In the words of legendary English science-fiction writer Douglas Adams, “space is big.” To reiterate, it’s really big, and humankind has only explored a miniscule section of its reaches. We are making small strides, however. Currently, NASA plans to not only revisit the Moon but also to visit near-Earth objects like asteroids and, eventually, our neighbor Mars. Yet to do this, NASA needed to design the technology to send craft further into deep space than they’ve ever been before. The result is the most powerful rocket ever made: the NASA Space Launch System (SLS).
