Paris, May 12: European Space Agency (ESA) has developed a drill designed to penetrate 1–2 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 over 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 Finmeccanica in Nerviano, Italy, the drill would first penetrate into the frozen ‘regolith’ and then deliver the samples to a chemical laboratory, which is being developed by the UK’s Open University.
The development team has tested the drill design with simulated lunar soil cooled to –140°C (typical of the expected landing site of Luna-27) but the permanently shadowed regions of the Moon are known to be even colder, at down to –240°C.
