A solar-powered rocket might be our ticket to interstellar space (8 minute read)

The John Hopkins University Applied Physics Laboratory solar simulator is a tool that can shine with the intensity of 20 Suns. Using the solar simulator, researchers were able to demonstrate solar thermal propulsion using helium. The concept still has a long way to go before it can be used on a mission. Solar thermal propulsion could potentially help us reach past the edge of the Solar System. By using the heat of the sun, solar thermal propulsion can power spacecraft more efficiently than chemical rockets. One of the biggest barriers to making this technology a reality is handling the extreme temperatures involved.
