How many days do you think you can last? (The Last Colony)

Looks like I made my game a little too difficult. So I throw you all a challenge.
How many days do you think you can last? :D
The control is simple. You move the cargo ship using its thrusters and lock it when the guiding orb meets the dock. You undock the ship when it finishes unloading. The catch is, you need to operate up to 4 ships at a time.

If 12 keys for control is intimidating, try to transpose them onto the docking stations as they are. (Q, E, and R belong to station on the top left, A, D, and F belong to the one one bottom left.) If you don’t use qwerty keyboard, I am sorry :’(
So far, I know @pkenney reached 53 days, and a friend of mine lasted 60 days. How far can you survive?
