  <dc:description>&lt;div class=""&gt;&lt;div class="article-section__content en main"&gt;&lt;p&gt;Among the solar wind-implanted volatiles present in the lunar regolith, ³He is possibly the most valuable resource because of its potential as a fusion fuel. The abundance of ³He in the lunar regolith at a given location depends on surface maturity, the amount of solar wind fluence, and titanium content, because ilmenite (FeTiO&lt;sub&gt;3&lt;/sub&gt;) retains helium much better than other major lunar minerals. Surface maturity and TiO&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;maps from Clementine multispectral data sets are combined here with a solar wind fluence model to produce a ³He abundance map of the Moon. Comparison of the predicted ³He values to landing site observations shows good correlation. The highest ³He abundances occur in the farside maria (due to greater solar wind fluence received) and in higher TiO&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;nearside mare regions.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
