Our Solar System
In principle the relentless pull of gravity can amplify these small deviations until orbits migrate, cross, or otherwise go haywire. Newton concluded that God must step in from time to time to fix ...
Zero Gravity Explained: Where & When Does It Exist?
If there's one thing everybody knows about space, it's that there's no gravity once you leave the Earth's atmosphere. We all ...
Laser Precision Unlocks Secrets of Earth’s Gravity and Space Junk
Scientists are using laser-based tracking and gravity data to improve how we monitor both satellites and space debris. By blending these methods, they can now predict orbits more precisely and gather ...
As we await the Beaver Moon, NASA reminds us ‘we’re pushing' the moon away
The noteworthy report highlighted that because our planet and the Moon interact through tides, the natural satellite is ...

Geosynchronous Orbits
One application of the law of gravity is to figure out how to put a satellite into orbit so that it remains in the same position relative to ground all the time. A satellite in such a position can be ...
Launching mass from the moon helped by lunar gravity anomalies
Placing a mass driver on the moon has long been a dream of space exploration enthusiasts. It would open up so many ...
