... ASTEROID’S MOONS : DISCOVERY BY RADAR . ... Moons of known asteroids have a low position ambiguity, which makes their discovery with powerful ground-based radar much easier than the discovery of new asteroids or other objects of Solar System. ... The other technique is a direct detection of radar echo from an asteroid moon. ... However, the diameter of a ground-based fully-steerable reflector is limited by 120-150 m to make it possible to perform two different functions: focusing and tracking (fig. ...

Next: Electronic database Up: A Database of Optical Previous: A Database of Optical . ... Many new observational data have been measured in the last years, e.g. by the Infrared Space Observatory in 1995-1998, and interpretation of these spectroscopic data is still in progress. This requires the comparison with data of ``analog materials'' delivered by spectroscopical laboratories. Various terrestrial analogs of cosmic solids have been studied in chemical and physical laboratories. ...

The Discovery of the Galilean Satellites . ... Probably the most significent contribution that Galileo Galilei made to science was the discovery of the four satellites around Jupiter that are now named in his honor. Galileo first observed the moons of Jupiter on January 7, 1610 through a homemade telescope. He originally thought he saw three stars near Jupiter, strung out in a line through the planet. ...
