Solar planes have already traversed the Alps and flown around the world, but one team has its sights set a little higher: the edge of space. SolarStratos is planning to fly a solar-powered plane to an altitude of over 80,000 ft (24,000 m), from where the curvature of the Earth as well as daytime stars will be visible.
The aim of the project is to demonstrate the potential of renewable energy and to explore the possibility of flying people to such altitudes using solar technology.
