EARTH ORBIT (KMOX) - The Space-X Dragon capsule, dubbed Endeavor by its crew, successfully docked with the International Space Station Sunday morning, completing another key objective of the first crewed commercial space flight.
"We were surprised, I think, at how well we actually slept aboard the vehicle," Behnken said. "A little bit quieter than Space Shuttle. A little more environmentally controlled so we didn't have CO2 pockets building up and giving us congestion which was super awesome."
CO2 pockets are areas where carbon dioxide gathers in the micro-gravity of a space vehicle. They can cause headaches, dizziness, increase blood pressure and make them tired.
As for the ride into orbit, Behnken called it "an exciting ride" and said they did get a couple of minor surprises, "Just in terms of the way the vehicle is kind of moving and shaking and taking you into orbit. You can tell that it's fighting against the Earth as it makes it's way into space."
