Philae Lander Touches Down on a Comet | ESA Space Science HD Video
Показать описание
Coconut Science Lab:
When the Rosetta probe arrives at comet 67P/Churyumov-Gerasimenko in November 2014, it will come within 2.5 kilometers of the comet's surface to deploy Philae - which will then take around 2 hours to reach the surface.
Due to the comet's extremely low gravity, the probe's landing gear will absorb the small impact forces upon landing - while ice screws in Philae's feet and a harpoon system lock the probe to the surface.
Once anchored, the lander will begin its primary science mission, based on the 64-hour lifetime of its batteries. It will use solar cells to recharge the batteries, while attempting to operate for several further weeks or months - depending on the activity of the comet and how quickly the solar cells are covered in dust.
Please rate and comment, thanks!
