(CNN) -- A robot ship's daring plunge toward an asteroid is documented in a series of images released this week by NASA, providing the closest look yet at the planetoid's ridged and warped terrain.
At the closest point the October 26 flyby, NEAR-Shoemaker flew within 5 miles (8 km) of the surface of Eros, an oddly shaped space rock that tumbles through space in an eccentric orbit.
The 90-second video zooms in closer than ever before on the dusty craters, boulder fields and mysterious grooves and ridges that riddle the asteroid, which is roughly twice the size of Manhattan.
"The resolution in these images is about three times better than
any we've seen of Eros," said Andrew Cheng, a NEAR (Near Earth
Asteroid Rendezvous) team scientist, in a statement. "There is an
amazing number and variety of boulders, some of which seem to
have a layered structure."
Mark Robinson, a NEAR science team member, said NEAR films are
scientifically as well as visually appealing.

"Setting the images in motion reveals a lot about the asteroid
itself," Robinson said. "The movies give us a
dynamic look at changes in the shadowing and shading of surface
features. By examining features with different illumination,
geologists get a better look into the history of the asteroid."
After its October plunge, NEAR-Shoemaker ascended
to an orbit of 124 miles (200 km).
The automobile-sized spacecraft will descend to a 22-mile (35-km)
orbit in December and is scheduled to conclude its mission in February.
