NASA's Perseverance rover launched on a journey to Mars Thursday to hunt for signs of past alien life on the Red Planet.

Why it matters: The rover is the third spacecraft lofted to Mars this month, with the first two sent by the United Arab Emirates and China.

The Florida Division of Emergency Management announced Wednesday all state-supported coronavirus testing sites will temporarily close this week ahead of the anticipated arrival of a weather system that's expected to become a tropical storm.

Why it matters: Florida has reported more than 450,00 cases and over 6,300 deaths from COVID-19, including a record 216 deaths in 24 hours announced Wednesday. "All sites have free standing structures including tents and other equipment, which cannot withstand tropical storm force winds, and could cause damage to people and property if not secured," the emergency management's statement said.
