From discovering water to snapping selfies: The lasting memories of Mars rover Opportunity

NASA's longest-running rover on Mars, Opportunity, is no more. Officials declared the 15-year-old rover Opportunity dead Wednesday, eight months after by a ferocious dust storm in June. The Mars rover Opportunity is dead after a record-setting 15-year run, but its memory – and scientific discoveries – live on. NASA announced Wednesday that the Mars rover was deemed dead after it hadn't communicated in more than eight months. Opportunity, along with twin Spirit, had unprecedented success and contributed greatly to scientific understand of the red planet, NASA said.
