Gusev crater,Mars. Artwork of the Gusev crater (right of centre),the Apollinaris Patera volcano (upper right) and 'river' Ma'adim Vallis (lower centre).The Sun can be seen upper left. Gusev has a diameter of 90 kilometres and is thought to have been formed three to four billion years ago by an asteroid impact. Scientists believe that water formed a river that drained into the crater. On January 3 2004,NASA's Mars rover 'Spirit' landed in the crater. In March 2004,Spirit found evidence of minerals crystallised out of water,within a rock found in Gusev | |
