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 ...

"In RTBP systems, Lagrange points between the two celestial bodies provide specific locations around which a spacecraft can orbit," explains Mingpei Lin, a member of an AIMR research team. "The ...

Reliably guiding and capturing optical waves is central to the functioning of various contemporary technologies, including communication and information processing systems. The most conventional ...

Paul M. Sutter is an astrophysicist at The Ohio State University, host of "Ask a Spaceman" and "Space Radio," and author of "Your Place in the Universe" (Prometheus Books, 2018). Sutter contributed ...

There are five gravitational balance points ("What are Lagrange points?" for those playing "Jeopardy!") for the Earth-sun system. A small satellite can orbit these points in a constant manner. The L1 ...

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 ...
