Explore the physics behind traveling from the Earth to the Moon and discover where gravity effectively becomes zero. Learn how gravitational forces balance, why astronauts feel weightless, and how ...

Thanks to not-so-recent advances in technology, we can shoot just about anything into space, or at the very least into Earth's orbit. At first, we launched spy satellites during the Cold War, but once ...

This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.
