Approaching a comet in 3D
As Philae approached Comet 67P/Churyumov-Gerasimenko on 12 November 2014, the lander’s downward-looking camera ROLIS took images of the descent.
Now the ROLIS team from DLR has used two of them to produce a stereographic image. To appreciate the 3D effect, the image must be viewed with red-blue/green glasses.
This image combines two ROLIS images, acquired about an hour before the first touchdown at 15:34 GMT/16:34 CET (time onboard the spacecraft), which was confirmed on Earth at 16:03 GMT/17:03 CET. The images are separated by two minutes and the resolution is three metres per pixel.
The ROsetta Lander Imaging System (ROLIS) was developed by the DLR Institute of Planetary Research in Berlin, Germany, under the leadership of principal investigator Stefano Mottola.
