The MARS Globe 20x - Raised Relief Globe

Data obtained from the National Space Science Data Center has been utilized to create this magnificent Mars replica.  Elevations were calculated from the Mars Orbiter Laser Altimeter (MOLA) database, which recorded 600 million data points as the Mars Global Surveyor (MGS) spacecraft orbited the planet.  Mountain heights are exaggerated by 20 times in this first-of-its-kind, extreme raised-relief globe of Mars. 

A digital globe, so-called because it is created by laser beams hitting liquid plastic, under digital control of a computer that is following digital instructions that give a mathematically correct exaggeration for the plastic mountains.  The quantization of the plastic construction is visible as triangles, rectangles and trapezoids.

The 18 inch Mars Globe 20x has raised relief for the mountains. The mountain heights are exaggerated by 20 times. Each globe features over a million elevation points.

The globes are made from discrete layers of plastic that are laid down on top of each other using 200 layers per inch. The 18 inch globes use about 3600 layers.

The Mars 20x Globe comes with custom display stand and proprietary crating.

    <p><b><i><font size=On November 7, 1996, NASA successfully launched The Mars Global Surveyor (MGS) Mission.  The mission was intended to recover most of the science objectives of the ill-fated Mars Observer Mission, which was lost three days before it was to enter Mars orbit in August, 1993.  Included in the MGS instrument payload was the Mars Orbiter Laser Altimeter (MOLA).  The objective of the MOLA investigation was to globally map the topography of Mars at a resolution to permit global and regional scale scientific analyses as well as to aid in the future targeting of surface landers.  The Mars Global Surveyor successfully inserted into orbit around Mars on September 11, 1997.  Over the Fall of 1997, MOLA collected eighteen 20-minute topographic profiles of the northern hemisphere of Mars.  More data was collected during the Spring and Summer of 1998.  MOLA stopped collecting data at the end of July, 1998. The MGS continued with its mapping mission, observing the planet almost continuously through January, 2001.  MGS is now on its extended mission, which NASA has approved through September, 2004.  The MOLA oscillator stopped functioning on June 30, 2001 but MOLA continues to collect data in a passive radiometry mode.
