Solar Impulse is set to land in Phoenix very early Saturday. The mission will be broken into five legs and it is expected that the final one will begin in early July.
The Solar Impulse has a wingspan as wide as that of a Boeing 747 (208 feet) and weighs about as much as a small car, just 3,500 pounds.
Its wings are covered by 12,000 solar cells, to charge the 881 pounds batteries and is the first airplane to fly both day and night using solar energy.
