Space junk returning to the Earth is introducing metal pollution to the pristine upper atmosphere as it burns up on re-entry, ...

This one event injected a staggering 10 times more lithium into the atmosphere than the typical daily amount.

When we look up at the night sky and see a satellite glide past, we might not consider climate change or the ozone layer. Space may feel separate from the environmental systems that sustain life on ...

Researchers have detected measurable traces left in the upper atmosphere when a rocket stage burns up, finding about ten times more lithium atoms than normal at around 96 kilometres, roughly 20 hours ...

The study highlights how letting rocket debris burn up in the atmosphere is not a consequence-free approach to orbital ...

NASA’s ESCAPADE mission studies how solar wind removed Mars’ atmosphere, using twin spacecraft to measure atmospheric escape, magnetosphere changes, and space weather impacts.

The recent study focuses on the amount of lithium left behind from a single rocket reentry. Previous studies have already shown that lithium, aluminum, copper, and lead left behind from the reentry of ...

More than 120 seismometers detected sonic booms from space debris and enabled its fall to be tracked with unprecedented ...

Some of the best views of Earth come from beyond our home planet, as recently captured by astronauts aboard the International Space Station (ISS). In late October, astronauts saw Earth covered in a ...

“We’ve known for a long time that space debris reentering the atmosphere produces sonic booms, exactly the same way as natural meteoroids or supersonic aircraft produce sonic booms,” said Benjamin ...
