High Resolution Images From New Horizons Flyby Past Pluto


Summary: High resolution images emerge from the New Horizons flyby past Pluto Tuesday, July 14, 2015, according to NASA releases Friday, Dec. 4.

The New Horizons flyby past Pluto July 14, 2015, accounts for close-up, high-resolution, surface-detailed images of the solar system’s other red planet in National Aeronautics and Space Administration releases Dec. 4, 2015.
Surface details benefit from New Horizons’ closest approach of 10,000 miles (17,000 kilometers) from Pluto and the ice dwarf’s Charon, Hydra, Kerberos, Nix and Styx moons. Sharpness comes from technologies unlike Gold cameras pointing and shooting close-up, 7- by 8-centimeter (2.8- by 3-inch), 3-D-stereo lunar segments during Apollo 11, 12 and 14. The unusual observing mode draws upon two of New Horizons’ seven instruments investigating atmospheres, composition, geology and surfaces of the Kuiper belt and the Pluto system.
The mode ensures non-blurriness through short exposures.

LORRI, the long range reconnaissance imager, fulfills responsibilities as the grand piano-sized spacecraft’s telescopic camera charged with far-side maps, high-resolution geologic data and long-distance encounter data. The MVIC infrared spectrometer and visible imager generate color, composition and thermal maps for Ralph, Multispectral Visual Imaging Camera and Pluto Exploration Remote Sensing Investigation instrument. The coordination heightens resolutions to five times that of the best images of Triton, Neptune’s largest moon, Aug. 25, 1989, by the Voyager 2 space probe.
The resolution is six times New Horizons’ global map of resolved surface images at pixel resolutions of 24 miles (40 kilometers) to 1,250 feet (400 meters).
The images juggle LORRI’s snapping pictures every three seconds with Ralph’s scanning surfaces.
Pictorial sequences knit together a 50-mile- (80-kilometer-) wide strip of icy geological features at resolutions of 250 to 280 feet (77 to 85 meters) per pixel.
Revelations of features sized less than half one city block link the informally named al-Idrisi mountains and Sputnik Planum with the rubbly material of crumpled ridges. New Horizons principal investigator Alan Stern of the Southwest Research Institute in Boulder, Colorado, mentions: “The science we can do with these images is simply unbelievable.” Geology, Geophysics and Imaging deputy lead William McKinnon of Washington University in St. Louis, Missouri, notes: “Looking into Pluto’s depths is looking back into geologic time.”
The sequence offers the latest data transmitted weekly from New Horizons’ digital recorders.

Icy, rugged plains full of craters with interior, layered walls prompt Dr. McKinnon’s describing impact craters as “nature’s drill rigs” critical to reconstructing Pluto’s geological history.
The sculptured deposition, erosion, faulting and tumbling of craters, mountains, plains, ridges and shorelines qualify Pluto’s surface geography for the NASA description of a badlands-reminiscent topography.  The meeting place of the ice dwarf planet’s mountains, ridges and shorelines remains one of the most potentially informative of Pluto’s past and present geological processes. John Spencer of the Southwest Research Institute says: “[M]ountains are huge ice blocks that have been jostled and tumbled and somehow transported to their present locations.”
New Horizons flyby past Pluto weeklies tell NASA the ice dwarf's darkest secrets.
