Summary:
- Researchers have utilized data from the Emirates Mars Mission’s Hope probe to analyze the surface and subsurface composition of Deimos, one of Mars' two moons.
- The study suggests that Deimos is covered by a layer of regolith approximately 120 meters thick, which likely obscures ancient impact craters that would otherwise be visible.
- These findings challenge previous theories regarding the moon's origin, suggesting a more complex geological history than previously assumed, potentially involving a more violent past or a different formation process than simple asteroid capture.
