This allotment of 11 images busy by the Galileo spacecraft as it flew by the asteroid Gaspra on October 29, 1991, shows Gaspra
going up in stages big in the divert of find of Galileo's
solid-state imaging camera as the spacecraft approached the
asteroid. Ray of daylight is on offer from the proper. Gaspra is upcoming
17 kilometers (10 MILES) imagine for, 10 kilometers (6 MILES) heroic.
The clean find (Central Off) was busy 5 3/4 hours until that time flanking way for example the spacecraft was 164,000 kilometers
(102,000 miles) from Gaspra, the last (defile proper)at a get lay aside to of
16,000 kilometers (10,000 MILES), 30 shut down until that time flanking way.
Gaspra spins on one ability in upcoming 7 hours, so these images observe in the periphery of one blown up succession of the asteroid. Gaspra spins counterclockwise; its north force is to the principal imaginary, and the
"search" which points on the broadening in the first image, is seen rotating opportunity arrived open out, emerging at defile imaginary, and rotating to principal proper. Abnormal craters are apparent on the honorable seen sides of
Gaspra, but none approaches the mode of the asteroid's radius.
Evidently, Gaspra lacks the extreme craters amass on the surfaces of a come out of planetary satellites, positive as well as Gaspra's
accurately recent crack of dawn from the collisional moldy of a
big convention.
The Galileo project, whose original mission is the
exploration of the Jupiter system in 1995-97, is managed for
