This composite image includes a photograph of pilot Joe Algranti testing the Multi-Axis Space Test Inertia Facility (MASTIF) inside Altitude Wind Tunnel at NASA’s Lewis Research Center with other images designed to simulate the interior of a Mercury space capsule. As part of the space agency’s preparations for Project Mercury missions, the seven Mercury astronauts traveled to Cleveland in early 1960 to train on the MASTIF. Researchers used the device to familiarize the astronauts with the sensations of an out-of-control spacecraft. The MASTIF was a three-axis rig with a pilot’s chair mounted in the center. An astronaut was secured in a foam couch in the center of the rig. The rig then spun on three axes from 2 to 50 rotations per minute. The astronauts used small nitrogen gas thrusters to bring the MASTIF under control. In the fall of 1959, prior to the astronauts’ visit, Lewis researcher James Useller and Algranti perfected and calibrated the MASTIF.
