The recent splashdown of the Artemis II mission, which saw four astronauts travel further from Earth than any humans in history and return safely, has been widely celebrated as a significant technical achievement. While undoubtedly a triumph for space exploration, this mission also underscores the accelerating pace of human ambition to establish a presence beyond our home planet, particularly on the Moon and Mars.
As these missions pave the way for what could become 'civilisational decisions' regarding humanity's future in space, a growing chorus of voices is arguing that the conversation needs to move beyond mere technical feasibility. Instead of solely asking 'what we can do,' experts are now pushing for a deeper public discussion on 'whether we should do it,' particularly concerning the potential transformation of celestial bodies like the Moon and Mars.
This call for public engagement comes from figures like Ben Bramble, who argues that the implications of such large-scale endeavours extend far beyond scientific and engineering challenges. The prospect of altering environments on other planets – often referred to as 'terraforming' – raises profound ethical, philosophical, and environmental questions that, it is argued, should not be decided by a select few.
The argument suggests that these decisions about humanity's role in the cosmos will have long-term consequences, shaping our relationship with space for generations to come. Therefore, a broad and inclusive public debate, rather than just expert consensus, is deemed essential to navigate these complex issues before irreversible steps are taken.
