Glider Will Attempt Record-Breaking Flight to Edge of Space

In a spot in South America known for its powerful winds, scientists and engineers are gearing up to attempt a record-breaking feat: to fly a human-carrying glider to the edge of space. The expedition, known as Perlan Mission II, aims to take the glider up to an elevation of 90,000 feet (27,000 meters). To reach such great heights, the glider was built to take advantage of an atmospheric phenomenon called stratospheric mountain waves.
