Microwave heating of lunar regolith advances Moon construction

A joint Spanish-British research team has demonstrated that lunar regolith can be heated more efficiently with microwaves than with traditional ovens, paving the way for building roads, runways, and other structures on the Moon using local materials. Source: ABC.es Source: Infobae

How it works

The team, from the Universitat Politècnica de València (UPV) and the Surrey Space Centre, studied two types of lunar regolith simulants: those from the lunar seas and highlands. They measured dielectric properties to see how much energy the materials store and lose when heated. By heating under nitrogen to avoid Earth atmosphere contamination, they found that microwaves allow the regolith to absorb energy faster than conventional heating.

Significance

This method is more energy-efficient and faster, making in-situ construction more sustainable. According to researcher Beatriz García-Baños, 'Understanding how lunar regolith responds to microwave heating is key to designing more efficient processes for construction on the Moon.'
