SpaceX Mars colonization program

The main element of this ambition is the plan to establish a self-sustained large scale settlement and colony on Mars, claiming self-determination under direct democracy.[16] The company's current plan was first formally proposed at the 2016 International Astronautical Congress alongside a fully-reusable launch vehicle, the Interplanetary Transport System.[6] SpaceX has been setting up since 2014 a facility called Starbase and more recently a factory called Starfactory on the previously populated and wildlife area Boca Chica (Texas) peninsula in the Rio Grande delta at the Gulf of Mexico,[19] partly justified by SpaceX with its colonial perspective,[20] to launch and build an in development fully reusable super heavy-lift launch vehicle with the name Starship.Aiming with its reusability to drastically reduce launch costs and scaled construction and swift maintenance between flights,[21]: 2 this has been the basis for SpaceX to advance its Mars ambitions and when operational will allow it to provide the necessary transportation capabilities for its colonial goals.[27] Methane was chosen for the Raptor engines because it is relatively inexpensive, produces a low amount of soot as compared to other hydrocarbons,[28] and can be created on Mars from carbon dioxide from the atmosphere and hydrogen via the Sabatier reaction.[33] SpaceX has stated on several occasions aspirational plans to build a crewed base on Mars for an extended surface presence, which it hopes will grow into a self-sufficient colony.[36] Equipment that would accompany the early groups would include "machines to produce fertilizer, methane and oxygen from Mars' atmospheric nitrogen and carbon dioxide and the planet's subsurface water ice" as well as construction materials to build transparent domes for crop growth.[46] Musk has stated in 2024 that in-situ resource utilization will be critical for establishing a self-sustaining colony, and that SpaceX plans to begin its efforts in advancing that field in "seven to nine years".Some experts, like Robert Zubrin, support the concept due to the prevalence of water ice in the form of permafrost and glaciers on Mars, as well as other resources like carbon dioxide and nitrogen.As of July 2019, SpaceX had not publicly detailed plans for the spacecraft's life-support systems, radiation protection, and in situ resource utilization, which are essential for space colonization.[62] Some of this has been introduced through the terms and services agreement for individual users of SpaceX's Starlink platform, stating the following: "the parties recognize Mars as a free planet and that no Earth-based government has authority or sovereignty over Martian activities".
