Spirits In The Sky

Written by Chris Meehan


From Elvis to Nick Drake,repparttar music lives on.

Elvis Presley securedrepparttar 109913 number one, last week, inrepparttar 109914 historic 1000th compilation ofrepparttar 109915 British charts, with A Fool Such As I ? 44 years since its original release. This is some achievement, but does his premature death have something to do with it? After all, a contemporary such as Jerry Lee Lewis, now well into pensionable age, doesn?t look likely to make a comeback atrepparttar 109916 top of present-day, mainstream play lists.

What?s at work here is that powerful emotion: nostalgia. Though Elvis was taken from us oncerepparttar 109917 ravages of middle age were pretty much advanced, our collective memory of him remains frozen at an earlier, more flattering time. We all like to recall him as that vital, charismatic, leathered-up, turbo-charged macho of Jail House Rock. His early death has ensured his musical immortality and that he remains forever young in our hearts.

From Glenn Miller to Buddy Holly, an untimely death has endowed a certain mystique torepparttar 109918 life and times ofrepparttar 109919 performer, not to mention: bankability, qualities that endure from beyondrepparttar 109920 grave. Just take a look atrepparttar 109921 number of Glenn Miller compilations that are periodically released andrepparttar 109922 success thatrepparttar 109923 musical ?Buddy? has had in recent times.

Jimi Hendrix and Jim Morrison left a vast, gaping void inrepparttar 109924 music landscape when they passed away, inrepparttar 109925 early 1970s. However, their musical legacy has taken on cult status. The posthumous marketing of Hendrix material (from huge quantities of available, unreleased studio sessions and recordings of live concerts) exceeds that which he released in his lifetime ? and though much of it falls well belowrepparttar 109926 sublime heights touched by: Are You Experienced, Axis: Bold As Love and Electric Leyland (recorded with his classic band,repparttar 109927 Jimi Hendrix experience), it hasn?t deterredrepparttar 109928 buying public from continuing to buy intorepparttar 109929 Hendrix legend.

Jim Morrison (wayward rock-child, touched byrepparttar 109930 spirit ofrepparttar 109931 Beat generation) with an exceptional talent for self-destruction, has been seen by many as a willing victim of rock and roll excess. His death in Paris in 1971, in his late 20s, and burial at Pere Lachaise cemetery (the resting place ofrepparttar 109932 great andrepparttar 109933 good: from Edith Piaf to Oscar Wilde) have all added torepparttar 109934 Morrison mythology, which has never lost its capacity to fascinate and sell records. Like Elvis,repparttar 109935 image that survives is that of an arresting and unblemished youth, before excess took its toll.

Any object that moves aroundrepparttar 109914 earth has an orbit. The orbit is defined by 3 factors. The first isrepparttar 109915 shape ofrepparttar 109916 orbit, which can be circular or elliptical. The second isrepparttar 109917 altitude ofrepparttar 109918 orbit. The altitude is constant for a circular orbit but changes constantly for an elliptical orbit. The third factor isrepparttar 109919 anglerepparttar 109920 orbit makes withrepparttar 109921 equator. An orbit that bringsrepparttar 109922 satellite overrepparttar 109923 poles or close to it has a large angle. An orbit that makesrepparttar 109924 satellite stay close torepparttar 109925 equator has a small angle.

Orbits depend onrepparttar 109926 missionrepparttar 109927 satellite was built for. The following orbits can be defined:

Low Earth Orbit

Satellites in low earth orbit (LEO) orbitrepparttar 109928 earth at altitudes of less than 2000 km (1242 miles). Satellites in LEO can get much clearer surveillance images and require much less power to transmit their data torepparttar 109929 earth.

Medium Earth Orbit

At an altitude of around 10.000 km (6.000 miles) a satellite is in medium earth orbit (MEO). This altitude balancesrepparttar 109930 advantages and disadvantages of LEO and GEO. MEO’s are used generally for navigational satellites and communications satellites.

Geostationary Orbit

A satellite in geostationary orbit orbitsrepparttar 109931 earth in exactly 1 day and is placed aboverepparttar 109932 equator. The angle withrepparttar 109933 equator is 0 degrees. As a resultrepparttar 109934 satellite seems to stand still as seen fromrepparttar 109935 earth. These satellites are used for communications and Satellite TV.

Polar Orbit

An orbit that goes over bothrepparttar 109936 North andrepparttar 109937 South Pole is called a Polar Orbit. The angle withrepparttar 109938 equator is 90 degrees. The advantage of these orbits is that they go overrepparttar 109939 poles. This may sound funny, but in reality most satellites never “see”repparttar 109940 poles. Most polar orbits are in LEO, but any altitude can be used for a polar orbit.

Polar orbits are used a lot by navigation satellites which have to provide navigational information all overrepparttar 109941 world, includingrepparttar 109942 poles.

Sun Synchronous Orbit

This is a very interesting type of orbit. Satellites in Sun Synchronous Orbit pass overrepparttar 109943 same locations on earth atrepparttar 109944 same time each day. Suppose a satellite in sun synchronous orbit passes over your house at 3 pm. The next timerepparttar 109945 satellite will pass over your house is 24 hours later atrepparttar 109946 same timerepparttar 109947 next day.
