Image credit: NASA/JHUAPL/SwRI.New Horizons scientists made this false colour image of Pluto using a technique called principal component analysis to highlight the many subtle colour differences between Pluto’s distinct regions. The image data were collected by the spacecraft’s Ralph/MVIC colour camera on 14 July at 11:11 UTC, from a range of 22,000 miles (35,000 kilometres). This image was presented by Will Grundy of the New Horizons’ surface composition team on 9 November at the Division for Planetary Sciences (DPS) meeting of the American Astronomical Society (AAS) in National Harbor, Maryland.
NASA’s New Horizons spacecraft fine-tuned its path toward Pluto on Tuesday, firing its rocket thrusters for 93 seconds to aim for a fleeting flyby of the distant dwarf planet July 14.
Backlit by the Sun, Pluto’s atmosphere rings its silhouette like a luminous halo in this image taken by NASA’s New Horizons spacecraft on July 15. This global portrait of the atmosphere was captured when the spacecraft was about 1.25 million miles (2 million kilometres) from the dwarf planet.
Pluto’s day is 6.4 Earth days long. The dwarf planet’s largest moon, Charon, also rotates once every 6.4 days as the two worlds are tidally locked to each another. This sequence of images from the Long Range Reconnaissance Imager (LORRI) and the Ralph/Multispectral Visible Imaging Camera on NASA’s New Horizons spacecraft shows us full rotations of the two bodies.
