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 ...

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 ...

When the Sun reaches higher levels of activity, junk drifting in low Earth orbit loses altitude at an increased rate — and for the first time, scientists have measured that increase and identified ...

Low Earth orbit is filling up. Alongside the working satellites that carry phone calls, weather data, and navigation signals, ...
