It's the first attempt by a solar plane capable of being airborne day and night without fuel to fly across the U.S, at a speed of about 40 mph.
The plane started its flight in Northern California on May 3 and flew to Phoenix. It left Phoenix on May 22 and landed the next day in Texas.
After several events in St. Louis, the Solar Impulse is scheduled to fly to Dulles International Airport near Washington before ending its journey at New York's John F. Kennedy International Airport.
