    Apollo 17 Flown Heat Flow and Convection Experiments Parts Directly from the Personal Collection of Mission Command Module Pilot Ron Evans. Four separate pieces of equipment that were part of this demonstration, studying convective flow and heat transport driven by surface tension, conducted by Ron Evans during the Apollo 17 trans-lunar coast.
    (1) The first is a white cable with connectors at each end, one three-pin male and one six-pin female, Part Number "SEB33100038-301" and Serial Number "1021". This 108" cable is held together by a 5.5" x 1" cloth utility strap with snap closures, Part Number "V36-601118-11" on which Evans has written "HEAT/ FLOW/ PWR/ CABLE".
    (2) The next item is a two-bulb portable 28 volt utility spotlight, Serial Number "0004" with overall dimensions of 2.25" x 2/25" x 1" plus mounting bracket and cable attachment with a six-pin female connector; there is a small piece of Velcro on one side.
    (3-4) The last two items are similar 8" black metal rods, one with a piece of Velcro attached. They are made so that they can connect together two different ways.
    Ron Evans commented about the experiments during the technical crew debriefing: "Heat flow demonstration - it worked great. There were no real problems on it. It was a real time operation with ground. Everything is recorded on the down-link." An interesting and unique grouping of flown and experimentally-used items. Excellent condition.

    The abstract from an article "Heat Flow and Convection Experiments aboard Apollo 17" by Philomena G. Grodzka and Tommy C. Bannister sums up the technical results of these experiments: " Experiments conducted aboard Apollo 17 by astronaut Ronald E. Evans showed that in uncovered liquids convection driven by surface tension can occur at lower temperature gradients in low gravity (about 10-8g) than in 1g. In completely confined fluids (no liquid-gas interface) vibrations caused by spacecraft and astronaut movements increased the heat transfer considerably over the pure conduction case." (Science, January 17, 1975, pages 165-167).

    Heritage sold the Omega 861 Speedmaster Pro watch that Evans used during Heat Flow and Convection demonstration in our April 1, 2009 Space Exploration Auction #6022 (lot 41028) for $23,900.00.

    Included with this lot is are two 8.5" x 11" color glossy prints of NASA images AS17-162-24056 and AS17-162-24057 which show these items in use during the experiments on the Apollo 17 trip to the moon.

    Also included with this lot is a signed Letter of Certification from Jan Evans (Mrs. Ron Evans) stating: "I certify that the items offered with this letter were flown to the moon and used by my husband Ron Evans CMP, as part of the Heat Flow Experiment conducted on board Apollo 17, December 1972. Included are: white spotlight S/N 0004, power cable, S/N 1021 with "HEAT FLOW PWR CABLE" hand written by Ron, and two attachable black metal rods with Velcro. They have been with our family since the completion of the flight."
