No not quite exaggerated.
Perhaps few can appreciate the suspense of a decade of work launch and transit culminating into a do or die moment on atmospheric interface, but I see it as nothing more than exhilarating...perhaps even heart stopping. It's the end of a journey one way or another but the beginning of mission if it succeeds.
This is a profession. This is where millions of Dollars, thousands of hours or meticulous planning and scheduling come to fruition.
