Mars is the planet closest to Earth. Many support that it may house humanity in the future. On the surface of Mars, sufficient resources are available to support life. Active studies are required to fundamentally comprehend the varied operating conditions and the major governing parameters involved in the growth of space colonization and supported atmospheric conditions. The existing legal framework of the Outer Space Treaty (OST), which was designed several decades ago, describes its goal of peaceful collaboration based on principles that we have not been able to uphold on Earth. It is vital to address the gaps in the legal system and ultimately deal with the mostly unanswered legal and regulatory questions. As interest in Martians colonisation missions from both government agencies and the private sector evolves, a workable solution that respects the essence of the OST and allows for limited sovereignty claims outside of protected habitation has been proposed.
