[meteorite-list] NASA to Release New Pluto Images, Science Findings at July 17 NASA TV Briefing
July 16, 2015 MEDIA ADVISORY M15-109 NASA to Release New Pluto Images, Science Findings at July 17 NASA TV Briefing [Image] This new image of an area on Pluto's largest moon Charon has a captivating feature -- a depression with a peak in the middle, shown here in the upper left corner of the inset. The image shows an area approximately 240 miles (390 kilometers) from top to bottom, including few visible craters. The image was taken at approximately 6:30 a.m. EDT on July 14, 2015, about 1.5 hours before closest approach to Pluto, from a range of 49,000 miles (79,000 kilometers). Credits: NASA-JHUAPL-SwRI NASA will hold a media briefing at 1 p.m. EDT Friday, July 17, to reveal new images of Pluto and discuss new science findings from Tuesday's historic flyby. The briefing will be held in James E. Webb Auditorium at NASA Headquarters, located at 300 E St. SW in Washington. NASA Television and the agency's website will carry the briefing live. Participants in the briefing will be: * Jim Green, director of Planetary Science at NASA Headquarters in Washington * Alan Stern, New Horizons principal investigator at Southwest Research Institute (SwRI) in Boulder, Colorado * Randy Gladstone, New Horizons co-investigator at SwRI in San Antonio * Jeffrey Moore, New Horizons co-investigator at NASA's Ames Research Center in Moffett Field, California * Fran Bagenal, New Horizons co-investigator, University of Colorado, Boulder Media may participate by phone. To join the briefing by phone, reporters must email their name, affiliation and telephone number to Karen Northon at karen.nort...@nasa.gov by noon Friday. Media and the public also may ask questions during the briefing on Twitter using the hashtag #askNASA.

[meteorite-list] From Mountains to Moons: Multiple Discoveries from NASA's New Horizons Pluto Mission
July 15, 2015 RELEASE 15-152 >From Mountains to Moons: Multiple Discoveries from NASA's New Horizons Pluto >Mission Icy mountains on Pluto and a new, crisp view of its largest moon, Charon, are among the several discoveries announced Wednesday by the NASA's New Horizons team, just one day after the spacecraft's first ever Pluto flyby. "Pluto New Horizons is a true mission of exploration showing us why basic scientific research is so important," said John Grunsfeld, associate administrator for NASA's Science Mission Directorate in Washington. "The mission has had nine years to build expectations about what we would see during closest approach to Pluto and Charon. Today, we get the first sampling of the scientific treasure collected during those critical moments, and I can tell you it dramatically surpasses those high expectations." "Home run!" said Alan Stern, principal investigator for New Horizons at the Southwest Research Institute (SwRI) in Boulder, Colorado. "New Horizons is returning amazing results already. The data look absolutely gorgeous, and Pluto and Charon are just mind blowing." A new close-up image of an equatorial region near the base of Pluto's bright heart-shaped feature shows a mountain range with peaks jutting as high as 11,000 feet (3,500 meters) above the surface of the icy body. The mountains on Pluto likely formed no more than 100 million years ago -- mere youngsters in a 4.56-billion-year-old solar system. This suggests the close-up region, which covers about one percent of Pluto's surface, may still be geologically active today. "This is one of the youngest surfaces we've ever seen in the solar system," said Jeff Moore of the New Horizons Geology, Geophysics and Imaging Team (GGI) at NASA's Ames Research Center in Moffett Field, California. Unlike the icy moons of giant planets, Pluto cannot be heated by gravitational interactions with a much larger planetary body. Some other process must be generating the mountainous landscape. "This may cause us to rethink what powers geological activity on many other icy worlds," says GGI deputy team leader John Spencer at SwRI. The new view of Charon reveals a youthful and varied terrain. Scientists are surprised by the apparent lack of craters. A swath of cliffs and troughs stretching about 600 miles (1,000 kilometers) suggests widespread fracturing of Charon's crust, likely the result of internal geological processes. The image also shows a canyon estimated to be 4 to 6 miles (7 to 9 kilometers) deep. In Charon's north polar region, the dark surface markings have a diffuse boundary, suggesting a thin deposit or stain on the surface. New Horizons also observed the smaller members of the Pluto system, which includes four other moons: Nix, Hydra, Styx and Kerberos. A new sneak-peak image of Hydra is the first to reveal its apparent irregular shape and its size, estimated to be about 27 by 20 miles (43 by 33 kilometers). The observations also indicate Hydra's surface is probably coated with water ice. Future images will reveal more clues about the formation of this and the other moon billions of years ago. Spectroscopic data from New Horizons' Ralph instruments reveal an abundance of methane ice, but with striking differences among regions across the frozen surface of Pluto. The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland designed, built and operates the New Horizons spacecraft and manages the mission for NASA's Science Mission Directorate. SwRI leads the mission, science team, payload operations and encounter science planning. New Horizons is part of NASA's New Frontiers Program, managed by the agency's Marshall Space Flight Center in Huntsville, Alabama.

Re: [meteorite-list] Charon
Hi all - I may be mistaken, but it looks to me like Charon was peppered with roughly 30 meter cometissimals like those perhaps responsible for the 5 kiloton air blasts that occurred at Rio Curaca and Rupunini in the last century.
