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.
Launched in 2007, NASA’s Dawn spacecraft is preparing for its encounter with dwarf planet Ceres, imaging the body from a distance of 740,000 miles as a final calibration of the probe’s science camera. Dawn will be captured into Ceres’ orbit in March 2015.
