Panela: possible area for the collision event overlaid on the digital terrain model (SHAP7) and the estimated trajectory (constrained by red lines, direction indicated by white arrow) from first touchdown, including the position of Philae in flight as seen in OSIRIS camera images. Panel b: possible area for second touchdown overlaid on an OSIRIS image. The incoming flight direction is indicated by a red arrow. Philae is visible to the right at its final locations (circled).
