The video explores the history and evolution of the Atlas rocket family, from its origins as a military missile during the Cold War to its role in the space race and human spaceflight. Key innovations, such as the stage and a half design, allowed Atlas rockets to become reliable launch vehicles for NASA. Over the years, the Atlas family underwent significant redesigns, culminating in the Atlas V, which has been instrumental in numerous scientific missions. As the era of Atlas rockets comes to an end, the Vulcan rocket is set to take over, promising greater flexibility and payload capacity.
