Live video is all the rage for Facebook right now, and next week CEO Mark Zuckerberg will show off the feature with some help from NASA. On Wednesday, June 1st, Zuckerberg will host a 20-minute livestream with NASA astronauts Tim Kopra and Jeff Williams along with the ESA's (European Space Agency's) Tim Peake, all three of whom are currently working onboard the ISS. The trio will take questions submitted to NASA's Facebook page, which is also where the stream will be shown. Things kick off at 12:55 PM ET, so set a reminder if you want to tune in.
