The crater creation in single massive targets and in double ones was investigated.
The homogenous, flat outer crater zone differs from morphological features obtained by slumping or by downfaulting of a terraced zone.
Studies of the laser-created craters produced on solid surfaces at various experimental conditions.
At the positive focal point position, the craters have a semitoroidal shape, while at the negative position they resemble a hemisphere.
Our conclusions could be useful for future searching programs, which look for signs of ancient life forms in crater lakes.
To the lower right, stippled flecks form a panorama of hills and craters.
The amount of collapse is dependent on the size of the crater, the gravity constant and the target material.
An enlarged view of those spines (fig. 6 inset) show that they are located in crater-like holes in the tegument.
