The space agency has a plan to “skip a generation” of passenger aircraft design to fight climate change.

There’s a new NASA X-plane in town, and like its predecessors, it’s a little bit goofy-looking. Unlike most of the space agency’s experimental aircraft, however, the new X-plane isn’t built to break speed barriers, carry astronauts, or test the possibilities of unmanned air combat. This one is designed to fight climate change.
