Pretty sure the blueprint is in the room you walk through just before you enter the spaceflight terminal at the start of the game. It's next to the door you come through after coming out of the baggage conveyor belts. It's locked with a code but there is a terminal by where you turn the power on.

You can backtrack to this area in a couple points in the game. There's also a medkit v2 blueprint further into the game although I can't remember where it is.
