Tags: Crater.
Eagle is a 22-metre long impact crater located on the Meridiani Planum extraterrestrial plain situated within the Margaritifer Sinus quadrangle (MC-19) portion of the planet Mars. The Opportunity rover came to rest inside Eagle crater when it landed in 2004. Scientists were delighted that the rover landed there as the crater contains rocky outcroppings that helped prove that Meridiani was once an ocean floor.
