NASA hopes to land humans on an asteroid by 2025. Soon the Kerbals will embark on the next phase of space exploration, more than a decade before their real-life human analogues. And this year they will begin to work together. These past few months the team at KSP and the team at NASA have developed a professional, although distant, relationship.
KSP has even earned the respect of NASA - many of its employees play it regularly. Beneath its childish surface lies a complex physics system churning through mathematical calculations so expertly, real rocket scientists would blush to see it. Since the day it was released, less than three years ago, KSP has grown to be so much more.
