... and they are Superconductivity and Superfluidity. Cryogenics first came about in 1877, when a Swiss Physicist named Rasul Pictet and a French Engineer named Louis P. Cailletet liquefied oxygen for the first time. Cailletet created liquid oxygen in his lab using a process known as adiabatic expansion, which is a "thermodynamic process in which the temperature of a gas is expanded without adding or extracting heat from the gas or the surrounding system"(Vance 26). At the same time Pictet used the "Joule-Thompson Effect," a thermodynamic process that states that the "temperature of a fluid is reduced in a process involving expansion below a certain temperatur ...

... and moisture into the atmosphere and this in turn alters wind and rainfall patterns around the world. The atmospheric cirulation also changes when the sea-surface temperatures in the eastern tropical Pacific rise above normal. In normal, non-El Nino conditions, the trade winds blow towards the west across the tropical Pacific. These winds pile up warm water in the west Pacific, so that the sea surface is about 1/2 meter higher at Indonesia than at Ecuador. The sea surface temperature is about 8 degrees C higher in the west, with cool termperatures off South America, dut to an upwelling of cold water from deeper levels. This cold water is nutrient-rich, supporti ...

... with in-flight accessibility, provided by investigators selected from the international science community. The Observatory objective is to have an operational lifetime in excess of 20 years. The SOFIA project is in the early full-scale stage. The start of detailed system design is anticipated in the Fall of 1996. The German Space Agency (DARA) is a partner with NASA in the SOFIA project. DARA will provide the telescope and NASA will provide the rest of the facility including the 747 aircraft, aircraft modifications, on-board mission control system, ground facilities and support equipment, overall management, system integration and operations. The SOFIA project ...
