For over two centuries NASA flew to the stars, leading mankind into the wild black yonder.  NASA robots and Astronauts went where no one had gone before, exploring and discovering new worlds and star systems.  They conducted decades-long exploration missions in rocket ships that people would be scared to board now.  In 2185, NASA’s era came to an end when the government closed the agency and gave their mandate to the Navy.  And so ended the Age of the Astronauts.
