Real life missions

The high level of realism in Kerbal Space Program allows to recreate historical, current and future missions of human spaceflight. These missions start simple and become gradually more complex, so they are a great way to learn KSP. For a logical and progressive list of missions, goals, and milestones that may or may not have tutorials linked, check out the Campaigns article to get ideas in planning your own space program.

Sputnik 1 - first satellite in orbit
Vostok 1 - first human spaceflight
Gemini 6A & 7 First orbital rendezvous
Luna 9 - First soft landing of a probe on the moon
Apollo 11 - First human moon landing
Apollo 15 - First moon buggy.
Salyut programme - First space stations of any kind
Deep Impact - first look into a Comet.
International Space Station - Series of missions for the current space station.

Creating New Tutorials

To create your own tutorial, start with Tutorial:Template. When adding to the Category:Tutorials add the name of the tutorial (like in the template) to sort the pages without the prefix Tutorial:.

Note to tutorial writers: These are supposed to be tutorials. Think "Orbits for Dummies." If you're going to explain intricate details (including math!), consider marking your tutorial "Advanced".
