Mars orbiters have given astronomers an unexpected new vantage point on 3I/ATLAS, sharply tightening estimates of the ...

Orbital mechanics can be a bit counter-intuitive. We have to slow down an orbiting space craft to convert kinetic energy for gravitational energy. The orbital altitude is raised at its highest point ...

In this video, we explore the required velocity for an object to achieve a stable circular orbit around a planet. Learn about gravitational force, orbital mechanics, and how speed plays a crucial role ...

Tossing a bad guy into the Sun sounds simple enough, but orbital mechanics make it a far trickier task than you'd expect.

NASA has added interstellar comet 3I/ATLAS to its 'Eyes on the Solar System' app, allowing the public to track the object's ...

Annotation Designed to be used as a graduate student textbook and a ready reference for the busy professional, this third edition of "Orbital Mechanics is structured so that you can easily look up the ...

The great space race of the 20th century, which culminated in Neil Armstrong’s historic stroll across the surface of the moon, left an immeasurable impact on the modern world. It has inspired several ...

I have kind of a mental disconnect when trying to understand how orbits work. I know, from doing a lot of reading, that a spacecraft in orbit around a body like Earth can increase its orbital height ...

Mystery solved Changes in the Earth's orbit, not human activity, may be behind a subtle increase in methane levels 5000 years ago, according to new research. Over the last four glacial cycles (420,000 ...

Picture in your mind a big parking lot with 131 million cars on it. Now imagine that they are spread out over the entire Earth’s inhabited areas. Although still a large number, it is absolutely ...
