Good luck to China, but I hope they're more open than they were with the Moon missions. Those missions were an example of how to be incredibly secretive despite being a science mission. Release the data live, don't filter it through several government agencies (and don't make false absurd claims like finding gelatin/jelly on the moon).

That`s their style and I don`t think it would change any time soon. Just adapt to it. Also, they were saying "gelatin/jelly-like soil on the moon" not straight "gelatin/jelly"

Looks like despite the failure of 2011 mission and rejection/cancellation of the 2015 mission, China did kept to the initial 2003 prediction of launching a rover in 2020. The second article on Beidou-1 gyroscopes just shows how far China has come along since then. Let's see how it will turn out as it rolled first two steps together in the usual three step strategy.

A very nice launch, congratulations!
I only wish their government had enough faith in their engineers to live-stream the fruits of their labor.

"Good luck to China, but I hope they're more open than they were with the Moon missions."
Curious. I had been saying the opposite elsewhere. I am impressed with the openness of China, with announcements and a few images every lunar day, as well as a drive diary with interesting additional details every month, and full data release after a year. I think that's as much as we non-Chinese taxpayers have any right to expect, and I contrast it with, for instance, Chandrayaan 2. Remember Chandrayaan 2? We get a data release in the fall, but nothing at all on a regular basis. And will Russia be any better with Luna 25? And it really remains to be seen how private entities will behave as CLPS and other programs proceed at the Moon. Some might be open, others highly secretive. We are spoiled by NASA but China is doing OK.

Sure, a lot of the bloom went off the Chandrayaan2 mission because of the landing failure, and that may have resulted in the information outflow becoming more reserved. Perhaps the information flow may pick up again, if a Chandrayaan3 succeeds. I hope that Tianwen-1's very ambitious mission fully meets all its objectives, so that similar curtailment of information isn't seen there. It seems to speak to the confidence of the mission planners, that they're aiming for so many incredible feats on their first Mars outing. If successful, China will have achieved a major leap forward in its Mars capabilities, and nearly closed the gap with the US in one fell swoop. Is there going to be any live telecast of the landing?

That's nothing that I remember. I remember them putting out a press release every few weeks with scant details and a single image. No images every day and no drive log.

You have missed them. They are out there. I usually post on this topic in Unmannedspaceflight rather than here.

also, while it's true that NASA Mars rovers release their images in real time (and in jpg format, I would hardly call them "data"), other missions don't. see for ex. OSIRIS-REx

Well in that case it is not surprising that the OP drew that conclusion being as that is hardly a mainstream site even amongst spaceflight followers. Nor to my mind is it that user friendly being as it doesn’t even reformat for mobile devices, something most sites manage these days.

As a person who actually worked with Osiris-Rex data as part of the Cosmoquest Mapping Project, I tend to disagree slightly. When the citizen science initiative was opened, there was a whole lot of imaging data. You only had to register. I personally mapped more than 250 photos
But if you mean photos that get published on the web as soon as they're taken, then yes. Most orbiters don't publish their photos in real time anyway. Surface missions, that's another cup of beer

3 screens from an image i saw on weibo.
1st is Spacecraft's separation point parameters
The best I can make out, these should be the values and h/t to penguin for row name translations
1) Time(s) 2169.956 -8.002 2177.958
2) Longitude -126.493 -0.906 -125.587
3) Latitude -29.617 -0.009 -29.608
4) Altitude(km) 478.986 -21.212 500.198
5) Absolute Velocity (m/s) 11327.320 15.926 11311.394
6) Absolute Velocity Inclination() 12.044 -0.414 12.458

I know Utopia Planitia is a very big place, but I can't resist asking - do we have any clue how far will Tianwen land (or crash) from the long dead Viking 2 ?

Yes. About 1000 km south near latitude 25 degrees.

http://moon.bao.ac.cn/All the photos and data from CLEP program can be found here.
I guess all you have to do is learn Chinese better. But most people won`t.
Their (CNSA) main focus is 1.4billion Chinese people who is speaking Chinese mostly. Don`t expect they doing same thing as NASA posting on mostly-English-users-twitter like "whoa our new probe data&photo could be found here, take a look."
No, that`s never gonna happen.
Even tianwen-1 no official live stream is getting a huge amount of complaint in Chinese space fans, they seem not to care about that much. There should be another huge probe CE5 in November, I doubt no live stream for that as well. But who knows...

This is fantastic, thanks!
(Too bad they don't include azimuth - one number short of a full state vector...)
