Context: Re-entry of Falcon 9 rocket stages has raised concerns about pollution in the upper atmosphere due to increasing space launches.
About Falcon 9 Re-entry & Atmospheric Impact:
- Falcon 9 is a reusable two-stage launch vehicle developed by SpaceX for satellite launches and missions.
- Rocket stages burn during re-entry, releasing metal particles (e.g., aluminium oxides) and combustion by-products.
- Affected Layers: Emissions occur mainly in the mesosphere and stratosphere, which have limited natural cleansing mechanisms.
- Ozone Impact: Particles may catalyse reactions that contribute to ozone layer depletion in the stratosphere.
- Key Facts:
- Stratosphere: Contains ozone layer (~15–35 km) that absorbs UV radiation.
- Mesosphere: Extends ~50–85 km, where most meteors burn up.
- Emerging Concern: With rapid growth in satellite launches and reusable rockets, upper atmospheric pollution is becoming a new environmental issue alongside space debris.
