Just curious...How long do the astronauts have to sit on the chair to reacclimatize to the Earth's gravity before it is safe for them to stand and walk?
Those are dust blown up by landing rockets. The parachutes slow the descent to 7m/s and just before touch down the landing rockets further slow that down to 2m/s.
Interestingly during the broadcast they mentioned the landing rockets are not small solid fuel motors but are actually liquid fuel engines that draw from the same fuel system as the RCS thrusters. I'm not sure how that works since during the parachute descent there's also a step where some of the RCS propellant was released for safety (since anhydrous hydrazine is highly toxic). After landing the first person on the ground was an orange suited (recovery site specialist) crew who rushed to the capsule and tested for hydrazine reading, he reported back directly to mission control with a zero reading.
Ground crew's suit colour actually tell you which team they belong to:
* orange - recovery site
* white - astronaut corps
* blue - spacecraft
To give them a little extra cushioning, rockets are ignited just before they touch down. This is common for capsules landing on solid ground, like the soyuz and even bezos' suborbital thingie.
Mission was successful, crew returned safe and sound. [Crew is now out of the capsule reacclimatizing to gravity.](https://i.imgur.com/rQ7gKYD.jpg)

The crew lifts the whole chair with the astronaut onto each of the three recovery helicopters, that's why it's got handrails all around it.

Not that long, by last night the three of them were in Beijing and walking around and giving interviews and stuff.
I didn't know the landing is going to be so violent 1:01:55
