Moon/Saturn

Saturn is the second-largest planet in the solar system, after Jupiter. Its equatorial radius is 37,448 miles (60,268 km), about nine times that of Earth, and its mass is 568.46 x 1024 kg, about 95 times that of Earth. As of early 2007, scientists had found 56 satellites of Saturn, the largest of which is Titan, with a radius of 8,448 feet (2,575 km, about 50 percent larger than that of Earth s Moon), and a mass of 1,345.5 x IO20 kg (about twice that of the Moon). Saturn s density is 0.687 g/cm3, less than that of water. This fact means that (if one could find a body of water large enough) Saturn would float on water. It is the only planet with a density less than that of water. 

In some alchemical works of that time, the planets were associated with colors as well as metals. Gold and silver were of course associated with the sun and moon. Saturn was represented by brown, Venus by green, Jupiter by blue, and Mars by red.70... 

A final, somewhat variable outlet for large-scale liquid oxygen is as oxidant in rocket fuels for space exploration, satellite launching and space shuttles. For example, in the Apollo mission to the moon (1979), each Saturn 5 launch rocket used 1270 m (i.e. 1.25 million litres or 1450 tonnes) of liquid oxygen in Stage 1, where it oxidized the kerosene fuel (195 000 1, or about 550 tonnes) in the almost unbelievably short time of 2.5 min. Stages 2 and 3 had 315 and 76.3 m of liquid O2 respectively, and the fuel was liquid FI2. 

Our solar system consists of the Sun, the planets and their moon satellites, asteroids (small planets), comets, and meteorites. The planets are generally divided into two categories Earth-like (terrestrial) planets—Mercury, Venus, Earth, and Mars and Giant planets—Jupiter, Saturn, Uranus, and Neptune. Little is known about Pluto, the most remote planet from Earth.

The next most likely possibility is cometary delivery of the atmosphere but again there are some problems with the isotope ratios, this time with D/H. The cometary D/H ratios measured in methane from Halley are 31 3 x 10-5 and 29 10 x 10-5 in Hayuatake and 33 8 x 10-5 in Hale-Bopp, whereas methane measurements from Earth of the Titan atmosphere suggest a methane D/H ratio of 10 5 x 10-5, which is considerably smaller than the ratio in the comets. The methane at least in Titan s atmosphere is not exclusively from cometary sources. Degassing of the rocks from which Titan was formed could be a useful source of methane, especially as the subnebula temperature around Saturn (100 K) is somewhat cooler than that around Jupiter. This would allow volatiles to be more easily trapped on Titan and contribute to the formation of a denser atmosphere. This mechanism would, however, apply to all of Saturn s moons equally and this is not the case. 

Since liquid hydrogen has the greatest energy content per unit weight of any fuel, NASA used liquid hydrogen as the primary fuel for the Saturn 5 moon rockets and the Space Shuttle. 

In one sense, the creation of alchemy represented a step backward. The Egyptians had known seven metallic elements gold, silver, copper, tin, iron, lead, and mercury, which they associated with the seven planets (Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn, respectively). The Greeks, however, failed to recognize them as distinct elements. According to the Aristotelian theory, the metals were mixtures of the traditional four elements. This idea seemed to... 

Post-WWII. After WWII most LP R D shifted from Germany to the USA and the USSR. Technical progress since 1945 in LP for rockets can be characterized by a host of minor improvements rather than major advances, and some spectacular applications of LP in rockets for military use and for space exploration, eg, in ICBM s (Intercontinental Ballistic Missiles) and in USA USSR Moon, Mars Venus shots . Thus the major developments since WWII have been primarily in the application of existing, though improved, propulsion systems to such highly publicized rockets as Sputnik, Vanguard, Soyuz, Saturn, Vostok, Apollo, Explorer, etc...
