The first of the two ARTEMIS spacecraft entered lunar orbit this morning. ARTEMIS was the first mission to orbit the moon's Lagrangian points and this is the first ever attempt to move from the Lagrangian into lunar orbit.
ARTEMIS Spacecraft Prepare for Lunar Orbit

It took one and a half years, over 90 orbit maneuvers, many gravitational boosts and little fuel to move two spacecraft from their orbits around Earth to their new home around the moon.
Dead Spacecraft Walking

Because they lie just outside Earth's magnetosphere, Lagrange points are excellent places to study the solar wind.
ARTEMIS Spacecraft Believed Struck by Object

Flight Dynamics data from THEMIS-B (one of the two ARTEMIS spacecraft) indicated that one of the electric field instrument spherical tip masses may have been struck by a meteoroid at 0605 UT on October 14.
ARTEMIS - The First Earth-Moon Libration Orbiter

NASA has achieved another first by placing the ARTEMIS-P1 spacecraft into a unique orbit behind the moon, but not actually orbiting the moon itself.
