The reconnaissance of the comet’s surface included the search for a landing site for Rosetta’s companion probe, Philae. On September 15, ESA announced that scientists had chosen a spot on the comet’s “head” — the smaller of the two lobes that make up the bulk of the 2.5-mile-long (4km) comet. The site excites scientists because it shows hints of nearby cometary activity, and it thrills engineers because it appears to pose little risk to the lander making a successful touchdown. On September 26, ESA set November 12 as the target date for deploying Philae.
Here we present some of Rosetta’s best images of Comet 67P/Churyumov-Gerasimenko and the Philae landing site taken during September.
