NASA's Lunar Prospector Completed
News story originally written on March 12, 1997
The construction of NASA's Lunar Prospector has been completed. This
spacecraft will travel to the Moon in September 1997 to make the first complete
compositional and gravity maps of the Moon.
The Lunar Prospector's mission will be a profound one. Over 75% of the Moon's
surface is not mapped out in detail. In addition, there are several mysteries
about the Moon's composition and internal processes. The Lunar Prospector will
provide information about all of these inconsistencies by mapping out the lunar
surface composition, and gravity/magnetic fields. In addition, the craft will
try to detect any kind of volatile activity on the Moon, and detect whether or
not the Moon's poles contain water ice.
The Lunar Prospector's mission is expected to last one year, and will have a
polar orbit about the Moon. The craft has a mass of 660 pounds, and is 4.5 feet
high by 4 feet in diameter. Solar cells have been added to the craft to provide
additional power. Five instruments are located on the spacecraft, including a
gamma-ray spectrometer, alpha particle detector, magnetometeer, electron
reflectomer, and a Doppler gravity detector.
Several tests of the newly built craft will take place over the next several
months. The craft will be tested for functional and environmental safeties.
The Lunar Prospector was built by Lockheed Martin Missiles and Space
Corporation. The cost of the craft and its mission are estimated to $63
