A drill designed to penetrate 1 to 2 m into the lunar surface is envisaged by ESA to fly to the Moon’s south pole on Russia’s Luna-27 lander in 2020.

“It is an essential part of a science and exploration package being developed to reach, extract and analyse samples from beneath the surface in the Moon’s south polar region,” explains lunar exploration systems engineer Richard Fisackerly.

“This region is of great interest to lunar researchers and explorers because the low angle of the Sun on the horizon leads to areas of partial or even complete shadow. These shadowed areas and permanently dark crater floors, where sunlight never reaches, are believed to hide water ice and other frozen volatiles.”

Developed by Finemeccania in Nerviano, Italy, the drill would first penetrate into the frozen regolith and then deliver the samples to a chemical laboratory, its development led by the Open University in the UK.

The loud noise heard during this test is not the drill itself but a feed of liquid nitrogen used to maintain the temperature of the lunar soil simulant being drilled down through at -140C. This cold temperature is typical of the expected landing site of Luna-27, however the permanently shadowed areas of the Moon are known to be even colder, down to -240C.

The drill system plus laboratory are collectively known as Prospect:  Platform for Resource Observation and in-Situ Prospecting in support of Exploration, Commercial exploitation & Transportation.
