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...

As Mars orbits the Sun, it completes one rotation every 24.6 hours, which is very similar to one day on Earth (23.9 hours). Martian days are called sols – short for "solar day." A year on Mars lasts 669.6 sols, which is the same as 687 Earth days.
Oct 27, 2022 · Cost: $10,000 per pound. One of the biggest costs for any space mission comes with just trying to escape the gravitational pull of the Earth. And before you really begin to dream about massive ...
Jul 29, 2020 · Note that the Perseverance project’s cost is slightly higher here due to inflation-adjustments. The Viking project’s total was $7.1 billion but is divided into 2 “spacecraft” here for comparative purposes. All amounts adjusted to 2020 dollars via NASA’s New Start Index (NNSI).

Orbit: Elliptical and about 1.5 times farther from the Sun than Earth is (about 141.5 million miles or 227.7 million kilometers from the Sun, on average). Year: 1 Mars year (1 revolution about the Sun) takes 687 Earth days. Day: 1 Mars day or sol (1 rotation) is 1.027 longer than an Earth day (24 hours, 39 minutes, 35 seconds).

Oct 24, 2024 · Mars is the fourth planet from the Sun and one of the Earth’s two closest neighbors (the other one being Venus). How far is Mars from the Sun? Due to the high eccentricity of the Red Planet’s orbit, there’s a significant difference between Mars’ closest and farthest points from the Sun, which equal 206.6 million km (128.4 million miles) and 249.2 million km (154.9 million miles ...
