Do rocket launches harm the ozone layer?
From time to time, people claim that chemicals released from some rockets, in particular NASA’s Space Shuttle’s Solid Rocket Boosters (SRBs), are responsible for a significant amount of damage to the ozone layer. Studies indicate that they have only a minute impact (less than seven-thousandths of one percent), both in absolute terms and relative to other chemical sources. It is much less than total ozone variability associated with volcanic activity and solar flares.
