There&#x27;s been no detailed presentation of the whole Mars architecture; Musk has promised to present at least an overview this September at the International Astronautical Conference.<p>In the meantime, it&#x27;s known that there&#x27;s a high-performance methane-fueled engine in development as part of the project (&quot;Raptor&quot;), with some component tests already underway at test facilities, and several dropped hints about components (including rockets substantially more powerful than the Saturn V used for Apollo lunar missions), but not enough publicly released to determine much about how operations would work.
