Emissions from Artificial Object Re-entries
Welcome to our tracker for objects re-entering the atmosphere since the start of the megaconstellation era. Select a time window of interest to visualise 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 this page. Large ranges may be slow to load.
