Starlink already accounts for 40% of all the satellites ever launched, and each one releases harmful aluminum oxides when ...

Debris from rockets and satellites can fall back to Earth or collide with other objects, and wreckage that burns up can harm ...

Ozone, or O3, occurs in two forms in the atmosphere: what scientists call “good ozone” in the stratosphere, the layer of the atmosphere that sits 6 to 31 miles above the surface, and “bad ...

The ozone layer’s status today. In a report released in early 2023, scientists keeping track of the ozone layer noted that Earth's atmosphere is recovering.The ozone layer will be restored to ...

Earth’s protective ozone layer is slowly but noticeably healing at a pace that would restore the layer across much of the world by the 2040s, and would fully mend the hole over Antarctica in ...

The Ozone Layer: One Piece of an Important Puzzle. Earth’s atmosphere comprises multiple layers, each with its own role. Above the troposphere, Earth’s innermost layer (which contains Earth ...

The two chief chemicals that eat away at ozone are in lower levels in the atmosphere, Newman said. Chlorine levels are down 11.5% since they peaked in 1993, and bromine, which is more efficient at ...

Re-entry risks The rapid roll-out of satellite mega-constellations such as Starlink (photographed here over Carson National Forest, New Mexico) could pose a threat to Earth’s protective ozone layer.

Satellites’ impact on the ozone layer begins before they’re even in orbit, driven by the rocket trip to get them there. Kerosene used to power many launches burns more inefficiently the higher ...

The ozone layer is HEALING! Hole over Antarctica is smaller and has started later than expected this year, promising study reveals. The ozone hole is 18.48 million square kilometres smaller than ...

The Ozone Hole has been shrinking since 2006, but CFCs can persist in the atmosphere for a long time, and human-caused and natural events like volcanoes, wildfires, even rocket launches, have ...

But will scientists admit that they didn’t save the ozone layer? Background. Ozone is a gas made up of three oxygen atoms (O 3). Ninety percent of the ozone in the atmosphere is found in the ...
