	Centaur
		Dwelling in the mountains of Thessaly and Arcadia, in the north of Greece, the centaurs were the offspring of Ixion and Nephele, the rain-cloud.
		Alternatively, the centaurs were the offspring of Kentauros (the son of Ixion and Nephele) and some Magnesian mares or of Apollo and Hebe.
		Centaurs are best known for their fight with the Lapithae, caused by their attempt to carry off Hippodamia (a "horse"woman herself) on the day of her marriage to Peirithous, king of the Lapithae, himself the son of Ixion (illustration, left).

		The Centaur rocket is a high-energy upper stage designed for use on satellite launch vehicles, boosting the satellite into its final orbit or, in the case of interplanetary probes, to escape velocity.
		Centaur was the brain child of Karel J. "Charlie" Bossart (the man behind the Atlas booster) and Dr. Krafft A. Ehriche, both Convair employees.
		Centaur was named after the Greek mythological race of centaurs.

		The rocket is 105 miles in altitude, 805 miles downrange from the launch pad, traveling at 11,800 miles per hour.
		Centaur upper stage liquid hydrogen and oxygen tanking reached flight level earlier, meaning the rocket is now fully fueled for launch.

	Protecting Space Systems from Lightning
		After launch, a rocket is exposed to the threat of lightning triggered by the presence of the launch vehicle itself and its long, conducting plume, which together can locally enhance the atmospheric electric field to its breakdown value.
		The high conductivity of the rocket and its plume causes the fields at the leading end of the rocket and the trailing end of the plume to have similar electric potentials; the voltage difference between these points is essentially zero.
		This means that the potential at the upper end of the rocket is approximately the same as the potential of the undisturbed ambient field at the lower end of the rocket's conducting plume.

	Centaur (rocket)
		A powerful upper-stage rocket that can be mated to an Atlas or Titan launch vehicle.
		The Centaur was America’s first cryogenic rocket, running on a combination of liquid hydrogen and liquid oxygen, and was developed under the direction of Lewis Research Center.
		Until early 1974, Centaur was used exclusively in tandem with Atlas but was then adapted for mating to the Titan III to boost heavier payloads into Earth orbit and interplanetary trajectories.

		The hot gases, emerging from the rocket nozzle at velocities of 9000 to 12,000 feet per second and temperatures of about 6000°F, are met with a drenching spray of water and quickly cooled to steam temperature and slowed to a velocity of about 25 feet per second.
		The modifications include a large vacuum tank which houses the rocket engine, a long, water cooled diffuser section into which the hot engine exhaust is funneled, an inter-cooler for cooling the exhaust gases, and two gas ejectors to provide the pumping necessary to maintain the low vacuum environment during testing.
		The technology used to build the Centaur, Saturn, and current Space Shuttle rockets can be directly attributed to the work of the Lewis Research Center in the RETF in its effort to support the continuing propulsion needs of NASA for its many space programs and missions.
