Rosetta saw cliffs collapse on comet

The comet visited by the Rosetta spacecraft is constantly being re-shaped, sometimes in dramatic fashion.
It witnessed the collapse of entire cliffs at two locations on Comet 67P, events that were probably driven by exposure to sunlight.
The European probe documented the widespread breakdown of materials on the surface during nearly two years orbiting the 4km-wide body.

Rosetta's last words: science descending to a comet

ESA's Rosetta completed its incredible mission on 30 September, collecting unprecedented images and data right until the moment of contact with the comet's surface.
Rosetta's signal disappeared from screens at ESA's mission control at 11:19:37 GMT, confirming that the spacecraft had arrived on the surface of Comet 67P/Churyumov-Gerasimenko and switched off some 40 minutes earlier and 720 million kilometres from Earth.

Rosetta's last image

On Friday, Rosetta's historic mission concluded with the spacecraft descending to the surface of Comet 67P/Churyumov-Gerasimenko.
Rosetta was commanded to make a final series of unique scientific measurements very close to the comet, including taking images like this one, of its final resting place.
The Rosetta Stone was originally located in Sais, and we shall name the impact point as such so we can finally say that Rosetta has come home to Sais

Final Descent Image from Rosetta Spacecraft

A new image of comet 67P/Churyumov-Gerasimenko was taken by the European Space Agency's (ESA) Rosetta spacecraft shortly before its controlled impact into the comet's surface on Sept. 30, 2016. Confirmation of the end of the mission arrived at ESA's European Space Operations Center in Darmstadt, Germany, at 4:19 a.m. PDT (7:19 a.m. EDT / 1:19 p.m. CEST) with the loss of signal upon impact.

Rosetta mission ends in comet collision

Europe's Rosetta probe has ended its mission to Comet 67P by crash-landing on to the icy object's surface.
Mission control in Darmstadt, Germany, was able to confirm the impact had occurred when radio contact to the ageing spacecraft was lost abruptly.
The assumption is that the probe would have been damaged beyond use.

20 hours to go

The spacecraft is set to complete its historic mission in a controlled descent to the surface of comet 67P/C-G on 30 September, with the end of mission confirmation predicted to be within 20 minutes of 11:20 GMT (13:20 CEST).

NASA Television to Provide Coverage of European Mission Comet Touchdown

NASA Television and the agency's website will air the conclusion of ESA's (European Space Agency's) Rosetta mission from 6:15 to 8 a.m. EDT Friday, Sept. 30, with NASA commentary, interviews and analysis of the successful mission. The Rosetta mission will end with the controlled decent of the spacecraft onto the surface of comet 67P/Churyumov-Gerasimenko at around 7:20 a.m.

Rosetta set for a grand finale by diving into cometary cave

Rosetta's final order is in: go caving. After two years orbiting 67P/Churyumov-Gerasimenko, the European Space Agency craft will crash into a cave on the comet's surface on 30 September.
Its target is a once-active pit nicknamed Deir el-Medina, after a village where pottery shards that provided detailed records of life in ancient Egypt were discovered in a similar-looking well. The cave sits in an area of deep pits, some of which occasionally erupt with spectacular dust jets.
