NASA astronaut Kate Rubins presents highlights from Expedition 48/49, her mission to the International Space Station, to team members and Space Camp students from the U.S. Space & Rocket Center in Huntsville, April 6 at NASA's Marshall Space Flight Center. During her mission, Rubins became the first person to sequence DNA in space, researching technology development for deep-space exploration by humans, Earth and space science. She also conducted two spacewalks, in which she and NASA astronaut Jeff Williams installed an International Docking Adapter and performed maintenance of the station's external thermal control system and installed high-definition cameras.
