The coming decades of space exploration hinge on a single, stubborn number: the 225 million kilometres between Earth and Mars ...

Former SpaceX engineer, Halen Mattison, and his startup, General Galactic, are looking to revolutionize rocket propulsion by turning water into rocket fuel. Their ambitious project, discussed in ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's ...

A former SpaceX engineer and his startup, General Galactic, are looking to put the concept of turning water into rocket fuel ...

A new radio survey reveals that the Milky Way’s magnetic field is intricate, widespread, and deeply connected to how the galaxy is organized.

General Galactic, co-founded by a former SpaceX engineer, aims to eventually build a propellant station on Mars.

General Galactic, cofounded by a former SpaceX engineer, plans to test its water-based propellant this fall. If successful, it could help usher in a new era of space travel. That's a big “if.” ...

Plasma propulsion transforms an inert propellant – often hydrogen – into plasma, a superheated mix of ions and electrons.

It may be possible to keep space exploration missions running longer and avoid spacecraft colliding with each other using a technique that harnesses magnetic fields to move satellites. Currently, most ...

Here’s what you’ll learn when you read this story: It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a stable magnetic field.

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life Earth’s magnetic field surrounds the planet, with ...

In the late 1800s, the French naturalist Camille Viguier proposed an idea that would be dismissed and forgotten for more than a century. He speculated that birds and other animals could navigate with ...
