Gravity Quote by Donald E. Brownlee
![“There's almost no gravity at the surface. If you were standing on [the surface], you could jump into orbit.” quote by Donald E. Brownlee](https://sms4smile.com/quotes/img-quotes/761/donald-e-brownlee-79672_gravity_there-s-almost-no-gravity-at-the-surface_1323510.jpg)

![“I've used the Phoenix Centrifuge to replicate what the body's going to go through on the flight up. I've also done some gravity tests with ZERO-G [a charter-flight service in Arlington, Va., that uses modified Boeing 727s to simulate weightlessness], which went great.” quote by Richard Branson](https://sms4smile.com/quotes/img-quotes/aa1/richard-branson-256_adventure_i-ve-used-the-phoenix-centrifuge-to-repl_903.jpg)
