* boost phase: 3 to 5 minutes ( shorter for a solid rocket than for a liquid-propellant rocket ); altitude at the end of this phase is typically 150 to 400 km depending on the trajectory chosen, typical burnout speed is 7 km / s, up to the speed of Low Earth Orbit.

Modern communications satellites typically use geosynchronous orbits, Molniya orbits or Low Earth orbits.

Originally " drop-in " replacements were considered for higher performance, but a larger replacement for the S-IVB stage was later studied for missions to Mars and other high-load profiles, known as the S-N. Nuclear thermal space " tugs " were planned as part of the Space Transportation System to take payloads from a propellant depot in Low Earth Orbit to higher orbits, the Moon, and other planets.

The 40 megajoules per kilogram or less kinetic energy of projectiles launched at up to 9000 m / s velocity ( if including extra for drag losses ) towards Low Earth Orbit is a few kilowatt-hours per kilogram if efficiencies are relatively high, which accordingly has been hypothesized to be under $ 1 of electrical energy cost per kilogram shipped to LEO, though total costs would be far more than electricity alone.

To launch a space vehicle with humans on board, a mass driver's track would need to be several hundreds of kilometers long if providing almost all the velocity to Low Earth Orbit, though lesser length can provide major launch assist.

Batteries are typically connected to the bus via a battery charge regulator, and the batteries are used to provide electrical power during periods when primary power is not available, for example when a Low Earth Orbit ( LEO ) spacecraft is eclipsed by the Earth.

A Low Earth Orbit ( LEO ) typically is a circular orbit about above the earth ’ s surface and, correspondingly, a period ( time to revolve around the earth ) of about 90 minutes.

Changing geomagnetic conditions can induce changes in atmospheric density causing the rapid degradation of spacecraft altitude in Low Earth orbit.

Magnetometers used in the Earth sciences are called geophysical surveys, a term that also embraces a wide range of other geophysical techniques including gravity, seismic refraction, seismic reflection, electromagnetics ( EM ), induced polarisation ( IP ), magneto-tellurics ( MT ), controlled source magneto-tellurics ( CSAMT ), sub-audio magnetics ( SAM ), mise-a-la-masse, resistivity, self Potential ( SP ) and Very Low Frequency ( VLF ).

Low Earth orbit satellites take advantage of the fact that certain polar orbits set near the terminator do not suffer from eclipse, therefore their solar cells are continuously lit by sunlight.

Unless Low Earth Orbit satellites are routinely boosted to higher orbits, they slowly fall, and eventually burn up in Earth's atmosphere.

defense system, a satellite constellation of 4, 600 kinetic interceptors ( KE ASAT ), of 100 lb ( 45 kg ) each, in Low Earth orbit, and their associated tracking systems.

Computer controlled motorized parabolic dish antenna for tracking Low Earth orbit | LEO weather satellites. Polar orbiting weather satellites circle the Earth at a typical altitude of 850 km ( 530 miles ) in a north to south ( or vice versa ) path, passing over the poles in their continuous flight.

Low earth orbiting satellites are less expensive to launch into orbit than geostationary satellites and, due to proximity to the ground, do not require as high signal strength ( Recall that signal strength falls off as the square of the distance from the source, so the effect is dramatic ).

In Europe K < sub > u </ sub > band is used from 10. 7 to 12. 75 GHz ( LOF Low 9. 750 GHz, LOF High 10. 600 GHz ) for direct broadcast satellite services such as those carried by the Astra satellites.

The KH-8, codenamed Gambit 3 was a long-lived series of reconnaissance satellites of the " Key Hole " ( KH ) series used by the United States from July 1966 to April 1984, and also known as Low Altitude Surveillance Platform.

Most amateur satellites are Low Earth Orbit satellites, or LEO's as they are affectionately known, and generally are about 450 miles high.

A complement of satellites in low earth orbit was planned as part of the program ( SBIRS Low ), but this has been moved into the STSS program.

The SBIRS Low program was originally expected to consist of about 24 satellites in low earth orbit.

The MetOp program, a collaboration between NOAA and EUMETSAT, has switched to Low Rate Picture Transmission ( LRPT ) for its new polar-orbit satellites and NOAA has stated they will not fly APT transmitters on POES vehicles after NOAA-N '.

The Low Earth Orbit satellites complete one earth orbit every 90 minutes.

we are stronger and more self-confident -- and Low cannot so easily put us to rights.

Conversely the use of true brass seems to have declined in Western Europe during this period in favour of gunmetals and other mixed alloys but by the end of the first Millennium AD brass artefacts are found in Scandinavian graves in Scotland, brass was being used in the manufacture of coins in Northumbria and there is archaeological and historical evidence for the production of brass in Germany and The Low Countries areas rich in calamine ore which would remain important centres of brass making throughout the medieval period, especially Dinant – brass objects are still collectively known as dinanterie in French.

Low serves are also used frequently, either forehand or backhand.

Low concentrations are not a problem for bacteria because they simply ignore the waste that surrounds the metals, attaining extraction yields of over 90 % in some cases.

Low cost, availability, and portability are cited by practitioners as qualities which make this common writing tool a convenient, alternative art supply.

Low, broken-in, soft-soled, non-marking shoes, such as dance shoes, sneakers, or sandals, are recommended and, in some places, required.

The term " Low Fantasy " is used to represent other types of fantasy, however, so while comic fantasies may also correctly be classified as low fantasy, many examples of low fantasy are not comic in nature.

Low carbohydrate diets such as Atkins and Protein Power are relatively high in protein and fats.

Low surface brightness dwarf galaxies are important sources of information for studying dark matter, as they have an uncommonly low ratio of visible matter to dark matter, and have few bright stars at the center which would otherwise impair observations of the rotation curve of outlying stars.

In English, the terms poniard and dirk are loaned during the late 16th to early 17th century, the latter in the spelling dork, durk ( presumably via Low German, Dutch or Scandinavian dolk, dolch, ultimately from a West Slavic tulich ), the modern spelling dirk dating to 18th-century Scots.

Low explosives are compounds where the rate of decomposition proceeds through the material at less than the speed of sound.

Low explosives are normally employed as propellants.

Low percentage gels are very weak and may break when you try to lift them.

Low numbers ( below 31 and especially below 12 ) are popular because people play birthdays as their so-called lucky numbers ; hence a win in which these numbers are over-represented is more likely to result in a shared payout.

Low frequency inductors are constructed like transformers, with cores of electrical steel laminated to prevent eddy currents.

While Dutch is classified as a Low Franconian language, the Dutch Low Saxon varieties, which are also defined as Dutch dialects, form a dialect continuum with the Westphalian language.

Low temperature, starvation of the cells and high multiplicity of infection ( MOI ) are known to favor lysogeny ( see later discussion ).
