Space suits!


I was watching a programe last night during which it was stated that space suits cost $12Million each!

$12Million!

Yikes, How???

What I mean to say is that, ultimatly, the cost of something is related to the amount of human effort (Man Hours) that go into aquiring/creating it.

Even if one were assuming $120/hr that is a 100,000 man hours per suit!

That is more than a working lifetime!

Now I know that you cannot afford to have any mistakes on a space suit. I also know that there is clever engineering involved and even special materials.

But $12 Million worth!

I think the cost is ultimately also a function of small (or no) batch sizes--how many space suits do you expect a particular manufacturer to make? How much special equipment is needed to sew the special (and tough) fabrics and rubber layers? How much precision tooling is needed to mill the seal races and ring bearings that give a spacesuit its flexibility. I've read somewhere that the most expensive single component of a spacesuit (atleast of US manufacture) is the gloves: each glove set must be made to a particular astronaut's hand dimensions. The cost of a set of gloves for a Space Shuttle Space Suit is in the 'hundreds of thousands of dollars.'

It is an interesting question, because this problem will need to be addressed when we have hundreds of people living and working in space...

I suspect that a dedicated manufacturing plant will be needed--and then standardize the main components, and fit those main components to a range of over garment sizes: the gloves will still likely to be custom built for each user--but once the whole process is 'assembly lined' I'm thinking the indivual production costs will go down. It's just the cost of the suit is reflected in the capital investment of the manufacturer--if it costs $75 million (just a WAG) to build the facility that expects to produce probably no more than 10 space suits--bam! I can see suits costing $12 million a piece. Now if a production facility costs $500 million to build, and is expected to produce 1000 space suits, I can see their individual costs dropping below $1 million a piece.

I was thinking about the gloves actually, and I was wondering why bother!

Trying to make a spacesuit "Glove" that would fit over an Astronauts hand and actually be usable is an almost impossibly dificult task.

I am not surprised that they cost a fortune.

Why not just make the arms  a bit longer and have external prosthetics manipulated by internal controlls (IYSWIM)

on your other note. there is the diference between set up (Inc R&D) costs and marginal production costs. I could see how full amortized costs might end up in the millions of dollars range, but not the marginal costs

I remember thinking some years ago that the cost and availability of space suits could well end up the most serious bottleneck in the expansion of manned space.

Hamilton Sundstrand has protested NASA's selection of a Houston company to supply the space agency's next-generation spacesuit.link


"The contract was awarded June 12 to Houston-based Oceaneering International, best known for providing deep-water services and products to the oil and gas industry."


It seems funny only one company was selected. Why weren't they both able to participate in the contract?? Was it a bidding process? Maybe if both companies participated costs might have been brought down.

Seems fishy to me...aren't you suppose to get input from as many qualified companies as possible that want to participate in a national space program?


I don't agree with giving only one company the contact unless it is absolutely warranted.

There are too many qualified good companies in the U.S. not to give them a chance at particpating in the national space program.

Yeah--I don't really know. Because the number of units is pretty small, the usual bidding process may have been circumvented...

On the other hand, a reasonably good competition ought to result in the best and lowest cost unit...

Is this still a prototype they're talking about--maybe one or two units for vac and field testing?

From what I understand suits are built for space EVA, Lunar, Mars etc.
In other words they are task, environment specific.smile
