On Wednesday (Feb. 12), NASA will host its first Twitch stream from the International Space Station (ISS), giving viewers the chance to ask NASA astronauts questions in real time, while they orbit Earth some 250 miles (402 km) from our planet's surface.

The NASA astronauts will answer questions about daily life up in orbit, as well as the research conducted in microgravity.

To watch the stream, simply head to NASA's Twitch channel at 11:45 a.m. ET on Feb. 12. The stream will act like any other Twitch stream where you can chat and watch, except this time it'll be with someone who is 250 miles above the Earth's surface.
