> tell me about the marathon crater
I'd be happy to tell you about Marathon Crater. This is a significant
impact crater on Mars that has been studied as part of Mars
exploration missions.
Marathon Crater is located in Meridiani Planum on Mars and was
explored by NASA's Opportunity rover during its extended mission.
The crater is named after Marathon, a town in Texas, following
the naming convention of using Earth locations for features in
Meridiani Planum.... etc etc
