The drawings the satellite made are replicas of the mysterious line carvings in Nazca, Peru.
Psychic Yauri Kellerman is a nod to "psychic" Uri Geller, famous for bending spoons on television. One way to note this, besides the name, is that the psychic is dressed in 1970s garb with a 1970s hairdo, circa the time Geller became a celebrity and bent spoons on television.
Besides the well known Nazca carvings, the two figures shown during the Yuri Gellermann interview are the Uffington White Horse and the Long Man of Wilmington.
