The nation's orbiter arrived in Mars orbit months ago, and it's now ready to send its rover down to the surface.

RUNDOWN SHOWS:
1. Show Tianwen-1 orbiter arriving in Mars orbit.
2. Show lander unit detaching from orbiter, start sequence lander unit heating in reentry
3. Continue reentry flames sequence, show parachute deploying, heat shield falling away
4. Landing cradle's legs deploy, parachute detaches, lander falls free
5. As lander falls, main rocket fires, then side rockets join, start ramp deployment sequence
6. Finish ramp deployment sequence, rover unfolds, drives off lander via ramp


VOICEOVER (in English):
The Chinese National Space Administration, or CNSA, says its Tianwen-1 orbiter will release its Zhurong Mars rover on 17 May.

The orbiter arrived in Mars orbit on 24 February, carrying with it the rover and its landing cradle.

The lander will detach from the orbiter and start to descend into Mars' thin atmosphere, protected by a heat shield that's designed to also slow the lander down with its sheer bluntness.

Once the lander slows down enough, a large parachute will open and the heat shield will fall away, exposing the landing cradle.

The cradle's landing legs would then deploy and the parachute would detach to let the lander fall freely.

The CNSA says the lander would then fire a number of rockets to slow its descent, while also keeping the lander in an upright position until it touches down.

After touchdown, the lander would deploy a ramp while the rover deploys its sensor arms and solar panels.

If the mission is successful, China would become the first country to land a rover on Mars on its first attempt.
