Scientists warn satellite launches increase atmospheric pollution risks (opens in new tab)

Scientists are examining how rapid growth in space activity could affect the atmosphere, including emissions from launches and material released when spacecraft burn up during re-entry. NPR and other science coverage linked the issue to climate and ozone questions as researchers look for measurable chemical effects high above Earth. Falling orbital debris is drawing separate attention because some spacecraft components no longer fully disintegrate on the way down. Phys.org, WGN and Infobae de...
