Kind: research · Impact: low

## In brief

- Lunar impact craters are widely used to determine the ages of surface units.
- Craters can also act as cold traps that preserve water ice.
- Craters degrade over time, which affects both of these uses.

## Why it matters

Crater degradation can bias the age estimates and the water-ice preservation that planetary scientists rely on craters to infer.
