Columbus is a crater in the Terra Sirenum of Mars. It is 119 km in diameter and was named after Christopher Columbus, Italian explorer (1451–1506). The discovery of sulfates and clay minerals in sediments within Columbus crater are strong evidence that a lake once existed in the crater. Research with an orbiting near-infrared spectrometer, which reveals the types of minerals present based on the wavelengths of light they absorb, found evidence of layers of both clay and sulfates in Columbus crater. This is exactly what would appear if a large lake had slowly evaporated. Moreover, because some layers contained gypsum, a sulfate which forms in relatively fresh water, life could have formed in the crater.

| - Columbus és el nom d'un colossal cràter d'impacte al planeta Mart situat a 29° 17′ S, 194° 01′ E. L'impacte per un asteroide va causar un obertura de 119 quilòmetres de diàmetre a la superfície del planeta, un dels cràters de Mart més notoris i millor conservats, situat en el quadrant Memnonia. El nom del cràter va ser aprovat el 1976 per la Unió Astronòmica Internacional en honor de l'explorador genovés Cristòfor Colom (1451-1506). El cràter Columbus es caracteritza per tenir capes o estrats, alguns dels quals solen associar-se a minerals hidratats, com el sofre. (ca)
