What is the purpose of rockets making white smoke lines all over the sky?

i often see rockets making white lines all over the sky from their tails with smoke. i wonder what is the purpose behind it.

Are you sure those are really rockets? There are not that many launched, you know, and the tend to go up quite quickly so unless you are down range from a rocket launch pad, you probably never seen a rocket.

I tend to have a hunch that what you are talking about can be contrails from high altitude airliners. If this is so, and then they can be in all directions (while rockets are essentially launched towards the east to get an extra nude from the earth’s rotation) this is not smoke, it is just the engine exhaust, a mix of carbon dioxide and water vapor from the combustion of hydrocarbon fuel, that cools in the very chilly air at those altitude (10000 m and above). The ice crystals form and look just like a cloud that can dissipate at varying rate depending on how humid it is up there.
