problem parts might include: - sending a ton of material to the moon subparts: - lifting a ton of material from the earth into space - transferring this material across space toward the moon - landing this material onto the moon the subparts could simplify away if we can teleport the material to the moon, or if there is some system managing them for us like a runaway apple-growing AI - growing an apple tree in a vacuum environment - growing an apple tree on a moonrocks surface - getting the apple tree to fruit with healthy apples subparts: - providing the tree with necessary nutrients - providing the tree with sufficient and appropriate sunlight, water, and gasses - convincing the apple tree that it is a mature tree and it is harvest time (plant hormones track temperature and light changes and lots of other stuff)
