Ida: Limb at Closest Approach
This image is one frame of a mosaic of 15 frames shuttered near Galileo's closest approach to Ida. Since the exact location of Ida in space was not well known prior to the Galileo flyby, this mosaic was estimated to have only about a 50 percent chance of capturing Ida. Fortunately, this single frame did successfully image a part of the sunlit side of Ida.
The area seen in this frame shows some of the same territory seen in a slightly lower resolution fulldisk mosaic of Ida returned from the spacecraft in September, 1993, but from a different perspective.
Prominent in this view is a 2 kilometer-deep 'valley' seen in profile on the limb. This limb profile and the stereoscopic effect between this image and the fulldisk mosaic will permit detailed refinement of Ida's shape in this region.
This high resolution view shows many small craters and some grooves on the surface of Ida, which give clues to understanding the history of this heavily impacted object.

system in 1995-97, is managed for NASA's Office of Space Science by the Jet
