China set to launch an ambitious lander mission to Mars

On Sunday, an orbiter built by the United Arab Emirates launched to Mars. Next week, possibly as early as Thursday, July 30, NASA will launch is large, 1.05-ton Perseverance rover toward the red planet.

Sandwiched in between these to missions, however, is China's first interplanetary spacecraft. With its ambitious Tianwen 1 mission, China will attempt to orbit and land on Mars on its first attempt, subsequently deploying a rover. This is significant, because the typical mode of exploration is to first flyby a new world, then enter orbit, and only then send a spacecraft to land and potentially rove around.

China has the benefit of learning from NASA's exploration of the red planet, of course. Even before Perseverance, NASA has landed eight spacecraft successfully on the surface of Mars over a period of decades.
