Fila found

“Fila found!” Under this title was published today a message in the official blog of the mission to comet 67P / Churyumov-Gerasimenko. Fila's photographs were received on September 2, one month before the end of the Rosetta mission, and show the position of the descent vehicle on the comet. Its position explains the great difficulties that arose with the establishment of communication with the device after landing.

The photo was taken by a narrow-angle camera of Rosetta from a distance of 2.7 km. Up to this point, the device was last seen on November 12, 2014, when it touched a comet in the region of Agilkia, named after the island on the Nile, adjacent to the island of Fila. Then the device rebounded and flew for two hours, until it was in the place where it was found on September 2. The exact position was unknown. Thanks to measurements obtained by radio methods, the location of the device was determined in an area of ​​tens of meters. Until recently, a number of potential objects in photographs of this region could not be identified due to the low resolution. There were pictures taken by Fila after landing. The photos showed a rock called “Perihelion Cliff”, under which it appeared.

The history of the mission is described in detail in the work of the GAISh “Rosetta and Fila at the goal: the mission to the comet Churyumov-Gerasimenko”

While Phily took off and fell, the comet continued to rotate, and quite quickly. Instead of a flat, open area, freely illuminated by the sun, there were rough stone slopes and gaps beneath the Philami. The descent vehicle finally stopped, but stopped in extremely difficult conditions. The probe is in the recess, among the high jagged boulders, near the blank wall, with one of its supports raised up, and the apparatus itself, almost all, is in deep shadow and is not visible in the photograph.


Only now, when the “Rosetta” was very close to the comet, was it possible to detect Fila. One pixel of this photo in the original resolution corresponds to 5 centimeters on the surface of the comet. Fila's case has a size of about 1 meter.

On September 3, the Rosetta mission will enter its final stage - the device will be sent to collide with a comet, during which scientists hope to get very detailed photos of the structure of the Maat region.
