i was just thinking... doesnt it hurt the ozone layer to launch rockets into outer space!?! dont you think all that smoke, fire and stuff would hurt it!?!

Environmental groups have recently voiced concern that exhaust from the space shuttle and other rockets could harm the protective ozone layer. But measurements taken by satellites after shuttle launches do not show any sign of stratospheric ozone destruction, atmospheric scientists report.
Solid-propellant motors used to loft some rockets pose a potential threat to the ozone layer because their exhaust contains chlorine, which in some forms can destroy ozone. Indeed, a scientific flight through a rocket's exahust plume in the 1970s detected a 40 percent decrease in ozone levels in the plume, reports Steven Aftergood of the Washington, D.C.-based American Federation of Scientists in the Sept. 20 JOURNAL Of GEOPHYSICAL RESEARCH. Aftergood suggests that launches may produce local ozone "holes" that persist for several hours.
In the same journal, Richard McPeters of NASA's Goddard Space Flight Center in Greenbelt, Md., and his colleagues respond to Aftergood's comments by examining satellite measurements of ozone in the shuttle launch area. They find no detectable ozone decrease after several launches.

The wholes in the ozone are a natural occurring event. In about 7 to Ten years they will close to what is considered to be normal. The ozone is affected more by the number of sun spots than any thing that man can inflict.

Ozone depletion is caused by specific chemicals (particularly chlorine and bromine) that act as catalysts in a reaction that destroys ozone molecules. Rocket exhaust typically does not contain any of those chemicals, but even if it did, pollution from rockets is miniscule compared to other sources. As impressive as rockets are, there are very few of them.

Yea, Those rockets poke holes in the Ozone everywhere they go through. This what Global warming all about, but, they not want you to know and blame it on other things that cost the consumer more money.
OK, well, maybe I'm wrong, but, it did sound good.

Rockets use mainly liquid hydrogen and liquid oxygen for fuel. All that "smoke" you see is actually water vapor and has no effect on the ozone.

IT does, but we can do research in outerspace that can reverse the efects of global warming and other ozone effects. so it does harm it, but all the cars and other man-made devices are A LOT A LOT A LOTTTT worse.

Not anymore then the toxic fumes we generate all day everyday here in our daily lives. Rockets are launched so infrequently that I would believe that the impact they create on the atmosphere is pretty small.

yes. maybe they can make rocket fuel out of ozone. can you make fuel out of ozone?

it really is what i do not comprehend. If peeps do not favor their bodies in heaven, why did he flow or shoot up in any respect? I purely ~ properly ~ I purely ~ hmmm ~ do not get it. became it theater? you comprehend ~ dramatic result? To contemplate slightly extra ~ what happened to the body? Did it purely evaporate someplace round sector 9 or is it nevertheless floating someplace? this kind of huge volume of unanswered questions.

not that I am classified to know about, maybe it is all a big cover-up.
burning hydrogen and oxygen creates water molecules by the way.
