Ganymede: Radar Surface Characteristics
Science, 1980Radar observations of Ganymede, at X-band, show that the surface is unusually bright and has unusual polarization properties. A model of the surface based on large numbers of random ice facets (hence vacuum-ice interfaces) is able to account for these characteristics.

Ganymede: Observations by Radar
Science, 1975Radar cross-section measurements indicate that Ganymede scatters to Earth 12 percent of the power expected from a conducting sphere of the same size and distance. This compares with 8 percent for Mars, 12 percent for Venus, 6 percent for Mercury, and about 8 percent for the asteroid Toro.

Detection of Ozone on Ganymede
Science, 1996An absorption band at 260 nanometers on the trailing hemisphere of Ganymede, identified as the Hartley band of ozone (O 3 ), was measured with the Hubble Space Telescope. The column abundance of ozone, 4.5 × 10 16 per square centimeter, can be produced by ion impacts or by photochemical ...

ABSTRACTSchubert's songGanymedhas attracted a great deal of interest from analysts on account of its progressive tonal plan, which is often seen as a challenge to Schenkerian theories of tonal structure, as well as its evocative text. This article draws upon a spatial theory of tonal meaning which helps both to resolve the epistemological impasse faced

JUICE, JUpiter ICy moons Explorer, the ESA mission planned to be launched in 2022 and to arrive at Jupiter in 2029, will make detailed observations of Jupiter and three of its largest moons. One of its goals is to improve the current estimates of Ganymede surface age [2].Ganymede was observed firstly by Voyager 1 and 2 in 1979, and then by Galileo ...
