The Moon’s Dark Shadows To Be Explored By This Laser-Powered Rover

The Moon‘s poles are believed to be Irish in water ice and more valuable materials and one of the quests that experts are planning involves the exploration of the permanently-shadowed craters around the poles.

SciTechDaily revealed that ESA’s Discovery & Preparation program funded the design of a laser system that could keep a river supplied with power from up to 15 km away while it explores the dark craters that we mentioned above.

It’s important to note the fact that at high latitudes, the Sun stays low on the horizon all year round and it’s casting shadows that are keeping the sunken craters flooded in permanent shadows and the potential timescale for this is billions of years, according to the same online publication that we mentioned above.

According to the latest data, these “permanently shadowed regions” are rich in hydrogen, and this is something that suggests the fact that water ice can be found there.

Such ice has scientific value and it would also be really precious for lunar colonists as well because it could be a source of drinking water, oxygen for breathing, and a source of hydrogen rocket fuel.

In order to know some things for sure, drilling these craters is required.

Any rover that would have to do this will also have to get on without solar polar and to resist at temperatures of about -240 degrees Celsius.

Analyzing a laser-based power system 

“The standard suggestion for such a situation is to fit the rover with nuclear-based radioisotope thermoelectric generators,” according to ESA robotics engineer Michel Van Winnendael.

He continued and explained, “But this presents problems of complexity, cost, and thermal management – the rover could warm up so much that prospecting and analyzing ice samples actually becomes impractical.”

As an alternative, the study analyzed harnessing a laser-based power system that’s similar to the laser experiments here that are keeping drones powered and flying for hours.

SciTechDaily notes that the 10-month PHILIP, “Powering rovers by High-Intensity Laser Induction on Planets,” contract was undertaken for ESA by Italy’s Leonardo company and Romania’s National Institute of Research and Development for Optoelectronics. Now, there’s a complete laser-powered exploration mission design.
