Space Environmentalism<p>"With the rapid expansion of commercial space flight, thousands of satellites are being launched each year. Yet few owners have plans to remove them from orbit in a controlled way. Everyone, everywhere — on Earth’s surface, flying in aeroplanes, as well as in space — is increasingly at risk from these projectiles. Space-faring nations and companies must urgently address this threat."</p><p><a href="https://www.nature.com/articles/d41586-025-00797-7" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">nature.com/articles/d41586-025</span><span class="invisible">-00797-7</span></a></p><p><a href="https://mastodon.social/tags/SpaceEnvironment" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SpaceEnvironment</span></a> <a href="https://mastodon.social/tags/SpaceEnvironmentalism" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SpaceEnvironmentalism</span></a> <a href="https://mastodon.social/tags/SpaceDebris" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SpaceDebris</span></a> <a href="https://mastodon.social/tags/Space" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Space</span></a> <a href="https://mastodon.social/tags/SpacePolicy" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SpacePolicy</span></a></p>
