Journeying across the lunar landscape is a difficult task due to the treacherous terrain and low-gravity environment. The European Space Agency's 'PAVER' project plans to pave the Moon by melting regolith dust with concentrated light from a focused lens. The process under consideration is known as sintering, a technique that solidifies small particles into a cohesive mass without the need for liquefaction. Establishing a human settlement on the Moon is hamstrung by the need to take supplies with you - when any weight increases the power of the rocket needed to launch you from Earth. So it’s important to utilise anything that could be used as building material on the lunar surface. Researchers successfully demonstrated that the strength of the laser could align with the available lunar sunlight in a way that could fashion these tiles, with the aid of a relatively compact Fresnel lens spanning 2.37 square meters. Remarkably, these lunar tiles exhibited durability akin to that of concrete, rendering them eminently suitable for lunar road and landing pad construction.
