The cost of a humans-Mars mission is estimated in the 100s of billions [ref. 13]. The costs are spread among the capabilities (see Figure 2), stemming from a design reference architecture that has not materially changed much in nearly 30 years.

document gives some previously estimated costs for a human mission to Mars, cites the costs of earlier human missions such as Apollo and the International Space Station (ISS), and then derives an independent cost estimate using historical data. The cost of life support for the Mars mission is discussed.
Some of the previous estimates of the cost for a human mission to Mars are cited. They are largely consistent.
In general, the best way to estimate costs is by direct analogy with the past costs of similar missions. Most of the estimates given here were made using cost estimation methods that are based on past mission data. NASA’s human relevant human missions are the International Space Station (ISS), space shuttle, and Apollo.
The cost of ISS life support is estimated as a guide to the cost of life support for Mars.
The cost of the Mars life support system could easily be the same or even more than that of the ISS system The ISS life support can provide for more than the three or four US crew on ISS, so it could be easily scaled down to one half the ISS size. On the other hand, a Mars mission will require two life support systems both able to support the full ...
The best and most realistic way to estimate project cost is by using comparisons to earlier similar projects. Professional cost estimating models use parametric cost estimating relationships, which relate cost to measurable cost drivers such as mass, number of systems produced, and technical difficulty. The estimates produced by comparison to pas...

At the dawn of the 21st century, NASA crafted four potential pathways to Mars human missions, [78] of which three included a Mars sample return as a prerequisite to human landing. [ 78 ] The rover Perseverance , which landed on Mars in 2021, is equipped with a device that allows it to collect rock samples to be returned at a later date by another mission. [ 79 ]
