Kate Upton. Zero gravity. How could you EVER forget? 

Well on the off chance that our out-of-this-world shoot with America's favorite bombshell somehow slipped your mind, we're using Throwback Thursday as the perfect excuse to dig up these pretty unbelievable photos once again. 

Not even the "immutable laws of physics" could keep our two-time SI Swimsuit cover model down. After conquering Antarctica just a year before, "we set our sights higher to a less terrestrial locale" and invited our readers to come along "as we experience[d] weightlessness on G-Force One." Talk about one EPIC shoot.

So in an experience where "gravity falls away like a bathrobe before a hot tub," how is a swimsuit model meant to look sexy? Leave it to Kate to prove it can be done! Because while "weightlessness is a great leveler," we will all forever be inferior to the beauty of Kate Upton at zero-g.
