LIFE WITHOUT GRAVITY: ONE ASTRONAUT'S VIEW FROM SPACE
NASA astronaut Don Pettit, PhDNASA astronaut Don Pettit, PhD, a veteran of three spaceflights, will discuss life and science aboard the International Space Station. Pettit and his space station crew members spent the majority of their time aboard the orbiting laboratory performing scientific research. Their efforts supported more than 200 investigations involving more than 400 researchers around the world. The studies ranged from integrated investigations of the human cardiovascular and immune systems to fluid, flame and robotic research. They also welcomed the first commercial cargo vehicle to the station, the SpaceX Dragon, which Pettit caught and berthed to the complex using the station's robotic arm.
