Phobos study sharpens the search for Mars moon origins
Key Takeaways
- Researchers are modeling Phobos’ interior and gravitational field to constrain its origin.
- The giant Stickney Crater may preserve a localized dense region created by the impact that formed it.
- The crater-forming event could date to about 4.2 billion years ago under the giant-impact model or about 2.6 billion years ago under asteroid capture.
- Japan’s MMX mission, due for launch in late 2026, is expected to provide crucial new data on the Martian moon.
