"Over the last year Facebook has been exploring ways to use aircraft and satellites to beam internet access down into communities from the sky," Zuckerberg wrote. "To connect people living in remote regions, traditional connectivity infrastructure is often difficult and inefficient, so we need to invent new technologies."
Zuckerberg has been a vocal proponent for free internet, having developed Internet.org, a Facebook-led initiative which aims to bring affordable access to select internet services to less developed countries.
"Connectivity changes lives and communities," he wrote. "We're going to keep working to connect the entire world — even if that means looking beyond our planet."
