too, to Make Silent, Solid-State Aircraft
Ion engines are the best technology for sending spacecraft on long missions. They’re not suitable for launching spacecraft against powerful gravity, but they require minimal propellant compared to rockets, and they drive spacecraft to higher velocities over extended time periods. Ion thrusters are also quiet, and their silence has some scientists wondering if they could use them on Earth in applications where noise is undesirable.
