3. What is In Situ Resource Utilization (ISRU) in space?ISRU means using rocks, ice, and gases that are already on the Moon, Mars, or asteroids instead of bringing everything from Earth. It helps astronauts build homes and make food and fuel right where they are.
4. Why is ISRU important for space missions?It cuts the cost and weight of trips to space because we don't have to carry heavy supplies from Earth. ISRU also lets people stay longer and work more on other planets.
