China's Tianwen-1 mission will enter Mars orbit

The red planet's second visitor this year will be Tianwen-1, which aims to be China's first successful journey to another planet. After its arrival, the robotic orbiter will conduct a series of preparations, and then attempt to land a rover on Mars in May. NASA is the only space program so far to get a hang of difficult Martian surface landings, and a successful touchdown would be further evidence of China's engineering progress.
