Solar Impulse 2

A pair of Swiss explorers have begun a mission to circumnavigate the globe via air and sun. A take-off twelve years in the making, the experimental Solar Impulse 2 plane left Abu Dhabi at 7:12 a.m. local time, bound for Muscat, Oman, on the first leg in a journey that will require 25 days in the air spread over a period of roughly 5 months.

The Solar Impulse 2 solar-powered airplane may have only just begun its attempt at a round-the-world flight, but it's already broken a world record. By traveling from Muscat, Oman to Ahmedabad, India, it broke the Solar Impulse team's previous record for longest solar-powered straight distance flight between predeclared waypoints. Read More

In anticipation of its historic round-the-world flight attempt, the route planned for Solar Impulse 2 (Si2) has been unveiled. The first solar-powered plane capable of day and night flight, the Si2 will spend 25 days aloft spread over a period of five months as it traverses 35,000 km (22,000 mi) with stops at 12 locations around the globe.

The maiden flight of Solar Impulse 2 took place on Monday morning at Payerne aerodrome in Switzerland. The solar-powered aircraft took off at 5:36 AM CET, when the weather around the aerodrome was at its calmest, with pilot Markus Scherdel at the controls. The aircraft flew for two hours and 17 minutes, reaching an altitude of 1,670 m (5,500 ft) and a ground speed of 55.6 km/h (30 kt). According to Solar Impulse, the in-flight data indicates that the aircraft slated to make the first all-solar global circumnavigation flight performed to expectations. Read More
What has a wider wingspan than a 747, weighs the same as a car, and can fly almost forever without a drop of fuel? If you were in Payerne, Switzerland on Wednesday, you would have seen the answer as psychiatrist and explorer Bertrand Piccard and engineer and entrepreneur André Borschberg unveiled the Solar Impulse 2. The result of 12 years work, the ultra-light, solar-powered airplane will attempt to fly around the world next year relying exclusively on solar power to keep it aloft for days at a time. Read More
