How do rockets keep from hitting debris when they enter space?
Space is big. Very big. Even with 10k or more bits of debris in orbit the odds of hitting any is very slim. I's actually a real concern. There's millions of tiny particles that can do catastrophic damage. Did you see what a tiny fleck of paint did to the space shuttle window? "There are more than 20,000 pieces of debris larger than a softball orbiting the Earth. They travel at speeds up to 17,500 mph, fast enough for a relatively small piece of orbital debris to damage a satellite or a spacecraft. There are 500,000 pieces of debris the size of a marble or larger. There are many millions of pieces of debris that are so small they can’t be tracked."

Is Earth going to get a ring like Saturn someday?
There was only 16 squadrons of RAF fighters that used 100 octane during the BoB.
The Fw190A could not fly with the outer cannon removed.
There was no Fw190A-8s flying with the JGs in 1945.

Another question to ponder:
Do directors and actors know when they are making a really crappy movie or are they somehow oblivious to it since they are not objective external observers? Upon making another Hammer Horror film, Christopher Lee complained that he doesn't have any lines. His long time coworker, Peter Cushing, retorted, "You're lucky, have you read the script?" Christopher Lambert, Micheal Ironside and Sean Connery agreed that Highlander 2 was stupid and just tried to out ham each other. Bruce Greenword and Aaron Eckhart delivered their lines professionally in "The Core" but pissed them laughing because the lines were so stupid.

Yes I know it is a concern but the question was "how do rockets keep from hitting debris" as if the debris was so dense that hitting debris was inevitable when launching a rocket into orbit, it isn't "that" bad. But if the chances are one in one thousand that is still something to consider the cost and/or lives involved.

Yes, Space is big. To quote someone who wrote a whole lot about Space:
"Space is big. You just won't believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space."
"From our orbital vantage point, we observe an earth without borders, full of peace, beauty and magnificence, and we pray that humanity as a whole can imagine a borderless world as we see it, and strive to live as one in peace."

Pointless OCDs are amusing.
You guys would go insane in my apartment. There's a wall switch that does nothing in my living room. Management doesn't even know what it was supposed to do and clipped the wires.
I like to imagine it turns a lamp on and off in the apartment below mine. Well it will drive you lot crazy in the UK where up = off It did drive me crazy. Moved from Australia to the UK (and then to the Czech Republic, where up is on also. I think). I have no idea what way light switches actually go, but I still want to wave my hand down the wall, hit the switch on the way, and have it turn on.

Replace them all with voice operated switches. Problem solved.  Points to Pooch for the Douglas Adams reference.
