Space exploration related samples

1.Although studies from earth using optical and radio telescopes had accumulated much data on the nature of celestial bodies, it was not until after World War II that the development of powerful rockets made direct space exploration a technological possibility. The first artificial satellite, Sputnik I, was launched by the USSR on Oct. 4, 1957, and spurred the dormant U.S. program into action, leading to an international competition popularly known as the “space race.” Explorer I, the first American satellite, was launched on Jan. 31, 1958.

2.In the decade following Sputnik I, the United States and the USSR between them launched about 50 space probes to explore the moon. The first probes were intended either to pass very close to the moon or to crash into it hard landing. Later probes made soft landings with instruments intact and achieved stable orbits around the moon.

3.Human spaceflight has progressed from the simple to the complex, starting with suborbital flights; subsequent highlights included the launching of a single astronaut in orbit, the launching of several astronauts in a single capsule, the rendezvous and docking of two spacecraft, the attainment of lunar orbit, and the televised landing of an astronaut on the moon. The first person in earth orbit was a Soviet cosmonaut, Yuri Gagarin, in Vostok 1 on Apr. 12, 1961.

4.space shuttle, reusable U.S. space vehicle . Developed by the National Aeronautics and Space Administration and officially known as the Space Transportation System, it was the world’s first reusable spacecraft that carried human beings into earth orbit. It consisted of a winged orbiter, two solid-rocket boosters, and a large external fuel tank. As with previous spacecraft, the shuttle was launched from a vertical position.

5.There are six basic parameters that determine whether an environment is suitable for life as we know it: temperature, pressure, salinity, acidity, water availability, and oxygen content. Advanced life is restricted to a narrow range of these parameters, but primitive microorganisms exist over a much wider range. Data already collected by space probes essentially rule out advanced life on other planets of our solar system.

6.Artificial satellite that functions as part of a global radio-communications network. Echo 1, the first communications satellite, launched in 1960, was an instrumented inflatable sphere that passively reflected radio signals back to earth. Later satellites carried with them electronic devices for receiving, amplifying, and rebroadcasting signals to earth. Relay 1, launched in 1962 by the National Aeronautics and Space Administration (NASA), was the basis for Telstar 1, a commercially sponsored experimental satellite.

7.The Soviet Union launched the core module of the Mir space station in Feb., 1986. It was enlarged several times so that it could accommodate a crew of up to six cosmonauts. The Mir program was enhanced by having international teams conduct experiments at the station; Afghanistan, Bulgaria, France, Germany, Great Britain, India, Japan, Syria and the United States, in addition to Russia and other nations that were formerly part of the Soviet Union, participated.

8.The Global Positioning System (GPS), whose satellites replaced the Transit series, uses a web of 24 Navstar satellites in 12-hour orbits. The first Navstar satellite was launched in 1989, and the system began full operation in the 1990s. The satellites broadcast time and position messages continuously, and GPS receivers employ the more accurate triangulation method to determine position; the signals picked up by a GPS receiver can calculate position to within a few yards.
