China launches ambitious attempt to land rover on Mars

Tianwen-1 was launched on a Long March-5 carrier rocket from Hainan Island, a resort province off the south coast of the mainland, state media said. It marked the second flight to Mars this week, after a United Arab Emirates orbiter blasted off on a rocket from Japan on Monday. And the U.S. is aiming to launch Perseverance, its most sophisticated Mars rover ever, from Cape Canaveral, Florida, next week.
