Did you spot there's a lever on top of the hatch? Where you met Piscilla?
There is a lever
But it is not working. Maybe it is connected to the engine. Is the engine running?
The engine is fueled up
Great! Pull the lever to lower the hanging metal tube. That is your key to open the huge door.
What should I do to the hanging metal tube?
You need to interact with it. But it is quite high. Use some longer range item to it.
What item should I use to the metal tube
Get the gun from Piscilla. ( Talk to Otis (Use the strange machine to make him appear) until he tells you that the laboratory is behind the huge imposing door. Talk to Piscilla until you get the gun. When you leave the cryo room they should follow you. )

Don won't enter the lab
Get yourself a deterrent. ( Pick up the liquid nitrogen spray in the cryo room. )
