To my knowledge yes, You are only going to get missions you can accomplish. On the other note, I still think the Tech Tree needs a huge overhaul still is not that great or good or anything. I'm loving the contracts so far but not the new buttons UI, they are good but not great, I want to have both my Fuels and Electricity stuff open but at the same time the contracts open. dunno how to do it. Also if people feel the game is too easy for them, wow, good job, half of my rockets still crashes and burn. But I always go back to my Quicksave, there should be like a penalty or like an "Ironman mode" for the game, where you can't save at any point, just sometimes at some points.
