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.

NASA astronauts Don Pettit and Matt Dominick answered questions from the audience and discussed daily life on the ISS.

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