    • Half a trillion dollars

      • A recent estimate of the cost of the first human mission to Mars suggests that it could cost “half a trillion dollars.” This estimate is consistent with most past estimates. A similar cost number can easily be derived using mass-cost estimating factors based on the International Space Station (ISS) and other experience.

    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...

  4. Apr 1, 2023 · In order to travel to Mars with NASA, it currently costs about $58 million per person. This includes the cost of the launch vehicle, the spacecraft, habitat, life support, and everything else needed to sustain a human on their approximately six-month journey.

  5. May 8, 2017 · Money spoke with Lee about the challenges facing Mars missions, and why it's important to launch Mars exploration missions despite them. At this point, what would it cost to send someone to Mars? Pascal Lee: The Apollo lunar landing program cost $24 billion in 1960s dollars over 10 years. That means NASA set aside 4 percent of U.S. GDP to do ...
