The launch in 1972 of Apollo 16
On each mission two astronauts
went down to the Moons surface.
The third astronaut had to stayin the Command-Service Module
that was orbiting the Moon
6 Apollo Landings on the Moon

One View seen by Apollo 17
astronauts orbiting the Moon
The maria are smooth, lower,and darker than the highlands
The arrow is pointing to one
crater that has a diameter of
20 kilometers!

One key task for the people
who will live and work at a
lunar base is field geology.
The real work of geology is
mapping rock distributions
and observing the different
features in the field on both
large and small scales.
A common feature in basaltic lava flows on Earth is the lava tube.
In the illustration, astronauts are examining a lava tube on the Moon.

This astronaut collected many
walnut-sized rocks with a rake
These samples proved to beextremely valuable because
they provided a very broad
sampling of the rock types
present at the landing site.

Returned by the Apollo 15 Mission
The holes are frozen gas bubbles called vesicles,
a common feature of terrestrial volcanic rocks

Anorthosites are 98%
Plagioclase Feldspar
This kind of mineral
rock is formed byeither floating or
sinking in a magma

Rockfragments
mixed
together
are called
breccias
With so many craters of all sizes in the lunar highlands, it is no
wonder that the rocks have been modified by meteorite impact

This is a key
element for
rocket propellants
can be extracted
from the surface
materials by
reaction withhydrogen
The Moon has no running water or air to breathe,but its soil contains enormous amounts of oxygen
This is a key
element for
life support
can be extracted
from the surface
materials by
reaction withhydrogen
It might be exported for use in Earth
orbit or to fuel spacecraft on trips to
Mars and elsewhere in the Solar System

Orange drops of lava cooled
very quickly and did not have
time crystallize so most of the
droplets are composed of glass
The dark drops did have time
to partially crystallize, and so
formed the opaque mineral
ilmenite, which appears black.
Returned by the Apollo 17 mission
This view Is 2.5 millimeters across

NASA JOHNSON SPACE CENTER, HOUSTON, TEXAS
Samples remain in glass and
steel cabinets, bathed in an
atmosphere of pure nitrogen,
to protect the samples fromaltering by reaction with air.
Technicians who curate lunar
samples dont really touch them.They can pick them up using
Teflon - covered gloves that are
mounted on the sealed cabinets

Painting by William Hartmann
Traditional ideas for the lunar
origin had flaws so scientists
devised an idea that the Moon
formed as a result of an impactof a projectile the size of Mars.
The impact melted our planet
and some of the material spunoff ending up in orbit around
Earth forming our Moon.

The far-side of the Moon was never
seen until the time of the Apollo era.
The dark areas are called maria and
they are barely visible from Earth
The lighter areas are on average just
a few kilometers higher than most of
the maria and are intensely cratered.

NOWUse your own
imagination to
envision YOU
on the MOON
Here you are, our Earths first
Space Generation, explainingto a member of the next space
generation just exactly where
our ancestors came from.
This is what the Earthrise
looks like from lunar orbit

During your
lifetime, a
lunar base
will exist.
TATA agrees
to explore all
alternatives
to all of ourenergy needs.
In your lifetime
