The Mineral Moon -this mosaic of 53 images was recorded by the Jupiter-bound Galileo spacecraft as it passed near our own large natural satellite in 1992. The pictures were recorded through three spectral filters and combined in an exaggerated false-color scheme to explore the composition of the lunar surface as changes in mineral content produce subtle color differences in reflected light.
Call me crazy but... If technology gets to the point where Space Shuttle flights are as common as airplane flights, I will be the first to buy a ticket just to see the Earth from space and experience zero gravity.
Voyager 2 image of Jupiter's moon Calisto. This image was taken from over 2 million km away as the spacecraft approached Jupiter. The bright spots peppering the surface are meteorite impact craters which have excavated through the dark surface and exposed the lighter material below. Callisto is 4,800 km in diameter
