Abstract

Philae, a lander, is part of the Rosetta mission to investigate a comet. It is has been delivered to the surface of 67P/Churyumov-Gerasimenko in November 2014. This allowed the first in-situ measurements of a cometary surface. We report the precise circumstances of the landing and the bouncing of Philae. We used engineering data in conjunction with operational instrument data for reconstructing the bouncing trajectory and the rebound parameters. These data also provide information on the mechanical properties (strength, layering) of the comet surface. The first touch-down (TD1) site, Agilkia, appears to have a granular soft surface (1 kPacompressive strength) of at least ~20 cm possibly on top of a hard layer, while the final landing site, Abydos, shows a hard surface.
