Tianwen 1 successfully entered the orbit around Mars on 10 February.
A 3000N engine was ignited at 19:52 BJT to decelerate Tianwen 1, according to the China National Space Administration (CNSA). After about 15 minutes, the spacecraft, including an orbiter, a lander and a rover, had slowed enough to be captured by Mars' gravity and entered an elliptical orbit around the Red Planet, with its closest distance from the Martian surface at about 400 km. It will take Tianwen 1 about 10 Earth days to complete one circle. Tianwen 1 will now conduct multiple orbital corrections to enter a temporary Mars parking orbit, surveying potential landing sites in preparation to land in May or June.
