Scientists map lunar regolith thickness across 346 craters
This digest was compiled by AI from multiple sources — links to the originals are below.
Researchers have produced a detailed map of the lunar regolith layer, finding an average thickness of about six meters in ancient highlands and four meters in dark volcanic plains. The map, based on 346 fresh craters and 68 measurement points including Apollo and Chinese mission data, could guide future lunar base sites and resource extraction.
Key Facts
- The average regolith thickness is about six meters in ancient highlands and four meters in dark volcanic plains.
- Researchers studied 346 fresh craters and compared data with measurements at 68 points, including Apollo and Chinese mission data.
- The map may assist in selecting sites for future lunar bases and resource extraction.
Regolith Mapping
Scientists compiled a detailed map of the regolith layer—dust and crushed rock covering the lunar surface. The average thickness is about six meters in ancient highlands and four meters in dark volcanic plains. Researchers examined 346 fresh craters and compared the data with measurements at 68 points, including Apollo and Chinese mission data.
Implications for Exploration
The results confirm that older lunar regions have thicker regolith on average, as they were exposed to meteorite impacts longer. The map could help select locations for future lunar bases and resource extraction. According to scientists, a thin regolith layer is more convenient for construction, while a deeper layer may be of interest for extracting water and other resources.
