A new map of the Moon has revealed an abundance of titanium ore that is up to 10 times richer than on Earth,
a finding that could one day lead to a lunar mining colony
Mark Robinson of Arizona State
University, who presented the research at a conference in Nantes,
western France with Brett Denevi of Johns Hopkins University in
Baltimore, sifted through the data for telltale jumps in the ratio of
ultra-violet to visible light. They established this signature thanks
to rock samples brought back to Earth by Apollo 17 astronauts in 1972
and images of the area around the mission’s landing site by the Hubble
space telescope.
“Looking up at the Moon, its surface appears painted with shades of grey, at least to the human eye,” explained Robinson.
“But with the right instruments, the Moon can appear colourful.
“The maria [lunar plains] appear reddish in some places and blue in others.
“Although subtle, these colour
variations tell us important things about the chemistry and evolution of
the lunar surface. They indicate the titanium and iron abundance, as
well as the maturity of a lunar soil.”
Titanium is as strong as steel but nearly half as light, which makes it a highly desired — and also very expensive — metal.
On Earth, titanium is found, at the
very most, in around one percent of similar types of ore. But the new
map found abundances in the lunar maria that range from about one
percent to 10 percent, the conference organisers said in a press
release. In the lunar highlands, abundance was around one percent.
The meeting gathers, for the first
time, members of the European Planetary Science Congress and the
American Astronomical Society’s Division for Planetary Sciences.
The find offers a double potential bounty, they said.
“Lunar titanium is mostly found in the mineral ilmenite, a compound containing iron, titanium and oxygen,” they said.
“Future miners living and working on the Moon could break down ilmenite to liberate these elements.
“In addition, Apollo data shows
that titanium-rich minerals are more efficient at retaining particles
from the solar wind, such as helium and hydrogen. These gases would also
provide a vital resource for future human inhabitants of lunar
colonies.”
