U.S. Chief of Space Operations Gen. Chance Saltzman said the exercise will send a "clear message" that Space Force is ...

Once we know all those parameters (called the orbital elements), we can mathematically define the associated ellipse. If we also know an asteroid’s position along its ellipse, ...

This course delves into the core principles of classical mechanics and celestial mechanics that describe and predict orbital trajectories. Key areas of study include the mathematical representation of ...

This won’t be U.S. Marines armed with laser weapons and transported via space ship a la “Moonraker,” but a broad array of terrestrial and orbital weapons are being eyed. The latest on Task ...

“We compare the orbital elements of 2024 YR4 with the near-earth asteroid population model and find that its most likely sources are resonances between the inner and central main belt. ...

Transform the orbital elements of any basic satellite into position and velocity information, which is recorded as {px pq, py pq, pz pq, vx pq, vy pq, vz pq}.
