    Rosetta measures comet's temperature

    The first temperature measurements of comet 67P/Churyumov-Gerasimenko were made when Rosetta closed in from 14000 km to the comet to just over 5000 km. The observations were made by the spacecraft's visible, infrared and thermal imaging spectrometer, VIRTIS, and revealed an average surface temperature of -70ºC. This implies the surface is predominantly covered in dust rather than ice, which would yield a lower temperature. The finding does not exclude localised patches of ice. The observations were made when the comet was ~553.5 million km from the Sun.

    Rosetta closed in from 3000 km to the comet to just 1327 km.

    Damn that's cool!!! what's going to be interesting over the next year is as the comet approaches sun and the tail starts activating, and Rosetta is in the plume.

    And in 2016 they send another probe to Bennu asteroid (which is even more exciting). It'll get there before 2019. But this time it's not one way trip. The probe will return to Earth with samples!

    Back on topic: new closeup pics of the surface

    Offtopic:

    In the meanwhile New Horizons spacecraft took pictures of Pluto and Charon orbiting each other


    [​IMG]


    Pluto and Charon are seen circling a central gravitational point known as the barycenter, which accounts for the wobbling motion. Since Charon is 1/12th the mass of Pluto the center of mass between the two actually lies a bit outside Pluto’s radius, making their little gravitational “dance” readily apparent.
