Space shooters with horizontal scrolling starscapes are a staple in the app store just as they have been on every other game system. They also make for a great way to learn game development.
Ray Wenderlich has just released an excellent tutorial on how to create a side scrolling space shooter with Cocos2D.
In the tutorial you’ll learn how to set up Cocos2D, add in the game resources, create an accelerometer controlled player ship, a scrolling background, collisions, sound effects, and more.
You can find the tutorial here:

Ray has now expanded on the tutorial and created an extended Space Game Starter Kit with over 150 pages of his Cocos2D knowledge.
A great tutorial for anyone new to Cocos2D or just looking to create a side scrolling game.
