Satellite

The world’s longest quantum communications link has been set up between China and South Africa, spanning a record-breaking 12,900 km (8,015 miles). The connection takes advantage of quantum physics for “unbreakable” encryption.

The US Space Force has a contract worth up to US$60 million to develop and fly a kind-of aircraft carrier in space. No, it's not the result of a major typo. It's intended as a way to station space vehicles to quickly counter orbital threats.

The first satellite in a constellation designed specifically to locate wildfires early and precisely anywhere on the planet has now reached Earth's orbit, and it could forever change how we tackle unplanned infernos.

Dark matter is thought to outnumber regular matter by a factor of five to one – so why can’t we find the stuff? A new study proposes looking for it from space, using a satellite containing a levitating piece of graphite and a laser.

Starlink isn't the only American company to offer direct-to-cell satellite connectivity. AST SpaceMobile has been at it for years and was the very first company in the world to "phone home" from space. Now it's looking to provide 100% coverage of the US.

If you've ever found yourself in a dead zone, maybe you find solace in the quiet. Or maybe you've found yourself in an emergency and help is not coming. Either way, the ability to connect if and when you need to has its merits.

If you're an avid outdoorsperson who explores nature with their dogs, the Satellai tracker could keep your pooch safe in the wilderness. This solar-powered gadget can beam your dog's location straight to your phone using satellite connectivity.

Known for its budget Android phones, HMD has launched a potentially life-saving product for adventurers. Its OffGrid accessory pairs with any smartphone and enables texting via satellite networks – so you can reach people from the middle of nowhere.

SpaceX has just launched 20 of its Starlink satellites up into Earth's orbit, enabling direct-to-cellphone connectivity anywhere on the planet. That completes the constellation's first orbital shell, following a test of six satellites back in January.

One picture taken every day of the year starting September 2023 through to September 2024 provides a pretty fascinating perspective of the twilight zone transit due to the Earth's 23.5-degree axial tilt as it orbits around the Sun.

The most abundant metal known to man is iron. It's everywhere. Not just on Earth, but in space as well. Astro engineers have just figured out how to use iron – or nearly any metal for that matter – as plasma rocket fuel.

Star Catcher Industries has secured US$12.25 million in seed funding for its ambitious plan to build the first “space-based energy grid.” A network of satellites would gather and concentrate solar energy and beam it to other satellites in orbit.
