The chameleon comet’s nucleus became progressively less red as it made its close pass around the Sun, and then red again as it returned to deep space.

Before Churyumov—Gerasimenko's perihelion passage in , its rotational period was During this perihelion passage, it decreased to The Rosetta mission was the first mission to include an orbiter that accompanied a comet for several years, as well as a lander that collected close-up data from the comet's surface.
The mission launched in , arrived at comet 67P in , and concluded with a touchdown on the comet's surface in As preparation for the Rosetta mission, Hubble Space Telescope pictures taken on 12 March were closely analysed.
An overall 3D model was constructed and computer-generated images were created. On 25 April , the most detailed observations until that time were taken with the 2-metre Faulkes Telescope by N.
Howes, G. Sostero and E. Guido while it was at its aphelion. On 6 June , water vapor was detected being released at a rate of roughly 1 litre per second 0.
Descent of a small lander occurred on 12 November Because of its low relative mass, landing on the comet involved certain technical considerations to keep Philae anchored.
The probe contains an array of mechanisms designed to manage Churyumov—Gerasimenko's low gravity, including a cold gas thruster , harpoons, landing-leg-mounted ice screws, and a flywheel to keep it oriented during its descent.
The lander bounced twice and only came to rest when it made contact with the surface for the third time,  two hours after first contact.
Contact with Philae was lost on 15 November because of dropping battery power. The European Space Operations Centre briefly reestablished communications on 14 June and reported a healthy spacecraft but communications were lost again soon after.
It had come to rest in a crack with only its body and two legs visible. While the discovery solves the question of the lander's disposition, it also allows project scientists to properly contextualise the data it returned from the comet's surface.
The composition of water vapor from Churyumov—Gerasimenko, as determined by the Rosetta spacecraft, is substantially different from that found on Earth.
The ratio of deuterium to hydrogen in the water from the comet was determined to be three times that found for terrestrial water.
This makes it unlikely that water found on Earth came from comets such as Churyumov—Gerasimenko. Beneath that is hard ice, or a mixture of ice and dust.
Porosity appears to increase toward the center of the comet. The nucleus of Churyumov—Gerasimenko was found to have no magnetic field of its own after measurements were taken during Philae 's descent and landing by its ROMAP instrument and Rosetta 's RPC-MAG instrument.
This suggests that magnetism may not have played a role in the early formation of the Solar System, as had previously been hypothesized.
Measurements by the COSAC and Ptolemy instruments on the Philae 's lander revealed sixteen organic compounds , four of which were seen for the first time on a comet, including acetamide , acetone , methyl isocyanate and propionaldehyde.
Neither Rosetta nor Philae is equipped to search for direct evidence of organisms. Solid organic compounds were also found in the dust particles emitted by the comet; the carbon in this organic material is bound in "very large macromolecular compounds", analogous to the insoluble organic matter in carbonaceous chondrite meteorites.
Scientists think that the observed cometary carbonaceous solid matter could have the same origin as the meteoritic insoluble organic matter, but suffered less modification before or after being incorporated into the comet.
One of the most outstanding discoveries of the mission so far is the detection of large amounts of free molecular oxygen O 2 gas surrounding the comet.
Current solar system models suggest the molecular oxygen should have disappeared by the time 67P was created, about 4. On 3 July , researchers reported that molecular oxygen is not made on the surface of comet 67P, a finding that supports the notion that the oxygen comes from the body of the comet, and may be primordial.
As seen by the Very Large Telescope on 11 August . Phosphorus-bearing molecules found in a star-forming region and comet 67P.

Greyscale photograph of Comet Churyumov—Gerasimenko taken by the Rosetta spacecraft. From earlier Hubble Space Telescope observations, we expected 67P to be more of a diamondshaped object.
The peculiar bilobate shape of the comet was a big surprise. The resemblance to a rubber ducky was striking. The team quickly adopted the duck nomenclature not just for the humor of it but as a useful orientation: when somebody talked about the neck, everybody knew where to look.
The layers do not match across the two lobes, suggesting that the nucleus began as two independent objects that merged in a gentle collision.
We also saw a contrast between smooth, dust-covered areas and rugged terrains. Rosetta inspected the comet very closely, selecting a landing site and then deploying Philae late in while the low activity provided a safer environment for close approaches.
Over the course of the mission, the outgassing gradually increased to several hundred kilograms per second during its peak activity some weeks after perihelion.
The CONSERT experiment passed radio waves through the nucleus between the orbiter and the lander. The waves did not bounce off many internal boundaries, so the interior is probably mostly homogeneous.
The surface itself is very dark, very hard, very dry lacking much water ice , and rich in organic compounds. The southern hemisphere appeared rugged and more consolidated, with little dust and a flatter terrain fewer cliffs and pits than the northern hemisphere.
