[2][3] LORRI is a reflecting telescope of Ritchey-Chrétien design, and it has a main mirror diameter of 208 mm (8.2 inches) across.
[4] LORRI is a telescopic panchromatic camera integrated with the New Horizons spacecraft, and it is one of seven major science instruments on the probe.
[7] In 2018, New Horizons spacecraft used navigation data from LORRI for its planned flyby of Arrokoth in a couple months.
[12] In December 2017, LORRI took an image at a greater distance from Earth than Pale Blue Dot by Voyager 1, in this case of the Wishing Well Cluster.
[13] This cluster was also the first light image for the Wide Field and Planetary Camera of the Hubble Space Telescope, taken in May 1990.
[15] A large stack of images of Arrokoth from August to December 2018 was used to confirm a closer flyby, rather than more distant by ruling out moons and rings systems to a certain level of detection.
[4] Specifications:[5][4] The mirror is made of silicon carbide which helped support meeting the thermal requirements of the design.
[20] The instrument is a thinned backside-illuminated charge-coupled device, and captures images at a resolution of 1024 by 1024 pixels, with a variety of exposure settings.
