PIA09234: Animation New Horizons Sees Pluto (2006)
Date: 21 Sep 2006

The Long Range Reconnaissance Imager (LORRI) on New Horizons acquired images of the Pluto field three days apart in late September 2006, in order to see Pluto's motion against a dense background of stars. LORRI took three frames at 1-second exposures on both 21 Sept. and 24 Sept. Because it moved along its predicted path, Pluto was detected in all six images.


These images are displayed using false-color to represent different intensities: the lowest intensity level is black, different shades of red mark intermediate intensities, and the highest intensity is white.


The images appear pixilated because they were obtained in a mode that compensates for the drift in spacecraft pointing over long exposure times. LORRI also made these observations before operators uploaded new flight-control software in October of that year; the upgraded software package includes an optical navigation capability that will make LORRI approximately three times more sensitive than for these Pluto observations.
