Planned ‘megaconstellations’ of satellites could cause unforeseen harm to the ozone layer and climate systems. Global regulation is needed before it’s too late.

While rocket launches are increasing dramatically every year, it is still possible to mitigate any harmful effects on the ozone layer.
Rocket emissions in the upper atmosphere can damage the ozone layer but are neither measured nor regulated. It’s a policy gap we have to close if the space industry is to grow sustainably.
When the meteor exploded into pieces above New Zealand, it produced a shock wave strong enough to be picked up by earthquake seismometers. But any fragments have likely dropped into the ocean.
Discovery of many icy worlds helps unravel the solar system’s history.
It turns out that a common physical process called diffusion can explain the orbits of faraway minor planets – no need for a Planet Nine.
