Asteroid's aging craters
JHU/APL PHOTO RELEASE
Posted: April 9, 2000
This NEAR Shoemaker image of the tip of the asteroid, taken March 6, 2000, from a range of 201 kilometers (125 miles), shows craters with a variety of shapes and sizes. When small craters first form, they typically have sharp rims and round floors. As they age, progressively smaller craters are superimposed, rounding the rims and pitting the walls and floors until the original underlying crater becomes almost unrecognizable.
Built and managed by The Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland, NEAR-Shoemaker was the first spacecraft launched in NASA's Discovery Program of low-cost, small-scale planetary missions. See the NEAR web site for more details.
