Website Detail Page

published by the NASA Glenn Research Center
This NASA website dispels the myth that there is no gravity in an orbiting spacecraft.  It includes the classic diagram of a cannon fired from a mountaintop that gives a projectile various velocities and shows the various orbits that result. The site explains how a drop tower is not an "anti-gravity device."
