[edit] Summary

Description

A montage of images taken by the Galileo spacecraft as it flew by the asteroid Gaspra on October 29, 1991. It shows Gaspra growing progressively larger in the field of view of Galileo's solid-state imaging camera as the spacecraft approached the asteroid. Sunlight is coming from the right. The earliest view (upper left) was taken 5 3/4 hours before closest approach when the spacecraft was 164,000 kilometers (102,000 miles) from Gaspra, the last (lower right) at a range of 16,000 kilometers (10,000 miles), 30 minutes before closest approach. Gaspra spins once in roughly 7 hours, so these images capture almost one full rotation of the asteroid. Gaspra spins counterclockwise; its north pole is to the upper left, and the "nose" which points upward in the first image, is seen rotating back into shadow, emerging at lower left, and rotating to upper right.
