how to get mun missions?

[1bdI]

So I have been playing career mode, and have completed 30 missions so far, with no failures. Reputation is around 170. I did all the stock reach certain orbit and speed missions, and orbited kerban, but I never got the option to go to Mun, which would be the next logical step. It was always the next step in previous versions. All I get a ferry vips, and test parts, with little tech gain, or payout.

Does it unlock after a certain rep threshold, or do I need to unlock certain techs to get it?

This is for version 1.0 btw

Thanks
