Orbital dynamics, particularly in the context of lunar missions, encompasses the study of trajectories, stability and long‐term behaviour of spacecraft in the Moon’s gravitational field. Recent ...

It provides a dynamic, time-resolved view of planetary transformation, a missing link between young inflated worlds and the compact sub-Neptunes that populate the galaxy.

Fig. 1. Locations of samples returned from the Moon. Model ages of mare deposits [1] were based on superposed crater densities and the Neukum crater chronology [23]. The Moon had a much higher impact ...

Electrons inherently carry both spin and orbital angular momentum (i.e., properties that help to understand the rotating motions and behavior of particles). While some physicists and engineers have ...
