Live from the International Space Station!

We are hosting a live Downlink with astronaut Ricky Arnold on the International Space Station! A downlink is a twenty-minute video Q&A session between a U.S. educational organization and astronauts on board the International Space Station (ISS.) Astronauts and cosmonauts have been living, working, and researching onboard the ISS and want to share their knowledge and experiences with you! Be in the room while children ask Ricky questions live. These questions have been approved ahead of time, so we will not be able to field questions from the audience during the Downlink.

Come early at 2 PM for a short fun presentation and demonstration on the ISS and human spaceflight. This entire event is included free with general admission to the Discovery Center.

Prior to being a NASA astronaut, Ricky Arnold worked in marine sciences and as a teacher. He was a member of the 36th flight of Discovery and the 28th shuttle flight to the space station to deliver the final pair of power-generating solar array wings and a truss element to the station.

To learn more about Ricky Arnold, other astronauts on board the International Space Station past and present, the different expeditions, and more visit
