Eros is unique. Its cratering characteristics and statistics are unlike any other body in the Solar System. Even yours truly located on the more remote parts of the asteroid from the centre of mass, could just run off the surface into space. The complicated interaction between the variable surface gravity and centrifugal forces due to the relatively rapid rotation, mean that the effective gravitational vectors are very unusual. The craters look very eroded, with many seeming to have the floors filled in with dust, and there are many extremely large boulders, some as large as houses, scattered about the surface.
Many craters seem to have slumped at the edges exposing bright reflective material.
Explaining these unusual features will keep an array of scientists busy for years. In orbit for about a year, and running low on fuel due to the excessive manoeuvring required to get into orbit in the first place, a spectacular end game was developed. The mission scientists decided to try and land on Eros, even though NEAR was never designed for such an event. The last image snapped at a height of only 100m or so, and showing surface details only cm in dimension, was cut off about half way through, the main antenna tilting away from Earth at the moment of landing. Subsequent communication through the low gain antenna, allowed continued communication with the X ray and Gamma ray Spectrometer, and hopefully, improved surface composition data.
