How does utilizing lunar water ice for in situ resource utilization (ISRU) primarily benefit deep space missions heading towards Mars?
Answer
It dramatically lowers the cost and complexity by creating a lunar fuel depot
The core benefit of ISRU involving lunar water ice is transforming the Moon into a crucial waystation for deep space travel. By processing the ice into cryogenic rocket propellant ($ ext{H}_2$ and $ ext{O}_2$), missions heading onward, such as those targeting Mars, gain access to fuel that was manufactured locally. This circumvents the need to launch that propellant mass from Earth, which faces exponential cost increases due to the Earth's deep gravity well. Reducing this mass penalty drastically lowers overall mission cost and complexity, enabling spacecraft to carry more scientific instruments or increased supplies instead.
