Latest Halo orbit Stories
The first of two ARTEMIS ("Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon's Interaction with the Sun") spacecraft is now in its lunar orbit. On June 22, ARTEMIS P1 began firing its thrusters to move out of its kidney-shaped "libration" orbit on one side of the moon, where it has been since January. Three successive maneuvers were used to kick the spacecraft out of its orbit and send it on a trajectory toward the moon. It continued on that path until June 27 at 10:04...
Lagrangian Point -- In Lagrangian mechanics, a Lagrangian point (or L-point) is one of five positions in space where the gravitational fields of two bodies of substantial but differing mass combine to form a point at which a third body of negligible mass would be stationary relative to the two bodies. Bodies at the L-point will not move relative to the parent bodies if they are not perturbed by other gravitational forces. They are sometimes also referred to as libration points. The...
