Vint Cerf knows a thing or two about the internet. Along with Bob Kahn, Cerf is credited with developing the initial TCP internet standard over thirty years ago, and now spends his time looking into the future of computer networks in his role as Google's chief internet evangelist. As part of his research, Cerf has worked with NASA for many years developing an "interplanetary internet" that can facilitate communications in high latency environments like space — something that the agency used to control a LEGO robot on Earth from the International Space Station back in 2012. Wired's in-depth interview takes a look at where it all began, the challenges the project faces, and where it can go next.
