What are some of the instruments carried by the New Horizons spacecraft?

New Horizons has seven scientific instruments onboard, one of which (the Student Dust Counter) was built and will be operated by students as the spacecraft travels across the solar system. There is also REX, the Radio Science Experiment; SWAP, which will measure the Solar Wind Around Pluto; PEPSSI, the Pluto Energetic Particle Spectrometer Science Investigation; LORRI, the Long Range Reconnaissance Imager; and a pair of imaging spectrographs.
