This precious resource has been accumulating for billions of years on the permanently shadowed floors of craters in the region, scientists say.AdvertisementAdvertisementNASA didn’t go into the moon base-planning process with a big footprint as a priority. Rather, it emerged naturally, as all of the envisioned elements started coming together in planners’ heads.”There’s no one spot that covers all the science, all the technology, all the habitation needs of the surface, and even within the local area, you have to consider the terrain,” NASA’s Nujoud Merancy, chief architect of the Moon Base program, said during today’s briefing.Artist’s impression of a NASA MoonFall drone helping to mark the perimeter of the agency’s planned lunar base. | Credit: NASA”So, you’ll have the habitats on the tops of the hills where they get sunlight,” she added. “Power systems — nuclear systems — need to be a kilometer or more away for the radiation protection, so all of these things, when you start putting them together, end up sprawling a little bit more like a city as you start building it out.”And scientists and mission planners still don’t know a lot about the lunar south pole, which is another reason for a settlement there to cover a lot of ground, according to García-Galán.AdvertisementAdvert …
