Spaceflight 🚀<p>The management of common pool resources depends crucially on the existence and effectiveness of the <a href="https://spacey.space/tags/rules" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>rules</span></a> and institutions to govern their use.<br>For <a href="https://spacey.space/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>space</span></a> activities, this translates into human activities potentially littering Earth’s orbits beyond sustainable limits, creating <a href="https://spacey.space/tags/SpaceDebris" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SpaceDebris</span></a> that could reduce the value of space activities by increasing the risk of damaging collisions 💥 and requiring mitigation actions. <a href="https://www.oecd.org/content/dam/oecd/en/publications/reports/2020/04/space-sustainability_a2d8e17f/a339de43-en.pdf" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">oecd.org/content/dam/oecd/en/p</span><span class="invisible">ublications/reports/2020/04/space-sustainability_a2d8e17f/a339de43-en.pdf</span></a></p><p><a href="https://spacey.space/tags/OECD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OECD</span></a> <a href="https://spacey.space/tags/SpaceRegulation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SpaceRegulation</span></a> <a href="https://spacey.space/tags/sustainability" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>sustainability</span></a></p>
Spaceflight 🚀<p>Uncontrolled reentries of space objects create a collision 💥 risk with aircraft ✈️ in flight. The highest-density regions have a 0.8% chance per year of being affected.
