No, a suction cup works by forcing air out of the space between it and the surface it's on. No air = no suction.
A partial vacuum between the compressed suction cup and the flat surface.

When you stick a suction cup on a window you force the air out of the suction cup and you create a high pressure vaccume keeping the suction cup on the window.

You can improve suction it by moisturizing it's edges, this makes it stick to something longer and stronger.
I don't see any reason why it wouldn't.... all particles have different densities. unless rubber isn't dense enough to block the impossible zero density of outer-space. 0 is abstract not concrete. I would probably just make my suction cup out of metal and use a dyson vacuum to power it. lol <><><><> NO! A suction cup is held in place by the air OUTSIDE the cup pushing it against the surface. No air in space. No air, no push, no workee.

Cut a potato, rub the juice on the suction cup. This really does work. I don't know why.
A suction Cup will trap air behind itself which causes a partial vacuum. The negative pressure of trapped air or water causes it to keep in contact with the surface it is against.
I wouldn't want my last suction cup to slip, just as I reach the top of the window. The geckos have a very clever suction cup design of the soles of their feet.

In this procedure, the doctor uses a device called a vacuum extractor, placing a large rubber or plastic cup against the baby's head. A pump creates suction that gently pulls on the cup to ease the baby down the birth canal.

because you are pushing air out of the space between the window and the suction cup
mounting cup
I would guess injection molding. See the related link.
I am looking for a suction cup that uses a motor/ actuator instead of a air compressor. Check out "VERIBOR lever suction cups", I could remove the lever from this and attach an actuator to it, but that would be a very dirty solution. Is there any suction cups on the market that only require linear motion, built to be attached to an actuator? Or is there perhaps a module containing a suction cup attached to a linear actuator?
