All of us know the breathtaking footage of Apollo 11’s Moon landing. We sadly recall the tragic events of Challenger. Millions eagerly waited for New Horizons to arrive at Pluto in the Summer of 2015. Yet, there has been a multitude of valuable space programs that have not received such wide media attention. Here is a list of all NASA Missions, their original launch years, whether or not they are active and a brief description of their key purposes.
