Charles Kohlhase
artist, science educator, and lead designer of numerous planetary missions


Over the past few decades, tremendous advances have been made by the people at the Jet Propulsion Labratory in Pasadena, California, in the art and science of deep space navigation.  Using both radiometric and optical data types, the ability to estimate the approach flight path relative to Mars, for example, varies from about 1 km at one day before closest approach down to tens of metres a few hours out. This permits extremely accurate control for space craft destined to either orbit the red planet or complete a demanding entry, descent and landing sequence through its thin atmosphere.

Charles Kohlhase is an artist, science educator, and lead designer of numerous planetary missions, including the Voyager grand tour of the outer planets and beyond and the Cassini-Huygens mission to the Saturnian system
