The Earth Departure Stage (EDS) is the name given to the second stages of two Shuttle-Derived Launch Vehicles, the Ares V and the Block II Space Launch System. The EDS is used to boost the rocket's payload into a parking orbit around the Earth and from there send the payload out of low Earth orbit to its destination in a manner similar to that of the S-IVB rocket stage used on the Saturn V rockets that propelled the three-man Apollo missions to the Moon between 1968 and 1972.

Famous quotes containing the words earth, departure and/or stage:
“That air would disappear from the whole earth in time, perhaps; but long after his day. He did not know just when it had become so necessary to him, but he had come back to die in exile for the sake of it. Something soft and wild and free, something that whispered to the ear on the pillow, lightened the heart, softly, softly picked the lock, slid the bolts, and released the prisoned spirit of man into the wind, into the blue and gold, into the morning, into the morning!”
—Willa Cather (1873–1947)
“Nature seemed to have adorned herself for our departure with a profusion of fringes and curls, mingled with the bright tints of flowers, reflected in the water. But we missed the white water-lily, which is the queen of river flowers, its reign being over for this season.... Many of this species inhabit our Concord water.”
—Henry David Thoreau (1817–1862)
“The literary wiseacres prognosticate in many languages, as they have throughout so many centuries, setting the stage for new haut monde in letters and making up the public’s mind.”
—Fannie Hurst (1889–1968)
