This morning, the Solar Impulse solar-powered aircraft touched down at Payerne air base in Switzerland after its first all-night flight which lasted more that 26 hours. The aircraft, which weighs about 3,500 pounds, reached a maximum speed of 68 knots and a maximum altitude of 8,564 meters above sea level.
This was the first ever all-night flight by a solar-powered aircraft. The energy is collected and stored on 12,000 solar panels on the plane’s wings during the day and is used to power four electric motors. So, what’s next for the Solar Impulse? Circumnavigating the globe in 2010? Maybe.
