The Solar Impulse completed its coast-to-coast U.S. tour on Saturday when it landed at New York John F. Kennedy International Airport. The electrically powered aircraft flew the 267-mile final leg from Washington’s Dulles International Airport in little more than 18 hours. The tour, which kicked off at the beginning of May, represents the last flights for the aircraft. It will be replaced by a more capable version that will attempt a global circumnavigation in 2015.
A decisive milestone was reached yesterday as the solar-charged, electric-powered Solar Impulse successfully completed the second-to-last leg of its Across America mission by landing at Washington Dulles International Airport–locally it was Sunday, June 16 at 12:15 a.m.–stimulating renewed enthusiasm for discovery and innovation.
The massive, gangly Solar Impulse landed at 12:30 a.m. in Phoenix on Saturday, having completed the first leg of the solar-powered airplane’s Across America mission. The flight departed Moffett Airfield in Mountain View, Calif. on Friday at 6:12 a.m. PDT and landed at Phoenix Sky Harbor International Airport on Saturday at 12:30 a.m. MST.
The flight took 18 hours and 18 minutes, all powered by 12,000 solar cells mounted in the wings, driving four 10-hp electric motors and propellers. To fly at night, energy is stored in 881 pounds of lithium-ion batteries.
Switzerland-based Solar Impulse is planning “Across America” flights this spring to showcase its sun-powered aircraft to the U.S. public and demonstrate and develop the possibilities of solar energy. Meanwhile, in Switzerland, the company is developing a second, larger aircraft that it hopes to fly around the world in 2015.
The Solar Impulse project recently received a burst of sunshine in the form of financial support from a commercial insurance firm, bolstering the team’s plans to complete the world’s first global circumnavigation by a piloted, solar-powered aircraft.
