NASA’s Space Launch System (SLS) moon rocket officially became the most powerful rocket ever flown when it lifted off in the early morning hours of Nov. 16, putting out a prodigious 4 million kg (8.8 million lbs) of thrust. That comfortably beat the old record holder—the Apollo era’s Saturn 5, with its 3.4 million kg (7.5 million lbs) of thrust.
