Opportunity, NASA’s longest-running Mars rover, has finally been declared dead after it went dark eight months ago following a dust storm, the Associated Press reports.

The big picture: Opportunity landed on Mars in January 2004 and was originally intended to operate for just 90 days. Over the course of its 15-year lifespan, in which it covered a record 28 miles, Opportunity found evidence that ancient Mars had water and was likely capable of sustaining life.

This year’s Super Bowl will be held in the most environmentally acclaimed sports stadium in the U.S., the Mercedes-Benz Stadium in Atlanta. The 2-million-square-foot arena, designed by HOK, opened to the public in August 2017 and was the first professional sports stadium in the U.S. to achieve Platinum LEED certification, the highest rating from the U.S. Green Building Council.

Why it matters: A typical NFL game may produce up to 35 tons of waste, or roughly 1.5 pounds per guest. Showcasing sustainability efforts at these highly watched and attended events will help educate fans, reduce operating costs for owners and ultimately lessen the environmental impact for surrounding neighborhoods.
