NASA scientist Nikolaos Paschalidis, who recreated five instrument-enabling microchips for one of the instruments flying on the New Horizons mission, has waited nearly 10 years for the mission to reach its destination.

Pluto ‘Wows’ in Spectacular New Backlit Panorama

The craft's miniature cameras, radio science experiment, ultraviolet and infrared spectrometers and space plasma experiments will characterize the global geology and geomorphology of Pluto and Charon, map their surface compositions and temperatures, and examine Pluto's atmosphere in detail. The spacecraft's most prominent design feature is a nearly 7-foot (2.1-meter) dish antenna, through which it will communicate with Earth from as far as 4.7 billion miles (7.5 billion kilometers) away.
