STS-55
STS-55, or Deutschland 2 (D-2), was the 55th overall flight of the NASA Space Shuttle and the 14th flight of Shuttle ''Columbia''. This flight was a multinational Spacelab flight involving 88 experiments from eleven different nations. The experiments ranged from biology sciences to simple Earth observations. Crew Backup crew Mission highlights ''Columbia'' carried to orbit the second reusable German Spacelab D-2 and demonstrated the shuttle's ability for international cooperation, exploration, and scientific research in space. The Spacelab module and an exterior experiment support structure contained in ''Columbia''s payload bay comprised the Spacelab D-2 payload. The first German Spacelab flight, D-1, flew Shuttle mission STS-61-A in October 1985. The United States and Germany gained valuable experience for future space station operations. The D-2 mission, as it was commonly called, augmented the German microgravity research program started by the D-1 mission. The ...

Spacelab
Spacelab was a reusable laboratory developed by European Space Agency (ESA) and used on certain spaceflights flown by the Space Shuttle. The laboratory comprised multiple components, including a pressurized module, an unpressurized carrier, and other related hardware housed in the Shuttle's cargo bay. The components were arranged in various configurations to meet the needs of each spaceflight. Spacelab components flew on a total of about 32 Shuttle missions, depending on how such hardware and missions are tabulated. Spacelab allowed scientists to perform experiments in microgravity in geocentric orbit. There was a variety of Spacelab-associated hardware, so a distinction can be made between the major Spacelab program missions with European scientists running missions in the Spacelab habitable module, missions running other Spacelab hardware experiments, and other Space Transportation System (STS) missions that used some component of Spacelab hardware. There is some variation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Space Shuttle Columbia
Space Shuttle ''Columbia'' (OV-102) was a Space Shuttle orbiter manufactured by Rockwell International and operated by NASA. Named after the first American ship to circumnavigate the upper North American Pacific coast and the female personification of the United States, ''Columbia'' was the first of five Space Shuttle orbiters to fly in space, debuting the Space Shuttle launch vehicle on its maiden flight in April 1981. As only the second full-scale orbiter to be manufactured after the Approach and Landing Test vehicle ''Enterprise'', ''Columbia'' retained unique features indicative of its experimental design compared to later orbiters, such as test instrumentation and distinctive black chines. In addition to a heavier fuselage and the retention of an internal airlock throughout its lifetime, these made ''Columbia'' the heaviest of the five spacefaring orbiters; around heavier than ''Challenger'' and heavier than '' Endeavour''. ''Columbia'' also carried ejection seats ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Multilateralism
In international relations, multilateralism refers to an alliance of multiple countries pursuing a common goal. Definitions Multilateralism, in the form of membership in international institutions, serves to bind powerful nations, discourage unilateralism, and gives small powers a voice and influence that they could not otherwise exercise. For a small power to influence a great power, the Lilliputian strategy of small countries banding together to collectively bind a larger one can be effective. Similarly, multilateralism may allow one great power to influence another great power. For a great power to seek control through bilateral ties could be costly; it may require bargaining and compromise with the other great power. Miles Kahler defines multilateralism as "international governance" or global governance of the "many," and its central principle was "opposition o bilateral discriminatory arrangements that were believed to enhance the leverage of the powerful over the weak ...

Space Exploration
Space exploration is the use of astronomy and space technology to explore outer space. While the exploration of space is carried out mainly by astronomers with telescopes, its physical exploration though is conducted both by uncrewed robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one of the main sources for space science. While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to become a reality. The world's first large-scale experimental rocket program was Opel-RAK under the leadership of Fritz von Opel and Max Valier during the late 1920s leading to the first crewed rocket cars and rocket planes, which paved the way for the Nazi era V2 program and US and Soviet activities from 1950 onwards. The Opel-RAK program and the spectacular p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Method
The scientific method is an Empirical evidence, empirical method for acquiring knowledge that has characterized the development of science since at least the 17th century (with notable practitioners in previous centuries; see the article history of scientific method for additional detail.) It involves careful observation, applying rigorous skepticism about what is observed, given that Philosophy of science#Observation inseparable from theory, cognitive assumptions can distort how one interprets the Perception#Process and terminology, observation. It involves formulating Hypothesis, hypotheses, via Inductive reasoning, induction, based on such observations; the testability of hypotheses, experimental and the measurement-based statistical testing of Deductive reasoning, deductions drawn from the hypotheses; and refinement (or elimination) of the hypotheses based on the experimental findings. These are ''principles'' of the scientific method, as distinguished from a definitive ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
