NASA was founded by America during the Space Race. It's purpose was to get Americans into space before the Russians. NASA (and subsequently America) succeeded in this regard and is still the only party to have put a man on the Moon. So, HA! Suck on that, Russia!
Recently, the last of NASA's space shuttles has successfully returned from it's last mission to the International Space Station. NASA will now all but shut down and America will be relying on Russia to shuttle supplies and personnel to and from the Space Station.
So, yeah.
