New minerals were discovered on the Moon.
The most well known is called armalcolite, named after the Apollo
11 astronauts Armstrong, Aldrin, and Collins. Armalcolite is a
high titanium mineral that forms at high temperatures and pressures
such as those that exist when a meteorite impacts the surface.
Armalcolite was unknown prior to the Apollo 11 mission, but has
since been found on Earth in the vicinity of impact craters.
