Visualization of the Sun-Earth Lagrange points. Orbital mechanics is a fun subject, as it involves a lot of seemingly empty space that’s nevertheless full of very real forces, all of which must be ...

Satellites and instruments placed at Lagrange points remain in a stable position because the gravitational forces from the Earth and sun balance each other, requiring only minimal energy for ...

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 ...

From the first satellite in orbit, to the first human in space, to the first steps on the moon, the United States government has always framed space exploration as a […] ...
