Center for Lunar Science and Exploration
The Lunar and Planetary Institute (LPI) and the Johnson Space Center
(JSC) have a long and successful history of collaborative research and
exploration activities that began with the Apollo program. The LPI
and JSC have harnessed that heritage to build the new Center for Lunar
Science and Exploration to better support our nation’s new lunar
science and exploration activities.

Check out the Meetings Calendar - Maybe something of interest and

Introduction to the Moon

In the first presentation of the Moon 101 lecture series, Dr. Paul
Spudis gives an introduction to the Moon, providing an overview of the
more detailed Moon 101 lectures to follow. The presentation begins by
describing the nature of the Moon as a heavily cratered rocky planet,
and compares the general properties of the Moon to those of the Earth
and Mars. Global images and elemental composition maps are then
followed by discussions of: the thermal and micrometeorite
environments on the lunar surface; the Moon's orbit and resulting
eclipses and lunar librations as viewed from Earth; surface
topography; moment of inertia; surface morphology and physiography;
landscapes and terrains; the surface lighting environment; regolith
and dust; and the origin of the Moon. The presentation concludes with
a review of past and current robotic exploration missions to the Moon.

Lesson presented: 06⁄04⁄2008
Lesson produced: 09⁄05⁄2008

Duration: 56 minutes 5 seconds

The Lunar Environment
Dr. Mendell's presentation addresses a multitude of aspects of the
Lunar Environment. The first section reviews the many external factors
that act upon the Moon and how their effects that need to be
understood by the lunar designer or explorer. He chooses to discuss
the environmental factors through their connection to the Moon's
location in the universe, in the Milky Way Galaxy, in our solar system
near the Sun, and in proximity to the Earth. The effects of the solar
wind plasma, meteoroids, and solar insolation are important on the
Moon because it lacks a magnetic field and a substantial atmosphere.
He describes the Earth-Moon system as a “binary planet” and discusses
the Lunar Coordinate System and the importance of the Moon’s polar
regions. The second part of Dr. Mendell's presentation covers the
implications of the environment for living and working on the Moon. We
have little to no experience in habitat design for a low-gravity
planet. The Moon's 'lumpy' structure introduces irregularities in its
gravitational field, increasing the cost of maintaining low orbits. He
goes on to discuss the Moon's tenuous atmosphere, its unusual surface
reflectivity, ejecta from surface impacts (why we need to worry about
this), lunar seismic events (moonquakes, impact events – even ours),
and lastly emanations of gases from beneath the surface.

Physiography and Geology of the Moon
Dr. Paul Spudis discusses the physiography and geology of the moon
including: terrains, landforms, topography (photogeology), impact
crater formation, excavation, ejecta emplacement, secondaries, impact
melting and shock metamorphism, lunar meteorites, flux through time;
cataclysm, periodicity, correlation with terrestrial record and other

Duration: 58 minutes 40 seconds

The Lunar Surface
The fourth presentation in the Moon 101 series, Dr. Jeff Plescia
discusses – dust, rocks, slopes, trafficability (geotechnical
properties); formation and evolution of regolith, interface with
bedrock; crater size-frequency distributions, exotic components,
highland⁄mare mixing, vertical and lateral transport of material;
chemical and mineral composition, physical state, properties, and
surface characteristics.

Lesson presented: July 16, 2008
Lesson produced: July 23, 2008

Duration: 49 minutes 27 seconds

The Lunar Crust
Dr. Gary Lofgren discusses the current understanding of the crust of
the Moon. The presentation begins with a brief overview of the Moon's
surface, and discusses the prevailing Magma Ocean Theory resulting in
the formation of the primary, or original, lunar crust. The crust was
subsequently modified by impact bombardment and volcanic activity.
Compositional variations in the lunar crust are then described as
three major terrains: Procellarum KREEP terrain, Feldspathic Highlands
terrain, and the South Pole-Aitken basin terrain. It is noted that
studying rock samples is the key to understanding the lunar crust. The
presentation then focuses on the characteristics and ages of the major
rock types found on the Moon: basaltic rocks from mare lava flows,
anorthositic rocks in the lunar highlands, impact breccias and melt
rocks, and volcanic glasses. The lecture concludes with a brief review
of the rock sampling conducted during the Apollo missions, and lessons
learned for future lunar surface exploration.

Duration: 54 minutes 11 seconds

The Lunar Interior
In the sixth presentation of the Moon 101 lecture series, Dr. Jeff
Plescia discusses the current understanding of the interior of the
Moon. The presentation begins with a brief overview of the Moon from a
geophysical perspective, and discusses the prevailing Giant impact
Theory and Magma Ocean Theory resulting in the formation of the Moon
and its differentiation into crust, mantle, and core. The presentation
then focuses on the current understanding of the chemistry,
mineralogy, and thickness of the lunar crust; the boundaries, depth,
and mineralogy of the mantle; and the size and composition of the
lunar core. Geophysical parameters of the Moon are then discussed,
including: the seismic nature of the Moon, including shallow, deep,
and thermal moonquakes and impact events; the lunar gravity field;
magnetism; and heat flow.

Duration: 1 hour 30 seconds

The Lunar Polar Environment
In the seventh presentation of the Moon 101 lecture series, Dr. Ben
Bussey discusses the current understanding of the polar regions of the
Moon. The presentation begins with a brief overview of the geometry of
the Moon's axis of rotation with respect to the ecliptic plane, the
resulting polar environment on the lunar surface, and the proposition
that a polar region, particularly the south pole, would be a good
location for a lunar outpost. Using imagery data from the Clementine
and SMART-1 missions, the majority of the presentation focuses on how
local topography at the poles result in two specific areas of
interest: permanently shadowed craters possibly containing water ice,
and topographically high areas that receive enhanced illumination from
sunlight due to their elevated position with respect to the
surrounding terrain. The presentation concludes with discussions about
how radar instruments on the Chandrayaan-1 and Lunar Reconnaissance

A Brief, Selective History of the Apollo Program
In the eighth presentation of the Moon 101 lecture series, Dr. Dean
Eppler provides a brief and selective history of the Apollo program.
The presentation begins with President Kennedy's message to Congress
on National Priorities in May of 1961, and his desire to commit the
nation to the exploration of the Moon. The presentation then focuses
on several key efforts that made the Apollo program successful,
including national will, money, heavy lift launch vehicles, lunar
landers, space suits, operational practices, and luck. An overview of
each Apollo mission to the Moon then follows, including mission facts
and statistics, results, and lessons learned. The presentation
concludes with discussions on how the Constellation Program could use
the lessons learned from Apollo to benefit the future explorations of
the Moon.

Lesson presented: 09⁄10⁄2008
Lesson produced: 10⁄10⁄2008

Duration: 56 minutes 6 seconds

Future Scientific Exploration of the Moon
In the ninth presentation of the Moon 101 lecture series, Dr. Paul
Spudis discusses current ideas for the future exploration of and
operations on the Moon. The presentation begins with a brief overview
of why the Moon is important and the value of exploration,
particularly human spaceflight. Points of discussion included using
the Moon as a school for exploration, a place to learn how to live and
work off planet, and a stepping stone to the Solar System. The
presentation then focuses on how geological exploration is conducted,
including reconnaissance and field work, field and lab analyses,
mapping, and planning surveys, traverses, and transects. The
importance of surface mobility to accomplish these tasks, and the
proper mix and use of humans and robots are highlighted. The
presentation then focuses on the use of emplaced science stations and
observatories for geophysics, astrophysics, heliophysics, and earth
observations. The presentation concludes with discussions summarizing
new exploration approaches and the challenges facing these approaches,
such as lighting conditions and lunar dust.

Lunar Meteorites
In the tenth presentation of the Moon 101 lecture series, Dr. Kevin
Righter discusses lunar meteorites and how they have contributed to
lunar science. The presentation begins with a brief overview
describing what meteorites are and what they look like. Discussion
then continues with where meteorites come from, and how lunar
meteorites can be recognized from other meteorites. The presentation
then focuses on NASA's involvement with the U.S. Antarctic meteorite
program, and the curation of collected meteorites, including the tools
and materials used. Other locations where meteorites have been
collected, such as Africa, are also mentioned. The presentation
concludes with discussions about how the study of lunar meteorites has
contributed to the advancement of lunar science, including extending
the range of ages for the eruption of basaltic lavas, refining the
composition of the feldspathic highlands crust, and providing more
data to better understand the impact flux at Moon.
