This image released 13 February 2000 by NASA just in time for its Valentine's Day date with 433 Eros, the Near Earth Asteroid Rendezvous (NEAR) spacecraft snapped this photo during its approach to the 21-mile-long space rock. Taken 11 February 2000 from 1,609 miles (2,590 kilometers), the picture reveals a heart-shaped depression about 3 miles (5 kilometers) long. Scientists at the Johns Hopkins University Applied Physics Laboratory -- which manages the NASA mission -- processed the image 12 February 2000. Photos taken from closer during the next few days will help the NEAR team unravel the mystery of this shadowy feature.
