Illustration of a paved highway and touchdown pad on the lunar floor

Lunar mud might be melted into paving slabs to create roads on the moon, enabling simpler transport throughout its floor.
Miranda Fateri at Aalen College in Germany and her colleagues used a 12-kilowatt laser to warmth a powder made from plagioclase, olivine and pyroxene, developed as an alternative to lunar mud.
At a temperature of 1200°C, the mud compacted and was a black, glassy construction with a compression energy corresponding to that of concrete, which might be usable as a highway floor. “It makes transport on the moon simpler,” says Fateri.
Whereas deploying a laser on the moon to create such a highway may be troublesome, the researchers calculate {that a} 1.5-metre-wide lens might as an alternative be used to focus daylight and produce the identical impact.
Earlier experiments have used lasers to compact reproduction lunar soil, however Fateri says her crew’s 10-centimetre-wide beam is the widest but used.
The researchers then used the laser to create interlocking triangle shapes from the lunar soil, measuring 25 centimetres on either side. They envisage that these shapes might be laid down on the floor of the moon like tiles to create a highway that autos might drive over. This may not solely make driving simpler, however stop lunar mud from being kicked up and damaging tools.
In future, Fateri and her colleagues plan to research whether or not their materials might additionally be used for touchdown or launch pads on the moon. “Should you land on unfastened lunar soil, it creates lots of mud,” says Fateri. “We want touchdown pads.”
