But SpaceX isn't just developing a rocket. They are developing a FLEET of rockets so that each rocket will be far less expensive than the Saturn 5 Moon rocket or the fleet of five complete Space Shuttle systems. And not only are they developing a fleet, but they will develop up to 10 variants of Starship in order to make a complete system of vehicles.

These variants, in order, are:
   1) The Super Heavy booster
   2) The Starlink dispenser
   3) The LEO Cargo Vehicle
   4) The propellant Tanker
   5) The Propellant Depot
   6) The Lunar Cargo Vehicle
   7) The Mars Cargo Vehicle
   8) The Lunar Crew Vehicle
   9) The Mars Crew Vehicle and finally
   10) The point-to-point Starship taking peole from, say, Los Angeles to Shanghai.

Jeff Bezos' company, Blue Origin, has developed hydrolox engines perfect for this Earth-Moon system. Using their nomenclature, we propose a reusable ferry which we call the "New Eagle". On their New Glenn booster, the New Eagle would to launched to LEO to meet up with a propellant depot variant. Propellant would be transfered to the New Eagle where it would then be able to deliver its full 45 metric tons, one-way, to the lunar surface. Then, telerobots would have harvested the polar ice and electrolyzed it into propellant. That propellant would be refill the now-empty New Eagle. It would then blast off the lunar surface to an Earth-Moon gravitational balance point where it would be able to dock with an retrieve with 45 tons of cargo or more than 45 passengers and ferry them back to the lunar surface.

Our model stands at about four feet in height which is close to the size of the grid fin on the Falcon 9. BUT, the height of the grid fin on Starship is about 16 feet, so four times as tall. As we make improvements and secure a permanent, outdoor display location, we hope to construct a grid fin out of metal that is the full 16 feet high. That would be amazing!

This is a question that is getting a lot of attention and there are many good ideas. One unique idea that the Space Development Network has come up with would be to land once at a regional space port location and unload two tarps. The inner tarp would have ceramics attached that could stand up against the rocket blast. Further out, an o-shaped tarp would be thin and simply keep the exhaust from interacting with the dirt. Robots would use ground anchors to firmly secure it to the ground so that it wouldn't be blown away. This would be a quick and simple way to establish a landing pad. Then, compacted dirt roads would allow the cargo and crew to be driven to the base perhaps 5 to 10 kilometers away from the regional space port.
