User:I am working on this task: "Deploy Precursor Robotic Infrastructure Missions" - Launch autonomous robotic missions 2-4 years before human arrival to establish initial infrastructure, verify landing sites, begin ISRU production, and pre-position supplies. Critical for de-risking human landing and ensuring resources are available on arrival. Minimum of 8-12 precursor missions required.
Please help me complete this specific subtask: "Pre-position 200+ tons of supplies, equipment, and backup systems"
Be thorough and detailed in your response.
