 Asteroid Gaspra
Gaspra was just another small asteroid that was given very little attention until it was discovered that the trajectory of the Galileo spacecraft would take it close to Gaspra.
Gaspra was found to have an elongated shape with a rotational period of 7.04 hours.
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.

  Images Of Asteroid Gaspra
This montage of 11 images taken by the Galileo spacecraft as it flew by the asteroid Gaspra on October 29, 1991, shows Gaspra growing progressively larger in the field of view of Galileo's solid-state imaging camera as the spacecraft approached 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.
Gaspra's very irregular shape suggests that the asteroid was derived from a larger body by nearly catastrophic collisions.

 Gaspra   (Site not responding. Last check: )
Gaspra was imaged by the Galileo spacecraft and found to have an elongated shape with a rotational period of 7.04 hours.
Gaspra is classified as an S-type asteroid and is likely composed of metal-rich silicates and perhaps blocks of pure metal.
The fact that Gaspra is irregular in shape and lacks any large craters suggests that it has a comparatively recent origin, most likely from the collisional breakup of a larger body.

This picture of asteroid 951 Gaspra is a combination of the highest-resolution morphology and color information obtained by the Galileo spacecraft during its approach to the asteroid on October 29, 1991.
The base image is the best fl-and-white view of Gaspra (resolution 54 meters/pixel) on which are superimposed the subtle color variations constructed from violet, green, and near-infrared (1000 nanometers) inages taken in an earlier sequence at a resolution about 164 meters/pixel.
Gaspra is an irregular body with dimensions about 19 x 12 x 11 kilometers (12 x 7.5 x 7 miles).

951 Gaspra (asteroid 951) is an S-type asteroid that orbits in the inner edge of the asteroid belt.
Gaspra was discovered by Grigoriy N. Neujamin in 1916.

This montage of 11 images taken by the Galileo spacecraft as it flew by the asteroid Gaspra on October 29, 1991, shows Gaspra growing progressively larger in the field of view of Galileo's solid-state imaging camera as the spacecraft approached 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.
Evidently, Gaspra lacks the large craters common on the surfaces of many planetary satellites, consistent with Gaspra's comparatively recent origin from the collisional breakup of a larger body.

 [No title]
This history may not be unusual for asteroids like Gaspra, many of which are believed to have accreted into relatively substantial minor planets during the formation of the solar system, only to be broken down in collisions over the ensuing billions of years.
Ida, like Gaspra, is an S‑type asteroid, meaning that it is a reddish object composed of a mixture of the minerals pyroxene, olivine, and iron.
The asteroid 951 Gaspra (inset) image is a mosaic of two images taken by Galileo from a range of 5,300 km some 10 minutes before closest approach, on October 29, 1991.

 Gaspra - True and Enhanced Color
The subtle variations in color may be due to slight differences in rock composition or to differences in the texture of the surface layer.
These possibilities should be resolved once the rest of Galileo's Gaspra data are played back in 1992.
Gaspra is about 19 by 12 by 11 kilometers (12 by 7.4 by 7 miles) and irregular in shape.
