How many current or near-future pressure suits are there for use in space in total?
I'm counting any current as at least flown in space once. IVAs are for use inside of a vehicle in the event of an emergency depressurization or similar event, EVAs are for use outside of a vehicle.

While Rory's answer is close, let me give a few additional details.

What are the requirements differences between Escape Suit and EVA Suit?
The main consideration is the lifetime. An escape suit only needs to function for maybe 10 minutes. While they do need some life support provided through launch, it can easily be disconnected if requi …

Would a duct tape spacesuit be practical?
First of all, the idea as proposed in the movie is pretty crazy. What they would more likely use is Kapton tape, which is a kind of space rated duct tape. It's yellow-brown, actually could hold an atm …
