Neatorama: This year marks the 40th anniversary of Star Wars. The world has changed a lot in those years, so it's nice to have a familiar world of light side vs. dark side, Jedi vs. Sith, and Rebel vs. Empire to submerge oneself in. Some of the first children who grew up with Star Wars are now introducing their grandchildren to a galaxy far, far away. Some of those first-generation fans are now working to send humans to Mars.
