The European Space Agency has used data from both the Philae lander and Rosetta orbiter experiments, as well as simulation results based on Philae’s mechanical design to reconstruct the lander’s attitude and motion during its descent and touchdowns on Comet 67P/Churyumov-Gerasimenko on 12 November 2014.
The amazing achievement of putting a lander on a comet one year ago was the culmination of more than a decade’s chase through space.
