Examination of the Long‐Term Subsurface Warming Observed at the Apollo 15 and 17 Sites Utilizing the Newly Restored Heat Flow Experiment Data From 1975 to 1977
> The Apollo heat flow experiment (HFE) was conducted at landing sites 15 and 17. On Apollo 15, surface and subsurface temperatures were monitored from July 1971 to January 1977. On Apollo 17, monitoring took place from December 1972 to September 1977. The investigators involved in the HFE examined and archived only data from the time of deployment to December 1974. The present authors recovered and restored major portions of the previously unarchived HFE data from January 1975 through September 1977. The HFE investigators noted that temperature of the regolith well below the reach of insolation cycles (~1 m) rose gradually through December 1974 at both sites. The restored data showed that the subsurface warming continued until the end of observations in 1977. Simultaneously, the thermal gradient decreased, because the warming was more pronounced at shallower depths. The present study has examined potential causes for the warming. Recently acquired images of the Lunar Reconnaissance Orbiter Camera over the two landing sites show that the regolith on the paths of the astronauts turned darker, lowering the albedo. We suggest that, as a result of the astronauts' activities, solar heat intake by the regolith increased slightly on average, and that resulted in the observed warming. Simple analytical heat conduction models with constant regolith thermal properties can show that an abrupt increase in surface temperature of 1.6 to 3.5 K at the time of probe deployment best duplicates the magnitude and the timing of the observed subsurface warmings at both Apollo sites.
(Humans are the worst...)
But, ya never know. Remember that warehouse they put Indiana's 'Lost Ark' in? Bet there are -a bunch- of those.
The article outlines some of the details as well, but it was lacking in depth, which can be found in the experiment results and details links in the page above.
Apparently just the plutonium in the power supply of only one of these units would cost today some 20 million USD.
Except the CTO is dead and his grandson is in charge. And oh, the original building is no longer there. Also, there's no more funding for storage. By the way, the computer systems are no longer compatible and the paper records have faded.
When you have a room full of 9" reel tapes with handwritten labels, it's hard to know what you're throwing away when you need more space. If you don't have the (again, probably handwritten) book that tells you what's on the tapes, then you probably just don't know what's there.
If it was a startup they would be too busy etching a giant advert into the surface of the moon to measure anything.
700 boxes are "lost": https://en.wikipedia.org/wiki/Apollo_11_missing_tapes#Search...
Other remaining copies are missing. The people involved on the mission cannot fathom themselves that the tapes were overwritten/reused, reason why these same space engineers organized the search themselves.
It is more likely the tapes are archived somewhere out of public reach. Or worse, are today part of a private museum for some rich elite.
