When reading by moonlight….

The Portable Utility Light was used to provide extra lighting for Apollo 16 Commander John Young and Charlie Duke. The light connected to the overhead utility light panel and switches provided Young and Duke with one-step dimming for light-intensity control.

Before jettisoning the Lunar Module, Charlie Duke cut the light cord and brought it back with him as a souvenir of his lunar voyage. Without unauthorized activities like this, the flown lunar module hardware would be left behind, as it was for the early flights. There is a specified list of LM items to be brought back into the CM for the return to Earth, and the night light and LM COAS are not on that list.

Heritage description: “Apollo 16 Lunar Module Flown Utility Light Cord
Directly from the Personal Collection of John Young

Approximately 42″ long, this coiled utility light cable assembly features copper wire inside clear insulation, two Velcro-backed strips for mounting to the wall of the spacecraft, and a six pin, Beta cloth-wrapped electrical connector at one end. This was utilized in the Lunar Module Orion on the lunar surface to power a small utility light for the use of the crewmen. It remained in the LM on the moon for nearly three full days. The number on both straps reads “LDW340-53608-1”.

Included with this lot is a letter of authenticity signed “John W. Young” on his personal letterhead, stating: “I hereby certify that the accompanying coiled Utility Light Cord was flown to the lunar surface aboard the LM with Charlie Duke and myself during the Apollo 16 mission April 16-27, 1972. Charlie gave this cord to me after our mission and it has been a part of my personal collection since.”

  1. OK…
    Inquiring minds want to know;
    what sort of price do you pay for artifacts like this…?
    Mind you, it probably cost NASA 300,00$ to develop/make it…(not kidding here)
    A PETZAL headlight and spare batteries is 50 bucks .

  2. heh, brought back from the moon? Priceless!

    Some of the specialized flight hardware can be bought for much less than its original development cost. But those can be a bit unfair comparisons because if it’s a specialized item with a global market of ~10 units and a huge cost for failure, the fully amortized cost gets a little nutty.

    I have one very large artifact that is still in frequent use today, the Pratt & Whitney RL-10 Rocket Engine, and so there is a current market price to compare to: $38 million!

    That makes a complete unit very rare… perhaps the only one in private hands.

    And it looks sooooooo cool on a test stand…

  3. 🙂
    Thought you were going to say…"If you have to ask…"…(!)
    Anyways…another fine item for your collection.
    How/what/when did they "dump" stuff out of the LEM before leaving…?
    I mean they did not bring all the EVA gear back I presume…
    And was there a critical amount of weight they had to dump…?
    Did the weigh the rocks before ascent to check "balance…etc.?

    PS I suspect your P&W has had a few miles on it….

  4. on Earth, yes, a few miles. Since the RL-10 is used as an upper stage engine, no flown one has returned to Earth intact.

    And yes, they leave most of the weight on the moon (rover, EVA gear) and then again when transferring the moon rocks through the docking ring to the Command Module. The LM deorbits and crashes into the moon (in later flights, with a purposeful crash burn so they could measure the seismic waves with lunar sensors).

    In the office, I have a list of the exact items for Apollo 16 that were to be taken home. I should post that on Monday.

  5. !!
    The RL10….."Anti Tesla"…!

  6. wow! looks like a very special engine…huuuge… night light and docking ring look good too…you seem building Jurvetson’s space museum:):)

  7. Too bad you don’t have the light and mating connector. It’s kind of useless as-is.

  8. the whole collection is, if you think about it.

    I’m suspecting Duke and Young split the baby on this one…

  9. I think most of us assume some day you will have assembled all the pieces of a Saturn/Apollo and will revisit the moon!

  10. yes, yes, working on that… Just few items to go…

    And here is the transfer instructions from the Apollo 16 LM Timeline Book.

    Note that the COAS and this LM Utility Light are not on the list, and so the return of these mementos by the astronauts were an off-script activity.

    And from the transcript of the direct ascent from the moon, there are several references to the COAS as well. I love that Young jokes: “Yeah, we get to keep the Lunar Module.”

  11. Ugh, I’m not sure I needed to know what they keep in the "purse."

  12. Oh, I have that info… been meaning to compile and post…

    Meanwhile, here is the display I just put together for the cable:
