The LADEE spacecraft made three "phasing orbits" of Earth before it accomplished a Lunar orbit insertion (LOI), which occurred at perigee of the third orbit using a three-minute engine burn [REF].
To handle potential off-nominal launch dispersions from the Minotaur V-which is a stack of five solid rocket stages, and is not considered to be a particularly precise rocket-in a propellant-efficient manner while leaving the orbit profile flexible to large dispersions in the initial injection orbit.
