The defeated Titans were then cast into a shadowy underworld region known as Tartarus. Atlas, one of the titans who fought against Zeus, was punished by having to hold up the sky. After the battle with the Titans, Zeus shared the world with his elder brothers, Poseidon and Hades, by drawing lots: Zeus got the sky and air, Poseidon the waters, and Hades the world of the dead (the underworld). The ancient Earth, Gaia, could
Nike Zeus warhead. There were concerns that if the Zeus' own radars were used for this ranging measure, any systematic error in ranging would also be present in the test data, and thus would be hidden. The solution was the use of a separate UHF-frequency transmitter in the warhead reentry vehicle, and a receiver in the Zeus. The received signal was retransmitted to the ground, where its Doppler shift was examined to extract the range information. These instruments eventually demonstrated that the Zeus' own tracking information was accurate. For visual tracking, a small conventional warhead was used, which provided a flash that
