Across the country in Greenbelt, Maryland,
scientists at the Goddard Space Flight Center
are also busy analyzing lunar samples.
Dr. Isidore Adler tells
what his group has found so far.
There is a much higher concentration
of some minerals.
For example,
there is a mineral called ilmenite,
which is an iron titanium oxide,
which appears to be unusually high
in concentration in these rocks.
And it seems to indicate
perhaps, that at some time or other,
the Moon was exposed,
at least these surface materials,
to some rather severe heating.
So these frozen samples
were actually collected
from a region on the Moon
that was in shadow from the Sun.
So it was basically a large boulder.
In the near future,
we're going back to the Moon
and hopefully going to the polar
regions of the Moon,
where some of these regions
are in permanent shadow.
These particular samples
are really great analogs
for what we might expect
to see in the polar regions
when we go back.
