<p><b>New page</b></p><div>The Sabatier reaction creates methane (a possible fuel for launch vehicles and rovers) and water from hydrogen and carbon dioxide, at high temperature and elevated pressure, and in the presence of a catalyst (nickel, or better, ruthenium and alumina).<br />
<br />
<math>CO_2 + 4H_2 \to \limits^{300^\circ C} CH_4 + 2H_2 O</math><br />
<br />
For Marsian [[ISRU]], hydrogen could be imported from Earth, or produced by [[Water electrolysis|water electrolysis]]. Water could be collected from Marsian sources (''see'': [[Water on Mars]]), and also could be reused from the above reaction itself.<br />
