“Etna is like the Moon”. Space robots walking on the sand of the volcano

PIAN DEL LAGO – From the spaceship he takes his first steps on the dark dust, slipping a little. He turns his head left and right, sees an obstacle and turns around it. That stone looks beautiful. He picks it up to take it home, like a child with a colored stone. His companion, a few meters ahead, is already placing the antennas that will allow communication even on the hidden side of the Moon, where the Earth cannot send or receive signals and where you are completely alone in space.
