NEAR Science Instruments

Multi-Spectral Imager = MSI
	Images Eros in multiple spectral bands to determine its shape and surface features, and to map mineral distributions.
NEAR Infrared Spectrometer = NIS
	Measures the near-infrared spectrum to determine the distribution and abundance of surface minerals like olivine and pyroxene.
NEAR Laser Rangefinder = NLR
	A laser altimeter that measures the range to the surface to build up high resolution topographic profiles. This data will give a global shape model of Eros.
X-ray/Gamma-Ray Spectrometer = XGRS
	The X-Ray Spectrometer detects X-ray fluorescence from elements on the asteroid surface excited by solar X-rays. The Gamma-Ray Spectrometer detects gamma rays from specific elements on the surface. Some of the emissions are excited by cosmic rays and some are from natural radioactivity in the asteroid.
Magnetometer = MAG
	Searches for and maps any intrinsic magnetic field around Eros.
Radio Science
	A coherent X-band transponder measures radial velocities of the spacecraft relative to Earth. This helps to map the gravitational field of Eros.
