Lagrange points are locations around a two-body system where the gravitational forces of the two objects, in this case Earth and the Moon, are equal to the centrifugal force. This allows for a ...

Correction: An earlier version of this story erroneously stated that China’s Queqiao satellite was orbiting the Earth-Sun L2 Lagrange point. In fact, Queqiao orbits the Earth-Moon L2 Lagrange point, a ...

With doubts brewing about the feasibility of returning to the moon or aiming straight for Mars, another option has emerged for our next steps into space: gravitational “sweet spots” called ...

Advanced space travel relies on a fundamental understanding of the restricted three-body problem (RTBP), in which one of the three bodies—typically a spacecraft—is so small that its gravity doesn't ...
