A defunct NASA satellite that launched 14 years ago to study Earth’s radiation belts is expected to crash back to the planet on Tuesday. The roughly 1,323-pound spacecraft, known as the Van Allen ...

NASA has successfully tested a system that allows satellites to navigate without GPS by using other spacecraft and debris as landmarks in orbit. In just three days, FALCON also improved the known ...

Researchers and government agencies are turning to artificial intelligence to solve one of spaceflight’s fastest-growing problems: tracking debris in the vast stretch between Earth and the Moon. With ...

Nearly half the manmade objects orbiting Earth are chunks of “uncontrollable” space junk — with just three countries fueling the problem and endangering future space travel, a shocking new study found ...

NASA's plan to crash the ISS back to Earth sounds simple, but the risks of falling space debris might be bigger than anyone expected.

To date, close to 30,000 satellites have been launched into Earth's orbit, leading to mounting concerns over the debris created when they collide. In a new analysis posted to the preprint server arXiv ...

Solar emissions exert 'drag' on space junk orbiting Earth. From historical measurements across a period of 36 years, researchers have now shown that space junk begins to fall down much faster once the ...

Each blue dot represents one of 16,500 active satellites. GPS navigation, banking transactions, communications, weather forecasting, emergency response systems, agriculture, aviation and national ...
