One thing we can know for certain is that those fish will be swimming sideways and upside down at times. Just like humans, they will have no way to detect what is up and what is down. But they may very well survive the trip.

Your premise is that "The entire world can only bring back 1.7kg with modern-day (2020) technology". Why would you think that is the limit? If you can lift 100,000 kg off the face of the earth (which has much greater gravitational force) and out to the moon, why shouldn't you be able to lift a few tens or even hundreds of kg off the moon (with only 1/6th the gravitational pull) and let it fall back to earth? In fact, thinking about it, that sounds like the easiest part. It's your entire premise that is wrong.

@Javy_Valen_Tain No particularly reason why you should know. Disasters happen all the time, we can't know about all of them.

@WhiteGirlChinaPeanut.online Ok, got it, but the original poster makes this claim: "The only country on earth that was able to bring back a lunar sample was China". That is clearly wrong.

@Singh_King_823 Just to be clear, are you saying that the US didn't bring back any lunar rocks/dust at all? Or what are you trying to say?

@lonesomefencesitter3186 and if the US had also sent up some shovels and a wheel barrow, they could have brought back much more.

@Singh_King_823 As another poster said: The US came and went with a full space craft big enough for three people and more cargo. China came with a small robotic craft, a rover. These two different types of craft can carry very different loads. Like the difference between a rowboat and a container ship.

@Singh_King_823 Chang'e Rover is a very tiny space craft with very limited capacity. The Apollo space craft were significantly bigger, big enough for several people. Basically as big as the SpaceX Dragon Capsule.

@Singh_King_823 But 'the whole world' CAN bring back thousands of kg of material from the moon if we want to. It's just that for the last 40+ years, nobody has had any interest in spending the money to go back to the moon. It's very expensive, there's not much to do up there, and those rocks have no financial value, and very little scientific value. We have had our scientists examining the moon rocks for decades and probably found out everything there is to know about them. Going to the moon is not that hard, but it is extremely expensive. The only reason to go to the moon is for national prestige.

I remember it, though not very clearly. I must have been engaged with other things at the time. It's a bit like a train crash, or a plane crash, just more dramatic.
