Space technology is technology Technology is a term referring to whatever can be said at any particular historical period, concerning the state of the art in the whole general field of practical know-how and tool use. It therefore encompasses all that can be said about arts, crafts, professions, applied sciences, and skills. By extension it can also refer to any systems or that is related to entering, and retrieving objects or life forms from space Outer space is the void that exists beyond any celestial body including the Earth. It is not completely empty (i.e. a perfect vacuum), but contains a low density of particles, predominantly hydrogen plasma, as well as electromagnetic radiation, magnetic fields, and neutrinos. Theoretically, it also contains dark matter and dark energy.

"Every day" technologies such as weather forecasting Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. Human beings have attempted to predict the weather informally for millennia, and formally since at least the nineteenth century. Weather forecasts are made by collecting quantitative data about the current, remote sensing Remote sensing is the small- or large-scale acquisition of information of an object or phenomenon, by the use of either recording or real-time sensing device that are wireless, or not in physical or intimate contact with the object (such as by way of aircraft, spacecraft, satellite, buoy, or ship). In practice, remote sensing is the stand-off, GPS The Global Positioning System is a space-based global navigation satellite system that provides reliable location and time information in all weather and at all times and anywhere on or near the Earth when and where there is an unobstructed line of sight to four or more GPS satellites. It is maintained by the United States government and is freely systems, satellite television Satellite television is television delivered by the means of communications satellite and received by a satellite dish and set-top box. In many areas of the world it provides a wide range of channels and services, often to areas that are not serviced by terrestrial or cable providers, and some long distance communications systems critically rely on space infrastructure. Of sciences astronomy Astronomy is a natural science that deals with the study of celestial objects and phenomena that originate outside the Earth's atmosphere (such as the cosmic background radiation). It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe and Earth sciences Earth science , is an all-embracing term for the sciences related to the planet Earth. It is arguably a special case in planetary science, the Earth being the only known life-bearing planet. There are both reductionist and holistic approaches to Earth sciences. The formal discipline of Earth sciences may include the study of the atmosphere, oceans (via remote sensing Remote sensing is the small- or large-scale acquisition of information of an object or phenomenon, by the use of either recording or real-time sensing device that are wireless, or not in physical or intimate contact with the object (such as by way of aircraft, spacecraft, satellite, buoy, or ship). In practice, remote sensing is the stand-off) most notably benefit from space technology.

Computers A computer is a programmable machine that receives input, stores and manipulates data//information, and provides output in a useful format and telemetry Telemetry is a technology that allows remote measurement and reporting of information. The word is derived from Greek roots tele = remote, and metron = measure. Systems that need external instructions and data to operate require the counterpart of telemetry, telecommand were once leading edge technologies that might have been considered "space technology" because of their criticality to boosters and spacecraft A spacecraft is a craft or machine designed for spaceflight. Spacecraft are used for a variety of purposes, including communications, earth observation, meteorology, navigation, planetary exploration and space tourism. Spacecraft and space travel are common themes in works of science fiction. They existed prior to the Space Race The Space Race was a technological and ideological competition between the Soviet Union and the United States (USA) for supremacy in outer-space exploration during the mid-to-late 20th century. The term refers to a specific period in human history, 1957-1975, and does not include subsequent efforts by these or other nations to explore space. The of the Cold War The Cold War was the continuing state of political conflict, military tension, proxy wars, and economic competition existing after World War II (1939–1945), primarily between the Soviet Union and its satellite states, and the powers of the Western world, particularly the United States. Although the primary participants' military forces never (between the USSR and the USA.) but their development was vastly accelerated to meet the needs of the two major superpowers' space programs. While still used today in spacecraft and missiles In common military parlance, the word missile describes a powered, guided munition that travels through the air or space, whilst the word rocket describes a powered, unguided munition. Unpowered, guided munitions are known as guided bombs. Powered munitions that travel through water are called torpedoes. A common further sub-division is to, the more prosaic applications such as remote monitoring (via telemetry) of patients, water plants, highway conditions, etc. and the widespread use of computers far surpasses their space applications in quantity and variety of application.

Space is such an alien environment that attempting to work in it requires new techniques and knowledge. New technologies originating with or accelerated by space-related endeavors are often subsequently exploited in other economic activities. This has been widely pointed to as beneficial by space advocates and enthusiasts favoring the investment of public funds in space activities and programs. Political opponents counter that it would be far cheaper to develop specific technologies directly if they are beneficial and scoff at this justification for public expenditures on space-related research.

What do you think of this new Space Technology?
Q. cool link i found on the new Chinese space craft engines and satellite. what do you think?
Asked by Michael F - Mon Sep 29 03:28:31 2008 - - 4 Answers - 0 Comments

A. Just because the Chinese say that it works, doesn't mean that it exists. But it would be good if it did., since it uses less energy than conventional engines. Time will tell whether it becomes commonplace. .
