The twin-Rover
mission to Mars is being commemorated by a handsome 5 oz. pure
silver proof medal. The NASA-approved designs were created by
Alex Shagin. The obverse features the two Rovers on the surface
of Mars, with a portion of our planetary system in the background;
the inscription reads "MARS EXPLORATION ROVERS · SPIRIT
· VI-10 · OPPORTUNITY · VII-7." The
reverse contains the NASA logo within a stylized sun; the surrounding
legend reads "UNITED STATES NATIONAL AERONAUTICS AND SPACE
ADMINISTRATION · 2003."
This is the
second issue in a series of NASA-approved commemoratives; the
first was a tribute to the Columbia crew. The Rover and Columbia
medals are available for $89 each from PandaAmerica, 3460 Torrance
Blvd., Suite 100, Torrance, CA 90503. Credit card orders can be
placed by calling (800) 472-6327 or e-mailing info@pandaamerica.com.
Add $5.50 for shipping and insurance per order. Each medal comes
with a Certificate of Authenticity.
Third-grader Sofi Collis won the Rover naming contest with the
following essay:
I used
to live in an Orphanage. It was dark and cold and lonely. At night,
I looked up at the sparkly sky and felt better. I dreamed I could
fly there. In America, I can make all my dreams come true
Thank-you for the "Spirit" and the "Opportunity."
"Opportunity"
was launched on July 7, 2003 and "Spirit" on
June 10. The twin spacecrafts in NASA's Mars Exploration Rover
project are carrying field-geology robots for arrival at Mars
in January. Both rovers will land in the Martian afternoon within
45 minutes of each other, while the Earth is still in view, allowing
the Earth to receive the landing signals.
Science instruments
on the Rovers are state-of-the-art tools that will acquire information
about the Martian environment. They include: Panoramic Camera,
Microscopic Imager, Miniature Thermal Emission Spectrometer, Rock
Abrasion Tool, and other instruments that will determine accurate
colors, brightness, and other information.
