DBCC CHECKDB是什么意思

Outer space

"Deep space" redirects here. For the NASA space probes, see Deep Space 1 and Deep Space 2. 。

Layers of Atmosphere - not to scale (NOAA)Outer space, also simply called space, refers to the relatively empty regions of the universe outside the atmospheres of celestial bodies. Outer space is used to distinguish it from airspace (and terrestrial locations). Contrary to popular understanding, outer space is not completely empty but contains a low density of particles, predominantly hydrogen gas as well as electromagnetic radiation.。

Earth's boundary。

There is no discrete boundary between the Earth's atmosphere and space as the atmosphere gradually attenuates with increasing altitude. If the atmosphere had a constant temperature, its pressure would decrease exponentially from a sea-level value of 100 kPa (1 bar) toward its final value of zero. The Federation Aeronautique Internationale has established the Kármán line at an altitude of 100 km (62 miles) as a working definition for the boundary between atmosphere and space. The United States designates people who travel above an altitude of 50 miles (80 km) as astronauts. During re-entry, 400,000 feet (75 miles or 120 km) marks the boundary where atmospheric drag becomes noticeable.。

Solar System

Outer space within the solar system is called interplanetary space, which passes over into interstellar space at the heliopause. The vacuum of outer space is not really empty; it is sparsely filled with several dozen organic molecules discovered to date by microwave spectroscopy. According to the Big bang theory,2.7 K blackbody radiation was left over from the 'big bang' and the origin of the universe, and cosmic rays, which include ionized atomic nuclei and various subatomic particles. There is also gas, plasma and dust, and small meteors and material left over from previous manned and unmanned launches that are a potential hazard to spacecraft. Some of this debris re-enters the atmosphere periodically.。

The absence of air makes outer space (and the surface of the Moon) ideal locations for astronomy at all wavelengths of the electromagnetic spectrum, as evidenced by the spectacular pictures sent back by the Hubble Space Telescope, allowing light from about 14 billion years ago, back almost to the time of the Big Bang to be observed. Pictures and other data from unmanned space vehicles have provided invaluable information about the planets, asteroids and comets in our solar system.。

Pressure variance。

Going from sea level to outer space produces a pressure difference of only about 15 lbf/sq in, equal to surfacing from an underwater depth of about 34 ft (10 m).。

[edit]

Vacuum

Contrary to popular belief a person suddenly exposed to the vacuum would not explode, but it would take a matter of milliseconds for a person to freeze to death. Water vapor would start to boil off from exposed areas such as the cornea of the eye, and along with oxygen, from membranes inside the lungs. Here is NASA's explanation.。

[edit]

Satellites

There are many artificial satellites orbiting the Earth, including geosynchronous communication satellites 35,786 km (22,241 miles) above mean sea level at the Equator. Their orbits never "decay" because there is almost no matter there to exert frictional drag. There is also increasing reliance, for both military and civilian uses, of satellites which enable the Global Positioning System (GPS). A common misconception is that people in orbit are outside Earth's gravity because they are obviously "floating". They are floating because they are in "free fall": the force of gravity and their linear velocity is creating an inward centripetal force which is stopping them from flying out into space. Earth's gravity reaches out far past the Van Allen belt and keeps the Moon in orbit at an average distance of 384,403 km (238,857 miles). The gravity of all celestial bodies drops off toward zero with the inverse square of the distance.。

Space does not equal orbit。

To perform an orbital space flight, a spacecraft must go higher and faster than for a sub-orbital space flight. A spacecraft has not made orbit until it is circling the Earth at a sufficiently great speed such that the weight of the spacecraft is exactly equal to the centripetal acceleration required to keep it in a circular orbit (see circular motion). It must not only rise above the atmosphere, but must also achieve a sufficient orbital speed (angular velocity). For a low Earth orbit, this is about 7.9 km/s (18,000 mph). Konstantin Tsiolkovsky was the first to realize that, given the energy available from any available chemical fuel, a several-stage rocket would be required. The escape velocity to pull free of Earth’s gravitational field altogether and move into interplanetary space is about 40,000 km/h (25,000 mph or 11,000 m/s). The energy required to reach velocity for low Earth orbit (32 MJ/kg) is about twenty times the energy required simply to climb to the corresponding altitude (10 kJ/(km·kg)).。

There is a major difference between sub-orbital and orbital space flights. Minimal altitude for a stable orbit around the Earth, without excessive atmospheric drag, begins at around 350 km (220 miles) above mean sea level. A common misunderstanding about the boundary to space is that orbit occurs simply by reaching this altitude. Achieving orbital speed can theoretically occur at any altitude, although atmospheric drag precludes an orbit that is too low. At sufficient speed, an airplane would need a way to keep it from flying off into space, but at present, this speed is several times greater than anything within reasonable technology.。
