Facebook will buy drone maker Titan Aerospace for about $60 million, a source familiar with the situation told CNBC on Tuesday.
The solar-powered drones can reportedly be airborne for up to five years without having to land.
The deal is part of Facebook's ambition to provide Internet access worldwide. News of a possible deal was first reported by TechCrunch.
Last summer, Mark Zuckerberg announced a project called Internet.org—a partnership with a number of other tech giants that aims to make Internet available to everyone in the world. The solar-powered drones could help Facebook provide Internet to areas around the world without it, starting with Africa.
