A monitor at the European Space Agency's ESOC mission control center shows the static received by the ground station a moment after Rosetta's radio signal disappeared at 13:19 CEST Friday. The loss of contact marked the end of operations, a bittersweet moment.

Rosetta’s OSIRIS wide-angle camera captured this image of Comet 67P/Churyumov-Gerasimenko from an altitude of about 15.5 km above the surface during the spacecraft’s final descent on Friday.

Rosetta’s OSIRIS narrow-angle camera captured this image of Comet 67P/Churyumov-Gerasimenko at 10:14 GMT from an altitude of about 1.2 km during the spacecraft’s final descent on Friday.

This image captured by Rosetta’s OSIRIS narrow-angle camera shows Comet 67P/Churyumov-Gerasimenko from an altitude of about 5.7 km during the spacecraft’s final descent on Friday.

The soft focus of this photo can be forgiven because it's probably Rosetta's last image of Comet 67P/Churyumov-Gerasimenko, taken shortly before impact, at an estimated altitude of 51 m above the surface. The image was taken with the OSIRIS wide-angle camera Friday.
