By the early 1970s the Dry Moon was settled science, especially among lunar geologists in the United States. Had that gone differently, the last mission of the Moon Race, by the Soviets, might have changed everything. It discovered water within the Moon. Instead it was ignored. On August 9, 1976, Luna 24 launched toward the Moon on a Proton rocket, and nine days later landed safely in the southern part of the unexplored Mare Crisium... What it brought back was very special. The core sample was found by scientists M. Akhmanova, B. Dement'ev, and M. Markov of the Vernadsky Institute of Geochemistry and Analytic Chemistry to contain about 0.1% water by mass, as seen in infrared absorption spectroscopy (at about 3 microns wavelength), at a detection level about 10 times above the threshold.

Fig. 3 shows the diffuse reflection spectra and scattering polar diagrams for two wavelengths (2.2 and 4.5 µm) for samples returned to Earth by Luna 24... Fig. 3 also shows slight minima near 3, 5 and 6 µm. These absorption bands are rather well identified by the valence bands and vibrations of a water molecule. The intensity of these bands (two or three times larger than the noise level) is a maximum for the sample taken from the depth of 143 cm, and becomes less at 184 cm; it is comparable with the noise level at 118 cm. A comparison with basalt spectra with known water concentrations allows an estimate to be made of the water content in the sample; at a depth of 143 cm, this is 0.1%... We have taken all the necessary precautions to protect the samples of lunar soil from atmospheric water, and thus have confidence in our results. The 5.5 to 7.5 µm structure in the reflection spectrum obtained by Saljut 5 may also favour the lunar origin of the water.
