Rosetta captures steep one kilometre cliffs and boulder-strewn terrains


Low surface gravity of Comet CG means human would survive jump from cliff


The steep, ragged cliffs and boulder-strewn terrains on the surface of Comet Churyumov–Gerasimenko (Comet 67P) have been captured in images taken by the Rosetta spacecraft.

Rosetta, a space mission which has for the first time put a spacecraft in orbit around a comet and landed a robotic probe on its surface, is orbiting Comet 67P from a few miles away and sending data back to the European Space Agency mission control in Darmstadt, Germany.

The rugged cliffs and patches of smooth terrain were then identified by Stuart Atkinson, a British amateur astronomer, who zoomed in on views published by the ESA.

If so, some of the material that accretes into a comet is likely sourced from fairly large bodies.
