- A 3.5-billion-year-old crater on Mars has been named after Indian geologist M.S. Krishnan.
- The International Astronomical Union (IAU) officially approved the name.
- Five Kerala-based names—Valiamala, Thumba, Bekal, Varkala, and Periyar—are now assigned to nearby craters and a Martian valley.
- The crater is located in Xanthe Terra, a region with evidence of ancient glaciers and rivers.
- Large craters are named after deceased scientists; small craters are named after towns or villages.
- This is the first time Kerala place-names have been used for features on Mars.
