History[ edit ] As early asElon Musk stated a personal goal of eventually enabling human exploration and settlement of Mars[7] [8] although his personal public interest in Mars goes back at least to Rocket engine development is one of the longest subprocesses in the design of new rockets.

But those plans changed and, by Decemberthe plan to publicly release additional specifics had moved to On 27 Septemberat the 67th annual meeting of the International Astronautical CongressMusk unveiled substantial details of the design for the transport vehicles—including size, construction material, number and type of engines, thrust, cargo and passenger payload capabilities, on-orbit propellant-tanker refills, representative transit times, etc.

In addition, Musk championed a larger systemic visiona vision for a bottom-up emergent order of other interested parties—whether companies, individuals, or governments—to utilize the new and radically lower-cost transport infrastructure to build up a sustainable human civilization on Marspotentially, on numerous other locations around the Solar Systemby innovating and meeting the demand that such a growing venture would occasion.

The new system architecture has "evolved quite a bit" since the November articulation of the very large Interplanetary Transport System. A key driver of the new architecture is to make the new system useful for substantial Earth-orbit and cislunar launches so that the new system might pay for itselfin part, through economic spaceflight activities in the near-Earth space zone.

SpaceX's Mars objectives, and the specific mission architectures and launch vehicle designs that might be able to participate in parts of that architecture, have varied over the years, and only partial information has been publicly released.

However, once the architecture was unveiled in lateall launch vehicles, spacecraft, and ground infrastructure have shared several basic elements. Overview and major elements[ edit ] The SpaceX Mars architecture, first detailed publicly inconsists of a combination of several elements that are key—according to Musk—to making long-duration beyond Earth orbit BEO spaceflights possible by reducing the cost per ton delivered to Mars: Once again, the large propellant tanks in the integrated space vehicle are filled remotely.

Methalox was considered equivalent to one of the other primary options in terms of vehicle reusability, on-orbit propellant transfer, and appropriateness for super-heavy vehicles. They have developed more than one comprehensive set of booster and spacecraft designs that they believe would best achieve their Mars vision.

The current vehicle designs, unveiled in Septemberinclude four vehicles that each use what Musk called the internal codename "BFR": The heat shield material protecting the ship on descent is PICA 3. Entry g-forces at Mars are expected to be in order of 4—6 g during the descent. Just as for the spaceship, the tanker or cargo spacecraft serve as the upper stage of the ITS launch vehicle during the launch from Earth.

Once on orbit, a rendezvous operation will be effected with any ship that will be transiting on to a beyond Earth-orbit BEO destination, plumbing connections are made, and liquid methane and liquid oxygen propellants are transferred to the spaceship.

To fully fuel a BEO ship for a long-duration flight, it is expected that several tankers would be required to launch from Earth, carrying and transferring the propellant to fully load for the longer, high-energy journey.

Coupled with the Earth-orbit tank filling prior to the journey to Mars, and the fully reusable launch vehicles and spacecraft, all three elements are needed to reduce the transport cost by the multiple orders of magnitude that Musk sees as necessary to support sustainable colonization of Mars.

The plant is expected to be expanded over multiple synods as more equipment arrives, is installed, and placed into mostly autonomous production.

A chemical plant will process the raw materials by means of electrolysis and the Sabatier process to produce molecular oxygen O2 and methane CH4and then liquefy it to facilitate long-term storage and ultimate use.

Musk stated in September that the launch vehicle may launch from more than one site. Mission concepts[ edit ] Mars early missions[ edit ] Musk has indicated that the earliest SpaceX-sponsored missions would have a smaller crew and use much of the pressurized space for cargo.

If built, and if planned objectives are achieved, then the transport cost of getting material and people to space, and across the inner Solar Systemwill be reduced by several orders of magnitude.

SpaceX CEO Elon Musk is championing a much larger set of long-term Mars settlement objectives, ones that take advantage of these lower transport costs to go far beyond what the SpaceX company will build and that will ultimately involve many more economic actors —whether individual, company, or government—to build out the settlement over many decades.

The growth of such a system over decades cannot be planned in every detail, but is rather a complex adaptive system that will come about only as others make their own independent choices as to how they might, or might not, connect with the broader "system" of an incipient and later, growing Mars settlement.

Musk sees the new and radically lower-cost transport infrastructure facilitating the buildup of a bottom-up economic order of other interested parties—whether companies, individuals, or governments—who will innovate and supply the demand that such a growing venture would occasion.

You would need to mine and refine all of these different materials, in a much more difficult environment than Earth. There would be no trees growing.

There would be no oxygen or nitrogen that are just there. Excluding organic growth, if you could take people at a time, you would need 10, trips to get to a million people.

But you would also need a lot of cargo to support those people. In fact, your cargo to person ratio is going to be quite high. It would probably be 10 cargo trips for every human trip, so more liketrips. Thus, the private sector would have to see Mars as an attractive business environment. Musk is willing to pour his wealth into the project" but it will not be enough to build the colony he envisions.

The overview presentation on the Mars architecture given by Musk in September included concept slides outlining missions to the Saturnian moon Enceladusthe Jovian moon EuropaKuiper belt objects, a fuel depot on Pluto and even the uses to take payloads to the Oort Cloud. If fuel depots based on this design were put on asteroids or other areas around the Solar System, people could go anywhere they wanted just by planet or moon hopping.

Once that transport system is built, then there is a tremendous opportunity for anyone that wants to go to Mars to create something new or build a new planet. Funding[ edit ] The extensive development and manufacture of much of the space transport technology has been throughand is being privately funded by SpaceX.

The entire project is even possible only as a result of SpaceX multi-faceted approach focusing on the reduction of launch costs.Elon Musk and SpaceX have proposed the development of Mars transportation infrastructure in order to facilitate the eventual colonization of Mars. The design includes fully reusable launch vehicles, human-rated spacecraft, on-orbit propellant tankers, rapid-turnaround launch/landing mounts, and local production of rocket fuel on Mars via in situ resource utilization (ISRU).
