Ralph

Ralph is a digital imager set to fly on NASA's New Horizons mission to Pluto and the Kuiper Belt. It must be able to take sharp images in sunlight levels 1,000 times fainter than what we see on Earth.
Ralph consists of three panchromatic (black-and-white) and four color imagers inside its Multispectral Visible Imaging Component (MVIC), as well as an infrared compositional mapping spectrometer called the Linear Etalon Imaging Spectral Array (LEISA). Ralph's suite of seven detectors - all charge-coupled devices (CCDs), as you'd find in a digital camera - are fed by a single, sensitive magnifying telescope with a resolution more than 10 times better than the eye can see.
The entire package weighs 11 kilograms (about 24 pounds) and draws 6 watts of power.
