The name of the spaceships - Icarus - is symbolic. Icarus is a character in Greek Mythology. His father, Daedalus, made a pair of wings for himself and his son so that they could escape from a prison. He made them from feathers and wax. Before they took off, Daedalus warned his son not to fly too close to the sun, as the wax will melt, nor too close to the sea, as the feathers will dampen. But overcome by the feeling that flying gave him, Icarus soared through the sky, too close to the sun. His wings melted and Icarus fell into the sea.
