The world's completely solar-powered plane, Solar Impulse 2, has had to halt its round-the-world journey in Hawaii after overheating its batteries in a record-breaking flight.
Pilots of the experimental plane, the first of its kind, were attempting to circle the globe powered only by the sun’s rays.
But today its website was updated:
Breaking news: Irreversible damage to overheated batteries pushes the second half of round-the-world solar flight to April 2016.
Built with carbon fibres, the Solar Impulse 2 plane is much lighter than a normal plane, and has a far wider wingspan - wider even than a Boeing 747. This is because it must fit some 17,000 solar cells on the wings to power its propellers.
Swiss explorers and pilots Bertrand Piccard and Andre Bourschberg began their solar-powered journey in Abu Dhabi in March, stopping along the way in UAE, Oman, Myanmar, China and Japan.
With Solar Impulse 2, they broke a flight record by managing a non-stop flight lasting five days and nights without using any fuel.
The airplane will now remain at the University of Hawaii for repairs and further research.
