Dmitry Rogozin, the Head of Russian space agency Roscosmos, said that he would not hire space startup SpaceX's CEO Elon Musk to get help with reusable rocketry. On being asked about inviting Musk to Russia, Rogozin said, "He's a busy man, I'm a busy man, why should I invite him?" In the past, Rogozin accused SpaceX of "killing competitors."
