End of Life
When satellites reach the end of their mission, satellite operators have the option of de-orbiting the satellite, leaving the satellite in its current orbit or moving the satellite to a graveyard orbit. Historically, due to budgetary constraints at the beginning of satellite missions, satellites were rarely designed to be de-orbited. One example of this practice is the satellite Vanguard 1. Launched in 1958, Vanguard 1, the 4th manmade satellite put in Geocentric orbit, was still in orbit as of August 2009.
Instead of being de-orbited, most satellites are either left in their current orbit or moved to a graveyard orbit. As of 2002, the FCC now requires all geostationary satellites to commit to moving to a graveyard orbit at the end of their operational life prior to launch.

Famous quotes containing the word life:
“O, reason not the need! Our basest beggars
Are in the poorest thing superfluous.
Allow not nature more than nature needs,
Man’s life is cheap as beast’s. Thou art a lady;
If only to go warm were gorgeous,
Why, nature needs not what thou gorgeous wear’st,
Which scarcely keeps thee warm. But, for true need—
You heavens, give me that patience, patience I need!”
—William Shakespeare (1564–1616)
