In search of signs of life on Mars with China's sample return mission Tianwen-3

The article further highlights that the greatest challenge in returning Mars samples to Earth lies not in the formidable technical or scientific obstacles, but in quarantining and monitoring required once these extraterrestrial materials arrive—a process known as planetary protection.As China is poised to become the first country to return potentially biologically active planetary material, including potential life forms, from beyond Earth, the potential risk such substances might pose to terrestrial life, including humans, is a major concern. To address this, China plans to construct a specialized facility on the outskirts of Hefei, its renowned scientific hub, where Martian samples will undergo comprehensive biochemical and pathological testing under strict isolation from Earth's environment.
Only after it is conclusively determined that the samples contain no active biological agents or substances that could threaten Earth's biosphere will they be released to designated laboratories for in-depth scientific analysis.
I think I can read a certain negative #framing here. If it were #NASA, wouldn't we just celebrate the achievement and implicitly assume that NASA will ensure the necessary safety? But when it comes to #China, the mistrust seems to be greater than the appreciation of the technical achievement.

"When a father leads his family with too much force, it's like when a powerful leader controls their country too strictly. Both try to be in charge of everything and make all the rules. Sometimes, people who are harsh at home also want to be strict leaders in bigger ways."

It doesn't have to be this way.
The USA doesn't need to dissolve into callous oligarchy.

I am starting to get a better picture of how this could help others thanks in part to your perspective.
