Last Friday was a special day on my mission. Don and I docked the SpaceX’s cargoship Dragon to the Space Station. Dragon brings new equipment for the crew. On the 31st of May it will return to Earth with supplies from the others and myself. The Dragon mission is the operational highlight of my mission. But it is also a milestone for international spaceflight. This is the first time that a commercial spacecraft has flown to the ISS and docked with the Station. You could say a new era of spaceflight has begun. Soon private companies will take people to and from space.
