   space.stackexchange.com › questions › 3409

   When you read these cost breakdowns, the actual rocket launches are generally not a huge portion - even if we assumed a manned mission would require 4 x BFR or 4 x SLS Block II, at something like 2 billion/launch, and a complete dress-rehearsal unmanned, that's $16 billion or so.

   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.

   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 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...

   How much does it cost to build the ISS?

   • Over its 20+ years in orbit, the international space station costs over $150 billion to develop, making it the most expensive thing ever built. Currently, it costs $88,000 to $164,000 per person per day to operate things. And with seven people on board the ISS, it costs around $616,000 to $1.2 million per day.

   How much did the US spend on the ISS?

   • In total, it calculated that the United States spent approximately $75 billion on the ISS through 2013: $43.7 billion for construction and program costs plus $30.7 billion for 37 shuttle launches. Another difficulty in calculating sunk costs, however, is when to begin counting the dollars spent.

   How much would a manned mission to Mars cost?

   • While a two-decade campaign to prepare a manned mission to Mars would certainly be expensive, it would cost nothing close to the $1 trillion figure that has sometimes been cited, the panel concluded. Instead the mission could be funded out of the current NASA budget, with allowances for inflation, along with contributions from other countries.

   How much will ISS operations cost a year?

   • Among its conclusions is that NASA’s estimate that ISS operations will cost $3-4 billion a year is overly optimistic especially because the cost of commercial crew services purchased from U.S. companies are expected to be higher than what NASA currently pays Russia.
