How much data is in a single LORRI image? (LORRI, which stands for Long Range Reconnaissance Imager, is New Horizons' highest-resolution camera.) LORRI's detector is 1024 pixels square. Like many modern space cameras, when the camera reads out its detector, it digitizes each pixel as a 12-bit number. Twelve million is an awful lot of bits, but fortunately LORRI's images are amenable to lossless compression, especially now when they contain mostly black space; they can be zipped up to about 2.5 Megabits without any loss of detail. They can be made even smaller with lossy JPEG compression, but for optical navigation, precision counts; the pictures have to be returned losslessly.
