The Multi-Spectral Imager is what Jessica and I were simulating. It will analyze the morphology and mineralogy of Eros at a high resolution -- about sixteen meters by ten meters (in the 100 kilometer orbit).
The Near-Infrared Spectrograph also gathers mineralogical data. Its resolution is lower than the MSI -- about 300 meters by 300 meters, at best.
The NEAR Laser Rangefinder has by far the highest resolution -- in can be as low as two meters by two meters, and on average is three and a half meters by three and a half meters. It gathers data about the topology of Eros.
