On 15 October 2026, ESA reported that its Prospect mission will send a drill and science laboratory to the lunar south pole in 2027. The drill will penetrate up to 1 metre into regolith near permanently shadowed craters, where water ice may survive, and will simultaneously scan for ice while extracting a sample. [1]
Prospect will transfer the sample to a miniaturised laboratory and heat it to almost 1,000 °C, testing whether water exists in the region, how it can be used, and where it originated. The mission directly addresses the uncertainty surrounding the availability and physical accessibility of lunar volatiles—critical constraints on sustained habitation and civilisation-scale infrastructure. [1]
The Ark team should track Prospect’s landing site, drilling depth, volatile detection limits, recovered-water yield, energy requirements, and contamination controls. Integrate successful methods into a lunar-resource validation programme, prioritising repeated subsurface sampling, thermal extraction trials, oxygen and hydrogen production, and resource maps that distinguish scientifically detected ice from economically recoverable deposits.
