Spacecraft Screen Saver displays spectacular images of interplanetary probes, space stations, satellites, and the space shuttle.

It includes 28 images displayed as a slide show. A title and description accompany each picture, and add educational value.

Some of the images are actual photographs while others are digital artist conceptions.

Options let you choose the time delay between images (in seconds or minutes), select which transition effects to use, and stretch the images to fit the screen.
