How many satellites orbit Earth?
The number of satellites orbiting our planet is rising fast, thanks to private "megaconstellations" that pose various threats to space exploration and astronomy. But how big has the problem already become?
Doomed Soviet spacecraft Kosmos 482 could hit Earth tonight. Here's when.
The failed Soviet spacecraft Kosmos 482 could crash to Earth overnight tonight after more than 50 years in the wrong orbit. Here are the latest predictions on the exact time of reentry, and where it could land.
Soviet spacecraft Kosmos 482 crashes back to Earth, disappearing into Indian Ocean after 53 years in orbit
The failed Soviet spacecraft Kosmos 482 has finally returned to Earth after 53 years in orbit. It disappeared into the Indian Ocean early Saturday morning.
Giant NASA science balloon completes trip around the world in 16 days
NASA's massive super-pressure balloon has completed a 16-day trip around the Southern Hemisphere — a milestone in high-altitude flight and atmospheric research.
Where will doomed Soviet spacecraft Kosmos 482 hit Earth? (Map)
Where will the failed Soviet spacecraft Kosmos 482 land when it crashes back to Earth in the coming week? Most major cities are in the potential crash zone — but the odds of a direct strike are extremely slim.
Doomed Soviet spacecraft tumbling toward Earth may already have its parachute ou
Newly published images suggest that an unknown structure is trailing behind the Kosmos 482 probe on its descent to Earth. It could be the doomed craft's parachute.
Doomed Soviet satellite from 1972 will tumble uncontrollably to Earth next week — and it could land almost anywhere
The lander section of the Kosmos 482 probe was launched in 1972 and designed to survive on Venus. Now it's due a fiery reentry to Earth.
China saves 2 doomed satellites with novel 'gravitational slingshot'
Chinese engineers have rescued two satellites that were stuck in the wrong orbit using a novel 'gravitational slingshot' method.
Can you burp in space?
Gravity plays a big role in burping, so could an astronaut burp in space?
US company to use giant spinning cannon to blast hundreds of pancake-like 'microsatellites' into space
Rocket start-up SpinLaunch wants to catapult hundreds of flattened "microsatellites" into space at once, using a cannon-like machine that accelerates objects by spinning them. The first orbital demonstration is scheduled for next year.
