Atmospheric entry by spacecrafts have reached 3 % of all atmospheric entries by 2024, but are projected to increase to 40 %.<ref name="h473">{{cite | title=Burned-up satellites are polluting the atmosphere | publisher=American Association for the Advancement of Science (AAAS) | date=23 July 2024 | doi=10.1126/science.zub5l4y | page=}}</ref> The impact of spacecrafts burning up in the atmosphere during artificial atmospheric entry is different to meteors due to the spacecrafts' generally larger size and different composition. The atmospheric pollutants produced by artificial atmospheric burning-up have been traced in the atmosphere and identified as reacting and possibly negatively impacting the composition of the atmosphere and particularly the [[ozone layer]].<ref name="h473"/>
