This image was taken yesterday, January 14 by the European Space Agency's Huygens spacecraft during the successful landing on Titan.
This is an image that has been processed and added colors that reflect the colors measured by the spacecraft's instruments and give a better picture of the true color of the surface.
The scientists thought that the surface was mostly filled with ice blocks, but it seems to be more pebbles. The two rock-like objects located slightly below the center of the image are 15 centimeters in diameter (the left one) and 4 centimeters on the right, about 85 centimeters away from Huygens.
The surface is darker than previously expected, and consists of a mixture of water and hydrocarbon ice. There is also evidence of erosion at the base of these features, indicating possible river flow activity.
The image was taken by the Descent Camera/Spectral Radiometer - one of NASA's two instruments on the spacecraft.
Left: A composite image created from photographs taken during the landfall on the moon Titan and it shows the boundaries between the bright raised plains, filled with what appear to be drainage channels, and the darker lower areas. The image was taken from a height of 8 kilometers with a resolution of 20 meters per pixel.
In the right picture - the same picture as the color picture above - a photo from the ground level after landing, plus the measurements of the different rocks.
