When you look at an astronaut floating outside the International Space Station, you aren't just looking at a person in a high-tech jumpsuit. You're looking at a human-shaped spacecraft. Honestly, that’s the only way to wrap your head around the price. If you think your designer winter coat was a splurge, wait until you see the invoice for a NASA Extravehicular Mobility Unit (EMU).
How much does it actually cost? Well, it’s complicated.
Back in 1974, a single NASA spacesuit cost between $15 million and $22 million. Adjust that for 2026 inflation, and you’re looking at roughly $150 million per suit. But here’s the kicker: NASA is currently moving toward a service-based model where the total contracts for new suits—the kind that will walk on the moon during the Artemis missions—have a ceiling of $3.5 billion.
Why the Cost of a Spacesuit Is So High
Space is actively trying to kill you. It’s a vacuum. It’s freezing. It’s boiling. It’s filled with tiny pieces of dust traveling at 18,000 miles per hour. To keep a human alive in that mess, a spacesuit has to be more than "clothing."
It’s an engineering marvel with over a dozen layers.
Inside, there's a cooling garment made of 300 feet of tubing that circulates chilled water to keep the astronaut from overheating (body heat has nowhere to go in a vacuum). Then there's the pressure bladder, the restraint layer, and the outer "Thermal Micrometeoroid Garment." This outer shell uses materials like Kevlar and Nomex to stop space pebbles from puncturing the suit. If a suit gets a hole the size of a pea, the mission—and the life—is over.

The "Billion Dollar" Misconception
You might have heard the headline that NASA's new suits cost $1 billion each. That’s a bit of a stretch, but only slightly. A 2021 report from the NASA Office of Inspector General (OIG) pointed out that the agency had already spent $420 million on suit development and would likely spend over $1 billion by the time two flight-ready suits were actually finished.
Basically, you’re paying for the R&D, not just the fabric.
New Players: Axiom Space and Collins Aerospace
NASA realized they couldn't keep building these things in-house forever. They pivoted. They decided to "rent" suits instead of owning them. In 2022, NASA awarded contracts to Axiom Space and Collins Aerospace to develop the next generation of gear.
- Axiom Space got a $228 million task order specifically for the Artemis III moon landing suits.
- Collins Aerospace was working on a $97.2 million contract for ISS suits, though they actually mutually agreed with NASA to "descope" (which is space-speak for "cancel") their part of the project in 2024 because it was taking too long and costing too much.
This shift to private companies is supposed to drive the cost of a spacesuit down, sort of like how SpaceX lowered the price of getting into orbit. Speaking of SpaceX, their approach is radically different. Their EVA suits—debuted during the Polaris Dawn mission—are way slimmer and look like something out of a movie. While SpaceX hasn't released a "per suit" price tag, the philosophy is mass production. NASA builds five suits; SpaceX wants to build hundreds.
Comparing the Eras
The price of exploration has never been stable. Look at how the numbers have shifted:

- Apollo Era: In the 1960s, an ILC Dover suit cost about $75,000 to $100,000. In today's money, that's roughly $670,000. Surprisingly cheap, right? But those suits were "single-use" and custom-tailored for one guy.
- Shuttle Era (EMU): These are the iconic white suits we see today. They were built to last 15 years and be refurbished. The 1974 price of $15M-$22M seems high, but they were meant to be used dozens of times.
- Artemis Era (xEVAS): These are the high-definition, mobile, "walking" suits. Because they need to handle lunar dust (which is like ground-up glass), the development costs have skyrocketed.
The Parts That Break the Bank
If you want to know where the money goes, look at the gloves.
The gloves are the most complex part of the entire system. They have to be pressurized enough to keep the astronaut's blood from boiling, but flexible enough for them to pick up a wrench or a moon rock. Astronauts often complain of "fingernail delamination"—where their nails literally fall off because the pressure in the gloves is so intense during a long spacewalk. Engineering a glove that doesn't do that costs a fortune.
Then there's the Portable Life Support System (PLSS). This is the backpack. It's a miniature version of a life support system you'd find on a submarine or a space station. It regulates oxygen, scrubs out CO2, and manages the radio. It's essentially a $50 million backpack.
Can We Make Them Cheaper?
Maybe.
The goal for companies like Axiom is to create a modular suit. Instead of building a whole new suit for a 5-foot-tall woman and a 6-foot-tall man, you build "arms" and "legs" in different sizes that click into a standard torso. This "plug-and-play" architecture is the best bet for lowering the cost of a spacesuit in the 2030s.

Also, 3D printing is starting to play a role. Printing custom fitments or internal plastic components can shave off thousands of hours of manual labor. But for now, every stitch is still largely done by hand by highly specialized technicians. You can't just run these through a sewing machine in a factory.
What This Means for the Future
The high cost of a spacesuit is currently the biggest bottleneck for the "democratization" of space. If it costs $100 million just to step outside the airlock, we won't be seeing lunar colonies anytime soon.
However, as the private sector takes over, we are seeing a shift from "bespoke government hardware" to "commercial off-the-shelf services." It's a slow transition. Space is hard. It's unforgiving. And as of right now, you still get what you pay for. If you want a suit that guarantees you won't turn into a popsicle the second you leave the station, you're going to have to pay the "space tax."
Actionable Insights for Space Tech Enthusiasts:
- Track the xEVAS Task Orders: Watch for NASA's upcoming contract updates with Axiom Space. These documents reveal the true "price-per-mission" of modern gear.
- Monitor SpaceX Polaris Results: The data from the first commercial EVAs will prove if "cheaper" suits are actually viable for long-term lunar work.
- Look into ILC Dover: They remain the gold standard for soft-goods engineering. If you're interested in the materials science of space, that's where the real innovation happens.
