Since 2017, the frequency and scale of rocket launches have surged, with 2,644 objects launched in 2023 compared to just 221 in 2016. Over 10,000 satellites orbit Earth, predominantly operated by SpaceX, which aims to expand its fleet to 40,000. While many launch-related effects are temporary, concerns persist regarding atmospheric pollution from rocket fuel combustion and debris re-entry incidents, which, though rare, can result in the harmless landing of large components. Atmospheric scientist Kostas Tsigaridis warns these combustion byproducts could have lasting effects on the upper atmosphere's chemistry.
The increase in rocket launches from 221 in 2016 to 2,644 in 2023 highlights the dramatic growth of satellite deployment, significantly impacting space and atmospheric dynamics.
While most space debris burns up upon re-entry, some larger components fall harmlessly to Earth, as evidenced by incidents in North Carolina and Florida.
Kostas Tsigaridis emphasizes that the combustion byproducts from rockets' ascent and re-entry pose significant concerns for the upper atmosphere, potentially altering its chemistry.
Elon Musk's SpaceX leads the satellite surge with plans to expand its fleet from 6,000 to 40,000, raising questions about space sustainability and debris management.
