Nearly a half-century has passed since the earliest rotational artificial gravity testing was performed, such as at the Rockwell Rotational Test Facility and the NASA Langley Rotating Space Station Simulator. Periodically over the decades since then a few experiments have taken place, and proposals have been made for government-sponsored rotating artificial gravity test facilities, both on the ground and in orbit.^1,2 And yet no such project has been started since those early government programs.
