Any idea, when the first image will be released?

Any idea, when the first image will be released?

CNSA vice-chief Wu Yanhua reports on the following future plans:

May 17 - fourth braking to enter relay orbit
May 22 - rover rolls off lander deck
May 27 - Lander/rover mutual photographing session (so lander has deck cameras too)
May 28 - 1st scientific data downlink

Wow ... only so late?

Wow ... only so late?

because the orbiter needs a week to fly over again. NASA on the other hand already has many relay satellites which is why we quickly see photos from it

Tianwen1 is the only relay satellite for China. We will have to wait for the satellite to fly over the landing site.

Than ks a lot for this explanation!

Orbiter is on an elliptical orbit right? Shouldn't China circularize it?

NASA has access to Mars Reconnaissance Orbiter, Mars Odyssey and Mars Express for relay. CNSA doesn't.

Are they going to send more relay satellites?

Something shown on CNSA TV interview screen, some schemed milestone operation yesterday:

05-15 08:01:24 Rover position stabilized.
05-15 08:14:39 Rover communication with earth started.
05-15 08:32:04 Rover communication with earth ended.
05-15 08:38:04 Rover unlocked from the lander platform and raised.
05-15 08:59:04 Rover solar panel unfolded.
05-15 09:48:39 Orbiter orbit and posture to the sun adjustment started.
05-15 12:00:39 Fixed-link remote sensor data downlink established and download started.
05-15 12:29:39 Short range remote sensor data downlink established and download started.
05-15 13:15:39 Orbit changing & orbiter / lander separation record data download started.


It seems the rover is still waiting for her battery to be fully charged, but the lander has established datalink with the orbiter and started to send back data.

Maybe we can see the first local picture soon.

I think the orbiter cycle won't be one week long or more.
But the data download operation need to wait for the China local station, which has the large aperture antena, to be pointing to mars.
