Structural asymmetry in martian impact craters as an indicator for an impact trajectory

► We analyzed structural uplifts of several oblique impact craters on Mars. ► A new tool is provided to determine the impact trajectory in complex impact craters. ► The strike of bedrock is predominantly perpendicular to the impact trajectory. ► The majority of faults trend parallel to the impact trajectory. ► Terrestrial craters with these features are interpreted as oblique impacts.
