On June 27 at 10:04 a.m. EDT, the spacecraft was about 2,400 miles from the moon. At that point, flight engineers at UC Berkeley issued the first commands to move it into orbit around the moon. Two more maneuvers helped fine-tune the position, and as of 12:30 p.m. EDT, ARTEMIS P1 is now in lunar orbit. ARTEMIS (“Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon’s Interaction with the Sun”) is the first mission ever to orbit the moon’s Lagrangian points, points on either side of the moon where the moon and Earth’s gravity balance perfectly.
