Mark Zuckerberg is doing a Facebook Live with space station astronauts

Facebook CEO Mark Zuckerberg has already done a handful of Facebook Live broadcasts, talking about Facebook and its initiatives as well as interviewing members of the company. 

For his next Facebook Live, however, Zuckerberg is doing something a little more ambitious.

On Wednesday, Zuckerberg will call the International Space Station to speak with NASA astronauts Tim Kopra and Jeff Williams and British astronaut Tim Peake. 

The call will start at 12:55 p.m. ET and last about 20 minutes, according to NASA. It will also be hosted on the space agency's Facebook page.

Zuckerberg will speak with the astronauts, who are living and working on the Space Station to ask questions submitted by space fans on NASA's Facebook page. 

If you have some burning questions about the life of an astronaut, you can head to the page now to suggest some questions before the broadcast goes live next week.

The broadcast will give Earthlings an idea of what exactly goes on aboard the station, including what it's like to conduct experiments in a weightless environment.

Much of NASA's public outreach hinges upon the agency's masterful use of social media. 

NASA's main Twitter account, for example, has more than 16 million followers with plenty of other popular handles boasting thousands of additional followers. 

Tim Kopra recently took over the agency's Snapchat page, showing people on Earth what it's like to live on the station using the relatively nascent social media platform.

Aside from Facebook Live, NASA also uses NASA TV to stream interviews and other space events live to people on Earth.
