We also chose the chemical composition of our new TerrAtmosphere. Mars’s current atmosphere is 96\% CO2, so it would be unrealistic to make the surface air breathable to humans using water vapor alone. Since we are estimating the minimum amount of energy required to terraform Mars, we decided to fix our TerrAtmosphere goal and calculate the additional mass and energy needed to obtain our desired TerrAtmosphere composition of 70\% C02, 26\% H20 vapor, and 4\% everything else, including nitrogen, oxygen, and argon. This is certainly a large amount of water vapor, but it would allow for precipitation and potentially better conditions for bringing terrestrial plants to Mars.   \begin{table}   \caption{Atmospheric Quantities}  \centering  \begin{tabular}{ c c c }  & Mars Today & Terra Mars \\   Atmospheric Chemical Composition & $^1$ 96\% CO$_2$, 1.93\% Ar, 1.89\% N$_2$, 0.145\% O$_2$ & $^3$ 70\% CO$_2$, 26\% H$_2$O vapor, 4\% other \\
