Perhaps the only one that was saved. I’ll add more shots below.

From Lunar Legacies: “The actual Lunar Module ascent stage taken from the Command Module Simulator 2 at KSC after training was complete. It measures 5″ tall and 8” at its widest point, and seems to be made of molded and then painted fiberglass. This was the actual Lunar Module model which was made to move around the camera in the simulator tunnel to show the attitude of the LM in relation to the CSM in response to the hand controller inputs from the Command Module Pilots. The model contains a docking port for practice in that maneuver, and several lights, including the main strobe light, that were wired up and in lit up in the simulator. The wires and most the bulbs still remain, and can be made to work again.

There were a total of three Command Module simulators in use at the time, CMS-1, CMS-2 and CMS-3. CMS-1 was in Houston and was used for system familiarization, while CMS-2 and CMS-3 were at KSC and were used for mission specific training, such as docking. This particular Lunar Module model was in the darkened CMS-2 tunnel, and was used to train the Apollo 9, Apollo 11 and Apollo 13 crews. That means that Dave Scott, Michael Collins and Ken Mattingly, along with their backups (Gordon, Anders and Swigert) all trained for rendezvous and docking using this model. CMS-2 also was used to train the Apollo 1 and Apollo 7 crews but without a need for this LM model of course. The other simulator, CMS-3, was used to train all the other Apollo crews. After training for the Apollo landing missions was complete, this model was taken from the CMS-2 simulator tunnel, and has been kept in storage ever since that time. Probably the only one of the three in existence that was saved.”

I want to see if the internal lights are still working… I presume I would start with a low voltage and work up. Any better suggestions?

  2. I would expect them to be DC, so if you have any sort of power supply that on a rheostat, I doubt it would exceed 12 volts.

    You may look at what model trains used for lighting back then, I suspect these guys often drew from easily available inventory.

  3. I think this pre-dates LED’s, so starting from low voltage and ramping up slowly should be OK, but if in any doubt (as I suspect you probably know) then current rather than voltage is what you need to keep your eye on. Try measure the forward and backward resistance first, and if they differ, you’re talking solid state rather than incandescent, in which case polarity and current are more important than voltage.

  4. If these are standard "grain of wheat" bulbs used in the 1960s as instrument panel lamps and in model railroading, they’ll be 12v at about 75ma. There was also something called a "grain of rice" bulb that I don’t know anything about. I second jitze’s suggestion to limit current as well as voltage while trying to determine the characteristics.

  5. thanks y’all.

    I now have the measurement tools and model railroad equipment to give it a go…
