Skyhook Balloon
Skyhook balloons were high-altitude balloons developed by Otto C. Winzen and General Mills, Inc. They were used by the United States Navy Office of Naval Research (ONR) in the late 1940s and 1950s for atmospheric research, especially for constant-level meteorological observations at very high altitudes. Instruments like the Cherenkov detector were first used on Skyhook balloons. Project Skyhook In the late 1940s, Project Skyhook was conceived of as a means by which plastic balloons could be used to transmit or send instruments into the stratosphere to conduct research. This project carried forward work from an earlier project, Helios, that General Mills and Jean Piccard initiated to use arrays of giant plastic balloons to carry humans aloft. Balloons, long used for collecting meteorological data, now offered the opportunity of collecting highly specialized information and photographs. The first Skyhook balloon was launched on September 25, 1947. The balloon was developed by ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Scientific explorations of the A ...

Deacon (rocket)
Deacon is the designation of an American sounding rocket. The Deacon was launched 90 times from 1947 to 1957 from Wallops Island, and it also was the rocket portion of the first rockoons, launched 1952 to 1956. The Deacon has a maximum flight height of 20 kilometers and a pay load ability of 17 kilograms. The takeoff thrust of the Deacon amounts to 27 kN, the takeoff weight In science and engineering, the weight of an object is the force acting on the object due to gravity. Some standard textbooks define weight as a vector quantity, the gravitational force acting on the object. Others define weight as a scalar qua ... 93 kg, the diameter 0.16 m and the length 3.28 m.

Rockoon
A rockoon (from ''rocket'' and ''balloon'') is a solid fuel sounding rocket that, rather than being immediately lit while on the ground, is first carried into the upper atmosphere by a gas-filled balloon, then separated from the balloon and ignited. This allows the rocket to achieve a higher altitude, as the rocket does not have to move under power through the lower and thicker layers of the atmosphere. The original concept was developed by Cmdr. Lee Lewis, Cmdr. G. Halvorson, S. F. Singer, and James A. Van Allen during the Aerobee rocket firing cruise of the U.S.S. ''Norton Sound'' on March 1, 1949. A serious disadvantage is that unpiloted balloons cannot be steered, and consequently the location from which the rocket is launched can be uncertain. Therefore, a large area for the fall of the rocket is required for safety reasons. Early atmospheric research ''Time'' magazine reported in 1959: "Van Allen's 'Rockoons' could not be fired in Iowa for fear that the spent rockets ...

United States Atomic Energy Commission
The United States Atomic Energy Commission (AEC) was an agency of the United States government established after World War II by U.S. Congress to foster and control the peacetime development of atomic science and technology. President Harry S. Truman signed the McMahon/Atomic Energy Act on August 1, 1946, transferring the control of atomic energy from military to civilian hands, effective on January 1, 1947. This shift gave the members of the AEC complete control of the plants, laboratories, equipment, and personnel assembled during the war to produce the atomic bomb. An increasing number of critics during the 1960s charged that the AEC's regulations were insufficiently rigorous in several important areas, including radiation protection standards, nuclear reactor safety, plant siting, and environmental protection. By 1974, the AEC's regulatory programs had come under such strong attack that the U.S. Congress decided to abolish the AEC. The AEC was abolished by the Ener ...

Winzen Research
Winzen Research Inc, Minneapolis, Minnesota, created balloons in the 1950s and 1960s that were used by the United States Navy in its Projects Helios, Skyhook, and Strato-Lab. Balloons were also sold to the United States Air Force for use in Project Manhigh and for a secret reconnaissance mission, called Moby Dick, to overfly the Soviet Union. Otto C. Winzen developed the use of polyethylene resin for plastic balloons. Polyethylene balloons vastly reduced the weight in comparison with previously used rubber materials. Polyethylene was light, relatively cheap, and unaffected by ultraviolet radiation. Winzen refined the manufacturing techniques to reduce the plastics used in the balloons to less than the thickness of a human hair The company was created by Otto Winzen and his wife Vera Simons. Vera, eventually an accomplished balloonist herself, borrowed money from her parents to help start Winzen Research. She held over two-thirds ownership of the company and became its vice pres ...
