Another way to &quot;save on weight&quot; is to use the lowest-cost launch from Earth, and rendezvous in orbit. We&#x27;re going to know what the risk and cost of reusable Falcon 9 and Falcon Heavy is long before we&#x27;d start building this lunar base. A 75% reduction in SpaceX&#x27;s already low launch rates would be a big savings.<p>We even have experience launching fuel to ISS on the Russian and European unmanned supply ships.
