   [1] [2] Boosters are traditionally necessary to launch spacecraft into low Earth orbit (absent a single-stage-to-orbit design), and are especially important for a space vehicle to go beyond Earth orbit. [citation needed] The booster is dropped to fall back to Earth once its fuel is expended, a point known as booster engine cut-off (BECO). [3]
