The first artificial intelligence model trained entirely in orbit has turned a test satellite into a tiny, solar-powered data center, and it runs on a single Nvidia chip. By pushing a full training ...

There are about 15,000 satellites orbiting Earth. Most of them, like the International Space Station and the Hubble Telescope, reside in low Earth orbit, or LEO, which tops out at about 1,200 miles (2 ...

The Earth's liquid molten outer core, composed mostly of iron and nickel, exerts an electromagnetic field extending from the north and south pole that protects the planet from harmful solar particle ...

The sky will have a new cosmic visitor this fall: A second moon will drift into Earth’s orbit. Asteroid 2024 PT5 is poised to become a temporary mini moon of Earth, a phenomenon that will last for ...

Two BeiDou-3 satellites, once plagued by puzzling orbit errors, are now operating with newfound precision thanks to a breakthrough modeling strategy. Researchers discovered that standard models ...

Satellites in orbit would begin to collide in a matter of days if they lost manoeuvrability during a solar storm or other ...
