Emissions from Artificial Object Re-entries
Emissions tracker for objects re-entering the atmosphere since the start of the megaconstellation era. The Globe and Map views show the location and ID of each re-entry for the time windows, mission type, and object categories selected. Bars total the corresponding emissions and intact (unablated) mass.
For more information, see the FAQs at the bottom of the page.
Please select a date during 2020-2022 (2023-2024 will be released shortly). Large ranges may be slow to load.
