We can build really big things in space. Okay, not that big – yet. But we’ve packed the Earth’s lower orbit with about 5,000 satellites – some still functioning and some not. What if we could build a bigger, brighter satellite and put it into the Earth’s lower orbit? Something that would reflect so much sunlight that we’d never have to turn our lights on again. I’m talking about an artificial moon. How big could we possibly make it? And why would it be a bad idea to proceed with this space construction project?
