Which crater is the landing site of NASA's Opportunity rover?

The crater that served as NASA’s Opportunity rover landing site was Eagle crater.

Opportunity landed inside the small Eagle crater on Meridiani Planum in January 2004. The rover arrived enclosed in airbags and came to rest in a dramatic “hole-in-one” landing, surrounded by exposed layered rocks. The crater is roughly a few tens of metres across, making it tiny compared with many major Martian impact basins.

Those nearby outcrops quickly became scientifically important. Opportunity found sedimentary rocks, sulfate minerals, and hematite-rich spherules nicknamed “blueberries,” evidence that liquid water had once altered the region. The observations helped show that Meridiani Planum had an ancient, acidic and salty watery environment.

A common mix-up is Endeavour crater: Opportunity eventually drove to and explored its rim, but it did not land there. Gusev crater was the destination of Spirit, while Gale crater became Curiosity’s landing site. Opportunity later traveled far beyond Eagle before its mission ended in 2019.
