The mockup Orion crew exploration vehicle is lowered into the water at the Trident Basin at Port Canaveral, Fla., for testing. Orion is targeted to begin carrying humans to the International Space Station in 2015 and to the moon by 2020. The goal of the operation, dubbed the Post-landing Orion Recovery Test, or PORT, is to determine what kind of motion astronauts can expect after landing, as well as outside conditions for recovery teams. Orion, along with the Ares I and V rockets and the Altair lunar lander, are part of the Constellation Program. Photo credit: NASA/Dimitri Gerondidakis
