Have you ever wondered where astronauts on the International Space Station get the oxygen they breathe? Though they are about 250 miles above the Earth, they are actually breathing air from the Floridian coast! The majority of the crew’s oxygen comes from special payloads sent from NASA’s Kennedy Space Center where aerospace technician Craig Tretheway packages it. Craig shows us how he prepares these essential oxygen deliveries and explains how his past career as a master motorcycle technician prepared him for his unique job at NASA.
