  NEW! Version 2.1 - Software by Historic Space Systems 

The detailed computer graphics and realistic controls give visitors a feel for flying the real spacecraft. The graphics are superb!

Description

  • Visitors learn how two spacecraft dock in space, essential for future crewed space exploration.
  • Visitors fly the two-man Gemini spacecraft as if they are making the first docking in earth orbit.
  • Interfaces with rotation and translation controllers for full six-axis control of the Gemini spacecraft.
  • The simulation screen gives the viewpoint of the commander in the left seat.
  • The Agena target vehicle with highly detailed docking system floats outside the hatch window as the earth rotates below.
  • Includes realistic Gemini gauges, as well as a modern Translation Offset display.
  • Bird’s eye view of the Gemini helps orient the visitor.
  • Now formatted for widescreen HD displays.
  • Software design by Historic Space Systems.

Gemini Docking Simulator housed in a kiosk with translation controller at left and rotation controller at right, designed and built by Historic Space Systems. The simulation could also be integrated into a Gemini cockpit enclosure.

Simulation Flow

Simulation training segments include:

  • How Gemini and Agena docked, including historic NASA images.
  • Maneuvers needed to dock two orbiting spacecraft.
  • Use of  the controls and gauges to make a successful docking.
  • Level of difficulty selection, and random starting position.

During the simulation:

  • Limited time and fuel conspire to challenge the visitor’s docking skills.
  • An instructor astronaut guides the visitor in making the right moves.
  • Legends on the gauges, and changing controller images, help the visitor guide the Gemini.
  • When successful, the visitor is greeted with fanfare and congratulations. If unsuccessful, they are encouraged to try again later.

Spacecraft Model Views

The Gemini VIII spacecraft modeled in the simulation. Note the black Velcro patches on the white adapter section. To aid space walking astronauts on the last four Gemini missions, these replaced the black thermal control stripes of earlier flights.

Development

The Neil Armstrong Museum had approached Historic Space Systems for a new exhibit that would teach visitors about yaw, pitch, and roll. The concept quickly evolved into a simulation of docking techniques and skills based on the first docking in space. Neil Armstrong and David Scott performed the first docking in their Gemini VIII spacecraft on March 16, 1966.

Training Segment and Timing Details

The training portion of the program lasts about 3 minutes, with the option to quickly bypass individual segments. Training segments include:

  • About Gemini and Agena
  • Using the Controls
  • Using the Gauges

The simulation lasts about 3 minutes, which can be changed in the setup configuration.

To see how this simulation was made:.

During the simulation, audio prompts from the co-pilot, labels on the gauges, and changing control handle images help the visitor maneuver the Gemini.

Model Design

We created this simulation with the same approach, the same passion for realism and historical accuracy, as in our high fidelity exhibits. The simulation references over one hundred McDonnell Aircraft engineering drawings of the Gemini spacecraft and Agena Target Docking Adapter, and photographs from NASA and our own archives, to accurately depict the in-flight appearance of these spacecraft.

(Insulation strips sometimes seen trailing the adapter section of the Gemini are not depicted in the simulation to reduce distractions and improve performance. Likewise, a static discharge ring attached to the Agena docking collar on early missions is not included.)

At left, a computer model of the Gemini ejection seat design is under development as reference for a future Gemini simulator cockpit. Progress on the cockpit and control panel design can also be seen below. These designs are based on over 300 McDonnell Aircraft seat, hatch, and cockpit engineering drawings.

See labeled features of the Gemini ejection seat, and more images. Also get a closer look at the Gemini hatch.

One concept for a Gemini simulator is shown at left. The left side of the cockpit accurately models the actual spacecraft, while the right side features a simple entry that allows wheel chair access.

This arrangement is well suited for housing the docking simulation on the left side, and a spacewalk simulation on the right side.
