One thing they seems to have got working fairly reliably is the lunar landing of the probe using image processing to guide the final approach and touch down. It seems to have worked well in this and the previous mission, there are videos on youtube of that.

The other component is the autonomous docking of the return probe in lunar orbit.

Soviets have done a lunar sample return, but they had a probe that would lift off directly into a earth return trajectory, but that seems to have limited both the liftoff mass and the possible zones in moon from which it can lift off. This seems a much more complex mission than that.

Also some animated videos of the misson show a skip re-entry back to earth, don't know if it is the case during this particular flight.

These are the first time rock samples from the far side of the moon has been retrieved.

This was a fairly complex mission with autonomous docking of the sample capsule in lunar orbit and a skip re-entry back into earth.

Essentially a smaller scale Appolo mission but done with robots.

But the First Ammendment really does say "Congress shall make no law .." without any caveats for national security or even war-time exemptions.

Yes, but you think that possibility of government oversight/monitoring is an inherent necessity for government permitting any kind of media to operate in the US?

If doesn't work in many cases anyway, Government has no way to track who is tuning in and listening to hostile radio broadcasts.

Even it might be hostile propaganda, First ammendment protects both publishing and consuming content, without any "national security" considerations. But US lawmakers are now seemingly keen to introduce such conditions in the publishing and consuming of content.

During the cold war it was perfectly legal for the Soviet Life magazine to be published in the US and for people to buy and read it.

First ammendment really does say that "Congress shall make no law .." without any caveats for national security or even war-time exemptions.

It will be interesting to see how it plays out in the SCOTUS.

Any idea of high res images from Tianwen-1, as per reports they have imaged most of Mars surface, and being a more recent mission, may have better camera.

Cisco and Huawei can be subject to same set of regulations aginst having backdoors etc. But instead of general regulations and measures, what is promulgated is merely action against 2 particular firms, that is a targeted/particular regulation.

Weather such targetted/discriminatory regulation as opposed to universal regulation is a legal action is a valid question.

This particular law seems to give grant too much discretionary powers to the Executive, which never is a good idea.
