Made in Space: 3-D Printing Could Change the Way Astronauts Travel

What happens when something breaks aboard the International Space Station? In the past, spare parts had to be sent on resupply missions, which were expensive and time-consuming. Former NASA intern Jason Dunn saw a better option and founded Made in Space. He and his team developed a cutting-edge 3-D printer that now lives on the ISS, allowing astronauts to build new supplies in orbit. Dunn hopes their invention will spark a new era of dramatic progress in space exploration. Production company Freethink documents the work of Made in Space in this episode from the series The New Space Race.
