"China's first Mars probe Tianwen-1 has successfully entered the orbit of the red planet after a crucial "brake" to decelerate and be captured by Mars gravity," according to China National Space Administration (CNSA).

CNSA told state-run Global Times after a 15-minute firing of its 3,000-newton engines, Tianwen-1 "reached an elliptical Mars orbit at around 400 kilometers from the planet." 

After surveying the planet, Tianwen-1 will select a landing spot and touch down between May and June.

Here's the timeline of the Mars research mission.
