Special "space" suit for the Reduced Gravity Walking Simulator located at the Lunar Landing Facility. The purpose of this simulator was to study the subject while walking, jumping or running. Researchers conducted studies of various factors such as fatigue limit, energy expenditure, and speed of locomotion. A.W. Vigil described the purpose of the simulator in his paper "Discussion of Existing and Planned Simulators for Space Research," "When the astronauts land on the moon they will be in an unfamiliar environment involving, particularly, a gravitational field only one-sixth as strong as on earth. A novel method of simulating lunar gravity has been developed and is supported by a puppet-type suspension system at the end of a long pendulum. A floor is provided at the proper angle so that one-sixth of the subject's weight is supported by the floor with the remainder being supported by the suspension system. This simulator allows almost complete freedom in vertical translation and pitch and is considered to be a very realistic simulation of the lunar walking problem. For this problem this simulator suffers only slightly from the restrictions in lateral movement it puts on the test subject. This is not considered a strong disadvantage for ordinary walking problems since most of the motions do, in fact, occur in the vertical plane. However, this simulation technique would be severely restrictive if applied to the study of the extra-vehicular locomotion problem, for example, because in this situation complete six degrees of freedom are rather necessary. This technique, in effect, automatically introduces a two-axis attitude stabilization system into the problem. The technique could, however, be used in preliminary studies of extra-vehicular locomotion where, for example, it might be assumed that one axis of the attitude control system on the astronaut maneuvering unit may have failed." -- Published in James R.

KENNEDY SPACE CENTER, FLA. - Volunteers from the KSC Fire-Rescue team dressed in launch and entry suits settle into seats in an orbiter crew compartment mock-up under the guidance of George Brittingham, USA suit technician on the Closeout Crew. Brittingham is helping Catherine Di Biase, a nurse with Bionetics Life Sciences. They are all taking part in a “Mode VII” emergency landing simulation at Kennedy Space Center. The purpose is to exercise emergency preparedness personnel, equipment and facilities in rescuing astronauts from a downed orbiter and providing immediate medical attention. This simulation presents an orbiter that has crashed short of the Shuttle Landing Facility in a wooded area 2-1/2 miles south of Runway 33. Emergency crews will respond to the volunteer “astronauts” simulating various injuries. Rescuers must remove the crew, provide triage and transport to hospitals those who need further treatment. Local hospitals are participating in the exercise.

Dr. Wernher von Braun, Marshall Space Flight Center (MSFC) Director, was suited with a space suit and diving equipment at MSFC Neutral buoyancy Simulator (NBS).

NASA and SpaceX held a joint training event for pre-launch operations, which provided an opportunity for the crew and ground operators to rehearse all of the activities, procedures, and communication the teams will exercise on launch day from crew suit-up in Kennedy Space Center’s Operations & Checkout (O&C) building in Florida through launch; this training event also included simulated emergency egress scenarios. NASA astronauts Bob Behnken, in front, and Doug Hurley, in back, are participating in a suit-up for launch, using the same Ground Support Equipment hardware, such as the seats and suit leak check boxes, that the crew will use for launch, with the SpaceX ground closeout team and suit engineers that will help the crew suit up and ingress the Dragon on launch day. Following crew suit-up, the crew ingressed the capsule simulator in Hawthorne, California, as they would on launch day, and the teams performed a simulated launch countdown and several emergency egress scenarios.
