A solar plane is heading to Arizona after taking off from California.
It's the first plane of its kind, powered by about 12,000 solar cells that cover massive wings and charge its batteries. Both allow it to fly day and night without jet fuel.
It plans to stop at Sky Harbor Airport in Phoenix, along with several others across the nation as it heads east.
Each flight leg will take 20 to 25 hours, with ten-day stops in each city.
The goal is to showcase the potential of solar power.
