The Japanese SELENE lunar orbiter has returned some of the most detailed maps of the Moon to date.
The new collection of high-definition maps includes topological data and mineral location.
Critically, the locations of uranium,
thorium
and potassium have been mapped, essential for mission planners when considering the future of manned settlements on the Moon.

Seeing the lunar relief mapped to such fine detail makes for an impressive sight. So far six million data points have been collected and there's more to come…


The SELENE mission was launched on September 14th, 2007 from Tanegashima Space Center on a H-IIA carrier rocket. SELENE stands for "Selenological and Engineering Explorer", but Selene was also the Greek lunar deity. The orbiter arrived into lunar orbit on October 3rd and began science operations soon after. Since then, the spacecraft has been using a large number of instruments to characterise the surface of the Moon from analysing its mineral distribution to measuring its terrain. It has been described as the largest Moon mission since the US Apollo program.


According to the JAXA press release, these new maps are ten-times more accurate than previous maps. Using the laser altimeter (LALT) instrument, 3D data of the shapes and altitudes of surface features are promising to give the most advanced relief mapping capabilities ever performed on a planetary body other than the Earth.
It has also been indicated that deposits of uranium, potassium and thorium have been pinpointed through the use of one of its onboard spectrometers. This will have massive implications for the future of manned exploration of the natural satellite. It is likely that a nuclear source of energy would be required for future lunar settlements, if there are quantities of uranium to be mined, this will have an impact on where the settlement should be located.

So, when venturing out onto the cold, lonely lunar surface, be sure to pack the newest edition of the Selene high-definition map to plot your journey…
