NEAR Shoemaker
The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of planetary scientist
Eugene M. Shoemaker, is a
robotic space probe designed to study the
near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objective of NEAR was to return data on the bulk properties, composition,
mineralogy, morphology, internal
mass distribution and
magnetic field of Eros. Secondary objectives include studies of
regolith properties, interactions with the
solar wind, possible current activity as indicated by dust or gas, and the asteroid spin state. This data will be used to help understand the characteristics of
asteroids in general, their relationship to
meteorites and
comets, and the conditions in the early solar system. To accomplish these goals, the spacecraft was equipped with an
X-ray/
gamma ray spectrometer, a near-infrared imaging spectrograph, a multi-spectral camera fitted with a
CCD imaging detector, a
laser rangefinder, and a
magnetometer. A radio science experiment was also performed using the NEAR tracking system to estimate the
gravity field of the asteroid. The total mass of the instruments was 56 kg, and they required 81 W power.
