3D-printing a lunar base

Published on Nov 6, 2014

Could astronauts one day be printing rather than building a base on the Moon? In 2013 ESA, working with industrial partners, proved that 3D printing using lunar material was feasible in principle. Since then, work continues to investigate the technique. The shielding against radiation provided by a 3D-printed block of simulated lunar regolith was measured, providing important inputs for next-stage designs... Soon the Agency is due to investigate another lunar 3D printing method, harnessing concentrated sunlight to melt regolith rather than using a binding liquid.

But how might lunar 3D printing one day be used in practice? Foster+Partners, contributing architectural concepts for the original study, put together this outline of a hypothetical mission to 3D-print an entire a lunar base, illustrating the design factors that steered them in their work. The rim of Shackleton Crater at the lunar south pole was chosen for the base location. The Moon’s rotation is such that the Sun only grazes its poles at low angles. The result is a near-constant ‘peak of eternal light’ along the rim of Shackleton Crater, beside regions of permanent shadow. Building in the vicinity of such a site would offer plentiful solar power, and relief from the extremes of heat and cold found across the rest of the Moon.

In reality any lunar base remains firmly on the drawing board, but each small step forward in research makes future lunar colonisation a little more feasible. In October 2014 more than 350 experts came together for a two-day Additive Manufacturing for Space Applications workshop at ESA’s ESTEC technical centre in Noordwijk, the Netherlands. They discussed the potential of 3D printing – also known as Additive Manufacturing – to transform the way the space industry operates and begin preparing common standards for its use.
 

Moon village

Almost 50 years since man first walked on the lunar surface, the head of the European Space Agency explains his vision for living and working on the Moon.

Johann-Dietrich Woerner believes the next giant leap for humankind could be an international collaboration of space faring nations in the form of a Moon village. This village would be a permanent lunar base for science, business, tourism or even mining.

Woerner explains how using the Moon’s own natural resources could help build and sustain a base by 3D printing a structure or building element. Robotic rovers could inflate protective domes for astronauts. He also discusses the potential hazards of living on the Moon as well as the possible locations of he lunar base and the advantages of a new global space project.
