Space exploration is the discovery of space with the help of space technology. It is an exploration of outer space using both human spaceflights and robotic spacecrafts. Space exploration has always been a proxy for the political rivalries, mainly for Cold War and this competition was known as "Space Race".
After the Space Shuttle program has been discontinued (this is the subordinate clause), the nature of space exploration has changed dramatically because humans no longer re-use their spacecrafts.
