Rover deployed (not real time). Still waiting for actual deployment.

Deploying ramps.

As in discussing.. not actually deploying now..?

Played an animation of the rover deployment. Starts with unlocking of the wheels with some pyros, then solar array wing deployment on the rover, deplyoment of the mast, then the tracks. Rover drives out onto the tracks, and then the tracks are lowered to the surface (two stages...)

Interestingly, the reporter said that it could drive off the tracks, but that it'll be lowered as much as possible - for safety.

I didn't understand ANYthing!
Wasn't it going to land RIGHT NOW at 13:40 UTC???
Why did it already land?!? DID it??? Did it transimt live video? Is a recording available to be viewed again'
What is going to happen now? When is the rover going to be deployed? Will it be a live video?

Mentioned that rover will not talk directly to earth until it is out of communication shadow of the lander.

CCTV - Says 27 minutes post landing.

Discussing technical aspects of Landing and applicability to landing robots on other bodies, including Mars.

yes, it landed. Speculation is that it might land an orbit later. It didn't transmit live video; it did transmit live frames and telemetry. A recording will be sent to the earth later, hopefully.
The rover will perform system checks for quite a few hours now. After that, the rover will be deployed.

Calm down.

Yeah, I wonder why they didn't orient the lander such that the deployment was towards the Earth?

Are we expecting any more major events before CCTV coverage ends in 15 mins?

Seems to be oriented to maximize solar panels for the long term.

Working sequence after landed


my rough translate...

solar array deploy
Gyro shut down
Accelerometer shut down
lander charging for rover
Directional antenna unlock
Rover's wheel unlock
ramp unlock (second times)
Propellant passivation
Directional antenna start to transmit data
Surveillance camera test taking photo


so we may expect can see some photo from lunar surface

CCTV - Discussing:

Lunar rover's radar's two frequencies for shallow and deeper viewing into the Moon's surface.

Heating via radioactive units.

Already have 59 pictures from landing sent back. Geologist discussing flat landing area.
