How Much Do Astronauts Get Paid? The Real Numbers Behind the Job
How much do astronauts get paid? The real numbers behind the job
The pay for an astronaut is not what most people expect. NASA astronauts start at roughly $102,000 a year, which puts them on par with a mid-level software engineer. There are no mission bonuses, no hazard pay, and no overtime — even if your planned 8-day mission turns into 286 days stuck on the International Space Station. That last part actually happened to Butch Wilmore and Suni Williams in 2024, and they received exactly $5 per day in extra compensation for the inconvenience.
This is a breakdown of what astronauts actually earn in 2026, how government pay compares to the growing commercial space sector, and why some of the most qualified people in the world still line up for a salary that tops out below $200,000.
NASA astronaut pay: the federal pay scale
NASA astronauts are federal employees paid under the General Schedule (GS) system. Every new astronaut candidate — regardless of whether they're a fighter pilot, surgeon, or PhD physicist — starts at GS-12 Step 1. Promotions follow the standard federal process, and most experienced astronauts land between GS-13 and GS-15.
Here's the 2025 pay table with Houston locality adjustment (Johnson Space Center is the duty station for all NASA astronauts):
The GS-15 Step 10 rate is capped at $195,200, which is the Executive Schedule Level IV ceiling. No matter how many spacewalks you complete or how critical your mission, your base pay cannot exceed that number.
Within each grade, there are 10 steps. Step increases happen automatically — every year for Steps 1-3, every two years for Steps 4-6, and every three years for Steps 7-10. A new astronaut reaching GS-13 after two years of training and then climbing to Step 10 would take about 18 years total.
The Houston locality adjustment adds roughly 35% to the base pay table, which is why these numbers look higher than the national GS rates you'll find on OPM's website. NASA astronauts are stationed at Johnson Space Center in Houston, and the locality rate applies regardless of whether they're physically in Houston, at Kennedy Space Center for launch prep, or training in Star City, Russia.
What astronauts actually take home
Beyond base salary, NASA astronauts receive the standard federal benefits package. This includes:
- FERS pension — a defined-benefit retirement plan based on years of service and highest 3-year average salary
- Thrift Savings Plan (TSP) — the federal 401(k) equivalent with up to 5% employer matching
- Federal health insurance — FEHB covers medical, dental, and vision for the employee and family
- Life insurance — Federal Employees' Group Life Insurance (FEGLI)
- Paid leave — 13-26 days annual leave depending on years of service, plus 13 sick days
There's also that infamous $5 per day incidental payment while on official travel orders — which includes time spent in space. For a 6-month ISS rotation, that works out to roughly $900 in extra pay. When Williams and Wilmore were stuck aboard for 286 days during their extended Boeing Starliner mission, their incidental pay totaled about $1,430. Their regular salary for the roughly 9-month stay was estimated at $125,000-$163,000 total, with no overtime or additional compensation.
Astronauts are salaried exempt federal employees. Whether they work 40 hours in a week or 100, whether they're on the ground or orbiting Earth at 17,500 mph, the paycheck is the same. There is no overtime, no flight pay, and no mission-completion bonus in NASA's compensation structure.
Commercial astronaut pay: how SpaceX and others compare
The commercial space sector has started to change the astronaut compensation landscape, though "astronaut" means something different at a private company.
SpaceX doesn't publicly disclose astronaut-specific salaries, but Glassdoor data and industry reporting suggest a range of $100,000 to $250,000 per year for crew-related roles, with an average around $151,000. Senior test pilots and mission specialists reportedly earn up to $277,000. Stock options in a company valued at approximately $800 billion add significant upside — something NASA's GS pay scale can never match.
Axiom Space employs a small number of professional astronauts, including former NASA veterans like Peggy Whitson and Michael Lopez-Alegria. Their salaries aren't public, but the real number that matters at Axiom is the seat price: approximately $55 million per seat for private astronaut missions to the ISS, with some nations paying up to $70 million. That figure covers 15 weeks of training, transport, and an orbital stay.
| Employer | Salary Range | Bonuses/Equity | Benefits |
|---|---|---|---|
| NASA | $102K–$195K | None | FERS pension, TSP, FEHB |
| SpaceX (est.) | $100K–$277K | Stock options | 401(k), health, equity |
| Axiom (seat cost) | Undisclosed | N/A | N/A |
The trade-off is real. NASA pays less, but offers ironclad job security, a pension, and the prestige of wearing the NASA patch. Commercial companies offer higher ceilings, equity, and faster pace — but with longer work hours and less stability.
International astronaut salaries
If you're looking at the pay for an astronaut outside the United States, the numbers drop significantly in most cases.
ESA (European Space Agency) uses an A-grade system. Astronauts progress from A2 (recruit) to A4 (post-first-flight), with base salaries ranging from roughly €60,000 to €108,000 per year. Expatriation allowances and housing benefits can push total compensation higher, but the base figures are well below NASA equivalents.
JAXA (Japan) pays astronauts as high-ranking government employees, with estimated ranges of $60,000 to $120,000 per year. Exact figures aren't publicly disclosed.
CSA (Canada) has published salary bands between CAD $89,100 and CAD $174,000, which translates to roughly $65,000-$127,000 USD. The Canadian Space Agency employs very few active astronauts.
The bottom line: NASA pays the best among government space agencies, by a comfortable margin. But even NASA salaries are modest relative to what the private sector offers engineers and pilots with the same credentials.
How astronauts are selected (and why pay doesn't matter)
The acceptance rate for NASA's astronaut program makes every other selective institution look easy. The 2017 class received 18,300 applications and selected 12. That's a 0.07% acceptance rate — compared to Harvard's roughly 4%.
| Class | Year | Applications | Selected | Rate |
|---|---|---|---|---|
| Group 21 | 2013 | 6,300+ | 8 | 0.13% |
| Group 22 | 2017 | 18,300+ | 12 | 0.07% |
| Group 23 | 2021 | 12,000+ | 10 | 0.08% |
| Group 24 | 2025 | 8,000+ | 10 | 0.13% |
The 2025 class was notable for being the first where women outnumber men (6 women, 4 men), and it included a former SpaceX launch director — a sign that the commercial-to-government pipeline is now flowing both ways.
Nobody applies to become a NASA astronaut for the money. The people in the candidate pool are military test pilots, emergency physicians, nuclear engineers, and astrophysicists — all of whom could earn more in the private sector. They apply because the job itself is irreplaceable.
If you're interested in the astronaut path, the engineering and science roles that build flight experience are the real entry point. NASA currently has 19 active job listings across its centers, including aerospace engineering roles at Johnson Space Center starting around $123,000.
The corps size problem
As of late 2025, NASA's active astronaut corps stands at approximately 44 members — one of the smallest rosters in over two decades. For context, the corps peaked at nearly 150 during the Space Shuttle era.
A NASA Inspector General report (IG-22-007) flagged that the corps may be too small to support upcoming Artemis lunar missions, ISS commitments, and commercial crew partnerships simultaneously. The safety margin for unexpected attrition was quietly reduced from 25% to 15% after 2014, with no documented justification.
The 10 new candidates announced in September 2025 will help, but they need roughly two years of training before becoming flight-eligible. Between retirements, departures to the private sector, and increasing mission demand, retention is becoming a real issue — and the federal pay cap is part of the reason.
When SpaceX can offer $200K+ with equity to the same caliber of engineer-pilot that NASA pays $170K with a pension, the math gets harder to justify for anyone who isn't deeply motivated by the NASA mission itself.
Getting into the industry without the astronaut title
Most people searching for the pay for an astronaut are really asking a broader question: what does it pay to work in human spaceflight? The answer depends on the role and employer.

Frequently asked questions
How much does an astronaut make per year? NASA astronauts earn between $102,203 and $195,200 per year based on GS grade and step, with Houston locality pay included. The median for experienced astronauts falls around $150,000-$165,000. Commercial astronaut roles at companies like SpaceX may pay higher, with estimates reaching $250,000+ for senior positions.
Do astronauts get paid while in space? Yes — they receive their regular salary. There is no additional flight pay or hazard pay. The only extra compensation is a $5 per day incidental allowance while on travel orders, which includes time aboard the ISS.
How much do astronauts make per hour? Based on a GS-13 Step 5 salary of approximately $140,000 and a standard 2,087-hour federal work year, that's roughly $67 per hour. In practice, astronauts work far more than 40 hours per week during training and missions, making the effective hourly rate considerably lower.
Is astronaut a well-paying job? Relative to the qualifications required and the risk involved, astronaut pay is modest. A GS-15 astronaut earns less than many senior engineers at aerospace companies. But the federal benefits package (pension, TSP matching, health insurance) adds significant value, and the job itself offers experiences that no salary can buy.
How hard is it to become a NASA astronaut? Extremely hard. NASA's acceptance rate ranges from 0.07% to 0.13% depending on the year. The 2017 class accepted 12 from over 18,300 applicants. Minimum requirements include a STEM degree, 2+ years of related professional experience (or 1,000 hours pilot-in-command time), and passing the NASA long-duration spaceflight physical.
Do astronauts pay taxes? Yes. NASA astronauts are federal employees and pay federal, state, and local income taxes on their salary. There is no tax exemption for time spent in space. Texas has no state income tax, which is one financial advantage of being stationed at Johnson Space Center in Houston.
