Going where no model has gone before, clad only in a bikini, Kate Upton endures zero gravity for a photo shoot for Sports Illustrated’s 50th Anniversary Swimsuit issue. Finally we get a glimpse of how her assets may behave in space – NASA didn’t take our letters, urging them to take this matter seriously. For science – we present Kate Upton in zero gravity.

The 21-year-old model took a trip on a modified Boeing-727, known as G-FORCE ONE, which simulates zero gravity by performing a series of parabolic flight paths. This allowed photographers to capture Upton as she floated and bounced around the cabin in a gold bikini.

Kate Upton also features on the second cover of Sports Illustrated’s 50th Anniversary Swimsuit issue, check it out below.
