Project scientist Matt Taylor speaks about Rosetta’s final moments

The European Space Agency’s Rosetta spacecraft closed in Thursday for a deliberate crash landing on the surface of comet 67P/Churyumov-Gerasimenko on Friday, a slow-motion kamikaze plunge to bring the enormously successful mission to an end after more than two years of unprecedented close-range observations.

Data collected by NASA’s New Horizons probe and ESA’s Rosetta mission suggest Pluto might have formed from the accretion of a billion or so smaller bodies similar to Comet 67P/Churyumov-Gerasimenko and other Kuiper Belt objects.

Sifting through images from ESA’s Rosetta mission, researchers are learning more about the properties of comet 67P by studying where boulders fall and cliffs collapse.
