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. Using the same cost factors and life cycle cost estimating approach, the cost of the life support for the Mars mission could be two billion dollars or more. The cost to go to Mars is expected to be two or three times that of either Apollo, space shuttle, or ISS and could be as much as all three together.
