According to someone at NASA: “Early this morning (October 6), we fired LADEE’s main engine in a braking maneuver known as the Lunar Orbit Insertion (LOI) burn. This slowed the spacecraft’s velocity enough for it to be captured by the Moon’s gravity. This critical burn went flawlessly and LADEE is now in lunar orbit! Two more main engine burns, on October 9 and 12 will adjust LADEE’s trajectory, settling it into its commissioning orbit.”
