NASA pilots recently put the X-59 supersonic aircraft through the wringer—performing roller-coaster-style climbs and descents, among other actions, as part of its ongoing test campaign. The space agency released a video of its experimental aircraft performing a series of maneuvers as it soared over California’s Mojave desert. The X-59, built by aerospace contractor Lockheed Martin, is designed to break the sound barrier without the explosive, thunder-like clap that comes with traveling at supersonic speeds. The recent series of tests is helping NASA gather data on how the aircraft operates in flight, as well as gain more insight into its performance. This process is known as envelope expansion, whereby engineers test a new vehicle beyond its validated limits.
