Lunar exploration timeline.

They forgot about SELENE (Kaguya)

Professor Yuagong answers a final question about the future of lunar exploration with an expanding number of national players (no mention of commercial exploration/exploitation?), and the possibility of lunar international law to regulate disputes, and the establishment of a "lunar village."

Normally I just follow along with the threads here on NSF, but I had to see if anyone else noticed that according CGTN, the SpaceX Starship apperently contributed to this landing? Lol

Their timeline apparently focuses on "firsts"--Hiten was the first Japanese lunar orbiter.
(Plus all Chinese lunar missions)

Some background on the target region, one of the most interesting scientific AND resource-utilization regions on the moon, as US scientists realized years ago ==

A South Pole-Aitken Basin sample return mission was prioritized in the (American) 2001 planetary science decadal survey, and recognized as scientifically important long before then.

Chang’e-4 lands on the Moon and sends back first images

The lack of coverage - especially on CGTN - is not just frustrating it is bizzare!

Their program, their coverage.

Live with it.

Most of the people who demand live coverage of space events are living in Europe and the USA, and our culture focuses too much on instant gratification. People complained on Twitter that New Horizons photos aren't published instantly when they are received on Earth. Even a few hours delay (until the press conference) was enough to annoy certain enthusiasts.

The Chinese understand things differently

I remember the 2010: Second Odyssey by Arthur Clarke and Tsien spacecraft. Some spoilers : the Chinese never announced what was the purpose of Tsien, and it secretly leaved Low earth orbit to head for Europa. And yes - it was their spacecraft, their right how to operate it and how public it would be.

Actually, there's one thing we can do. If we are unhappy with how other countries operate their missions... then we can ask our governments and countries to make their own missions. Certainly NASA or ESA can do it, right? New Horizons wouldn't have happened without public support. We can do it again.

If you have a point to make - I'm not sure what that is... Why pick on me?! Your irritation mystifies me... (a little)

EDIT: Clarification of my remarks - The Chang'e 3 landing a few years ago was carried absolutely live in great detail. This mission was not - that's what was bizzare to me! They can certainly do what they like - they don't care what a foreigner like me thinks. But your attempted suppression of my opinion is something I would never do to you.

Short report by CCTV13. The lack of a live broadcast is I think a reflection of what Blackstar pointed out a while ago, that China is becoming more restrictive. The risky Chang'e 3 landing was shown live five years ago and it was great to participate in that moment.

Let's not forget that a Chinese rocket (Long March 5) suffered a launch failure 1.5 years ago, and it was broadcast live. This certainly had an impact. The landing of Chang'e 4 was very risky - it truly went where nobody has gone before. Perhaps the Chinese didn't want to risk another failure being broadcast live.

cjx007 · « **Reply #156 on:** 01/03/2019 07:56 am »

Another rumor says (yup, there're always romors for everything), the lack of coverage is due to they don't want to draw too much attentions under current interesting trade war.

Is this the first time that China achieves an... absolute "first time" or there have been others in the past, AFAYK?

EDIT: actually two, considering the dual communication system as a separate one and earlier...

Congratulations China, what a great start into 2019. Please continue and fingers crossed for Boots on the Moon in 2030. Hope there is going to be a race though

An excellent question. I may be wrong, but I think the Chinese achieved another first in the past - moon orbiting + asteroid flyby (Chang'e 2 mission). A similar dual mission of the USA (Clementine) was not successful - the spacecraft orbited the moon, but failed to make a scientific flyby of an asteroid.
