The plane that flies on sun power is ready to shine once again.
Last March, Solar Impulse 2 began its journey to become the first solar-powered aircraft to circumnavigate the globe. But after taking off in Abu Dhabi and crossing Asia, the plane ran into some big problems during the long, arduous leg over the Pacific Ocean. The batteries got hotter in the tropical weather than the team anticipated, throwing a wrench into the entire mission. Solar Impulse 2 and its pilots Bertrand Piccard and Andre Borschberg left Japan and flew five days over the Pacific, but made it only as far as Hawaii before they had to shut things down last July.
Nine months later, they say the technology is fixed and the days are finally getting long enough that the plane can get the sunlight it needs to resume its journey. If all goes according to plan this time, Solar Impulse 2 will take off from Hawaii today headed for Mountain View, CA. It'll make a stopover or two in the U.S. before reaching New York City, and then crossing the Atlantic in a quest to eventually reach Abu Dhabi and complete the trip around the globe.
