Rosetta’s deployment of Philae to land on Comet 67P/Churyumov–Gerasimenko.
The animation begins with Philae still on Rosetta, which will come to within about 22.5 km of the centre of the nucleus to release the lander on 12 November 2014.
The animation then shows Philae being ejected by Rosetta and deploying its own three legs, and follows the lander’s descent until it reaches the target site on the comet about seven hours later. The animation is speeded up, but the comet rotation is true: in the time it takes for Philae to descend, the nucleus has rotated by more than 180º (the comet’s rotation period is 12.4 hours).
The final steps of Philae’s descent towards the comet are shown as seen by a hypothetical observer close to the landing site on the comet.
Acknowledgement: The background image of the sequence showing Philae closing in on the landing site was taken by Rosetta’s OSIRIS narrow-angle camera (ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA) on 14 September 2014 from a distance of about 30 km.
Philae was provided by a consortium led by DLR, MPS, CNES and ASI.
