Raised Relief Mars Globe Brings the Red Planet Closer

Originating Technology/NASA Contribution
When the Mars
Reconnaissance Orbiter (MRO) entered the
Red Planet’s atmosphere in March 2006, it joined the
ranks of other noble explorers studying the planet over
the past 2,000-plus years. This new NASA orbiter will
study the Martian atmosphere and surface, and probe underground
in search of past and present water, making it one of
the most advanced studies of the planet to date. People
have been aware of the existence of Mars and in awe of
its presence for centuries, ever since early humans noticed
that it did not shimmer like the surrounding stars.

The
face on Mars, actually just a series of craters
and hills that, when viewed from a distance, look
like the features of a human face, fueled speculation
for years that the Red Planet housed some form
of life and that Martians were trying to communicate
with Earthlings. |
The Babylonians, around 400 BCE, called the planet Nergal
after their god of war. Around this same time, the Ancient
Egyptians, also gazing upward, noticed the planet and
named it “Har Decher,” the Red One. The Greeks called
the planet Ares after their swaggering, blood-thirsty
god of war. The Romans named the fourth planet from the
Sun “Mars” after their mythological god of war.
Whatever the name, the Red Planet has forever captured
people’s imaginations. With its blood-red, rocky surface,
and its pronounced visibility, Mars has sparked the imaginations
of people for generations, and speculations that there
is life on the surface have never ceased. There is even
a topographical feature that makes it look as if there
is a face on the planet, which many have taken as a sign
that the “people” of Mars are trying to communicate with
Earth. Beliefs that other beings live on Mars have been
so rampant that the term “Martian,” meaning from Mars,
is now synonymous with space alien.
For example, since 1948, when he was first introduced
to audiences, the Warner Bros. animated character Marvin
the Martian has been attempting to blow up the Earth
with his Illudium Q-36 Explosive Space Modulator, since
our Blue Planet blocks his view of Venus.
And then, there is always the classic CBS television
science fiction comedy that ran from 1963 to 1966, “My
Favorite Martian,” in which the lovable Uncle Martin,
an English-speaking Martian, appears very human—despite
retractable antennae and the abilities to move objects
with the point of a finger, turn invisible at will, and
send telepathic messages.
It has not always been fun and hijinks coming down from
the seventh largest planet in the solar system, though.
People have been afraid of Mars and its “Martians.” The
most famous example of this fear dates back to October
31, 1938, when nearly 2 million Americans sat down to
their evening’s entertainment of news and a musical score,
and were scared out of their wits when a young radio
personality, Orson Wells, interrupted their scheduled
programming with a news-style drama that convinced many
that Earth was being invaded by Martians. The radio play
was Orson Wells’ adaptation of H.G Wells’ “War of the
Worlds,” updated and set in present day (1930s) United
States, as opposed to Victorian England.
It began with a meteor strike, followed by a burst of
incandescent gas, and the next thing listeners knew,
the Martians had landed in rural New Jersey and were
beating a devastating path toward New York City. Despite
having pre-warned the audiences that the story was a
dramatic presentation, the show still caused mass pandemonium.
Decades later, NASA determined to discover if there is
or ever was life on Mars.

In the 1960s, the Mariner 4, an unmanned flyby spacecraft,
gave scientists their first glimpse of Mars at close
range, finally putting to rest the myths that the Red
Planet may have harbored an advanced civilization. Mariner
4 cruised for 228 days before it reached Mars, passing
at an altitude of 9,846 kilometers from the planet’s
surface. An onboard television camera recorded 21 images
of the surface, bringing to Earth the first close-up
pictures of Mars.
Mariners 6 and 7 were designed to fly over the equator
and southern hemisphere of Mars. Geologic features—including
cratered deserts, huge concentrically terraced impact
regions, collapsed ridges, and craterless depressions—were
among the Mariners’ many revelations.
In 1971, Mariner 9 became the first spacecraft to orbit
another planet. The spacecraft circled Mars twice daily
for a full year, photographing the surface and analyzing
the atmosphere with infrared and ultraviolet instruments.
When Mariner 9 first arrived, Mars was almost totally
obscured by dust storms, which persisted for a month.
After the dust cleared, Mariner 9 revealed the true surface
of Mars, with gigantic volcanoes and a canyon stretching
3,000 miles across its surface.
In 1976, the Viking
Mission inserted two probes into
the planet’s atmosphere. The Viking probes each consisted
of two primary pieces, a lander and an orbiter. The Viking
landers separated from the orbiters upon arrival, and
then descended onto the Martian surface, each at a different
location. Among some of the orbiter’s discoveries were
that Mars had numerous features of geologic interest.
Mars Global Surveyor became the first successful mission
to the Red Planet in 2 decades when it launched November
7, 1996, and entered orbit on September 12, 1997. After
a year and a half trimming its orbit from a looping ellipse
to a circular track around the planet, the spacecraft
began its prime mapping mission in March 1999. The mission
has, with its primary instrument, the Mars Orbiter Laser
Altimeter (MOLA), studied the entire Martian surface,
atmosphere, and interior, and has returned more data
than all previous Mars missions combined.
This same year, Mars
Pathfinder landed on the planet’s
surface and managed to collect and transmit 2.3 billion
bits of information, including more than 16,500 images
from the lander and 550 images from the rover, Sojourner,
as well as more than 15 chemical analyses of rocks and
soil and extensive data on winds and other weather factors.

The
Relief Globe Company creates raised relief globes
using the most up-to-date information available,
exaggerated to bring out the unique characteristics.

Currently, as part of the Mars
Exploration Rover program,
Spirit and Opportunity have been roving about the Martian
landscape for years beyond their expected survival dates,
exploring the surface and sending pictures back to Earth.
The robot geologists landed on the rocky surface in 2003
with an expected lifespan of 90 days, but continue to
this day to crest hills and scoot through the valleys
of the dusty, red terrain.
NASA has brought people closer to the surface of this
fascinating planet and it even intends to send people
to explore its surface; but people have never really
been able to see Mars up close or touch its surface—until
now. Thanks to a clever use of NASA geographical data,
in the form of a super-accurate globe, it now takes just
a matter of seconds to orbit Mars—a far cry shorter than
the 2 years it normally takes for a Martian year to pass.
Similarly, the surface can now be within arm’s reach
instead of the varying 35 to 250 million miles that must
otherwise be traversed.
Partnership
When Alan Folmsbee retired from his position at a computer
company in 2003, he had plenty of energy and some expendable
income with which he wanted to purchase a globe collection.
Not finding the quality or scope of globes that he had
hoped to purchase, Folmsbee founded The
Relief Globe Company, in Boulder Creek, California, to produce raised
relief globes based on specifications from actual databases.
While the average globe is smooth, its depictions miss
the opportunity to show topographical features. It denies
the ability of the globe to show features and details
in a 3-D display. The topographical maps create landmarks
not accessible with a map or a non-relief globe. A raised
relief globe, however, allows the mountains and canyons
to become real and tangible in ways that a cardboard
globe covered in numbers and letters just cannot.
He purchased databases online for ocean globes, as well
as those for the Moon, Venus, and Mars. The Mars data,
the complete recordings taken by the Mars Global Surveyor’s
MOLA instrument, filled 15 CD-ROMs. After trying to use
those CD-ROMs, he downloaded the more up-to-date data
from the NASA Planetary Data System archives maintained
by the Earth and Planetary Remote Sensing Laboratory
in the Department of Earth and Planetary Sciences at
the Washington University in St. Louis. Folmsbee then
used his computer background to write a program that
would take the data and run simulations—a process that
went remarkably smooth due to the large amount of detailed
data supplied him by MOLA. Within 2 weeks, Folmsbee had
a fully functional model of Mars, the first digitally
produced 3-D depiction of the planet ever created.
He then contacted Spectrum
3D, Inc., a state-of-the-art
prototyping, low-run, injection molding, and rapid-tooling
production company located in Tustin, California. Spectrum
3D had a history of making precision products from computer
designs—it made the robots for the Twentieth Century
Fox motion picture “I, Robot,” the futuristic adaptation
of Isaac Asimov’s novel by the same name, as well as
special effects for a handful of other major motion pictures
and independent films.
Spectrum 3D accepted the task of manufacturing the raised
relief Mars globe. The first step was to work with The
Relief Globe Company to determine which level of relief
was the most appealing. The 7-times exaggeration was
too bland, while the 40 times was, perhaps, too much,
though they did present several 40-times raised relief
Mars globes to the National Federation of the Blind to
share with blind students who would otherwise have no
idea what the surface of the Red Planet was like. The
National Federation of the Blind, working with NASA’s
Jet Propulsion Laboratory (JPL) to set up summer internships
in technical fields for blind students as part of NASA’s
Achieving Competence in Computing, Engineering, and Space
Science program, introduced the globe to JPL Mars education
and engineering staff who would be mentoring the students.
The JPL team met with Spectrum 3D and The Relief Globe
Company and provided guidance for their future models.
They suggested toning down the exaggeration, as they
felt that perhaps 20-times raised relief was more subtle,
yet still allowed the topographical features to stand
out. They also suggested a revised color scheme based
upon some imagery from the Viking Mission. The final
test, though, came when blind NASA interns at JPL were
able to identify the major topographical features of
the globe.
Product Outcome
The Mars Globe 20x is the first digitally produced raised
relief globe to be sold at retail establishments. The
rises and dips of the Martian landscape have been multiplied
by 20 to make the shapes more noticeable to human touch
and sight. They make this globe, with its over 1 million
elevation points, a visually stunning introduction to
the planet.
Spectrum 3D used the NASA digital land elevation data
to aim lasers that then shaped and defined the master
globe’s surface. Subsequent copies were then made by
creating a master globe mold. The molded copies are hand
finished by workers who remove errant edges or lines
that may appear on the raw globes and then paint the
surfaces. The result is a globe that measures in at 18
inches in diameter, roughly 1:15,729,473 scale of the
actual planet.

The exaggerated raised relief is like having a 3-D digital
microscope for planetary shapes. This makes the landmarks
easier to learn and understand, as it provides easy visuals
for orientation. People have a natural propensity for
understanding 3-D shapes more easily than numbers or
words. The 3-D globes appeal to both the kinetic and
visual learning aspects of the brain, making it easy
for people to readily memorize the landmarks and to make
a mental model that they will remember for a long time.
The polar caps on the north and south poles lend visual
contrast to the otherwise blanketing palette of reds
and browns, but the real excitement is in the richly
varying landscape. The globe helps show the landmarks
in relative sizes and positions. Olympus Mons, the highest
point on Mars, is 78,000 feet tall, 2.6 times taller
than Mount Everest. There are also 5 other giant volcanoes,
plus about 15 major volcanoes, that are each about the
entire size of Hawaii. It is a captivating, busy landscape.
On a topographical map, coloring tends to blur these
dramatic features—but not so on the raised relief globe.
A giant crack runs down one side of the planet. It is
half as deep as Olympus Mons is tall—29,000 feet. This
“Grand Canyon” runs the distance from what would be Los
Angeles to New York, here on Earth.
Most striking about the globe’s appearance, though, is
that Mars is not perfectly round. In fact, it appears
quite lopsided. On the side opposite the large volcano
clusters is a deep crater—the largest in the solar system.
This great depression, when viewed simultaneously with
the exaggerated mountains, gives the appearance that
something large struck the planet, creating the crater
and forcing the volcanoes out of the surface on the opposite
side. This striking feature was one of the elements that
the JPL staff members were so excited to see. They had
been studying the planet for years and this was the first
time they had ever had this perspective available to
them on a globe. Other globes of Mars had just been round
or showed the topography in such low scale that it was
hardly noticeable.
The Mars Globe 20x is being distributed in the United
States and throughout Europe. It has myriad uses, including
as an educational display in classrooms, museums, and
lobbies. It can serve just as well as a piece of art
with the ability to captivate and amaze the viewer just
as the early civilizations were amazed when they first
gazed up and started wondering about that red, glowing
orb.
