The Galilean Satellites [PDF]

Science, 1999
NASA's Galileo mission to Jupiter and improved Earth-based observing capabilities have allowed major advances in our understanding of Jupiter's moons Io, Europa, Ganymede, and Callisto over the past few years. Particularly exciting findings include the evidence for internal liquid water oceans in Callisto and Europa, detection of a strong intrinsic ...

Satellite-to-Satellite Data Transfer and Control.

7th Communications Satellite Systems Conference, 1977
Abstract : The LES-8 and -9 satellites are three-axis stabilized earth-orbit spacecraft which provide communications at UHF and K-band frequencies with the capability of simultaneously establishing and automatically maintaining a K-band (36-38 GHz) satellite-to-satellite data link. The inter-satellite data crosslink extends the earth coverage over that
