China Becomes The First To Land on the Far Side of the Moon and Releases Never-Before-Seen Videos - Siamtoo
When it comes to space exploration, the Chinese space agency has made history and continues to innovate. They have not only become the first country in human history to land a spacecraft on the far side of the moon, but they have also grown the first plants on the moon’s surface, paving the way...

Ah, another leak sprung during refuelling - The idea of being "hardware poor" during testing because the simulations will do the grunt work instead (making it cheaper) is really creating some very unwanted splash-back for NASA right now.
The leak is a Liquid Hydrogen one and they've stopped the fueling process. =To hazard a guess I''d say it's not going today but thats just my guess

SLS = Slightly Leaky Spacecraft
The NASA livestream occassionally shows their CCTV doing close ups of what appears to be external Hydrogen leaks where the supports for the external LOX pipe runs down the outside of the main Hydrogen tank. It's like several leaks (4+ so far I've seen) being shown, not just a single one. Maybe those aren't the "important" leak but it's still a bit shocking to see how many holes there are creating these minor leaks.

I don't get it, why would a spaceship leak? Did they not fill it with water first to make sure?

Use a film set for what?
It's pressure and temp related - Liquid Hydrogen is colder than -252'c and the tank is pressurised to about 3-5 bar - both of those will have an effect on the seals.
This is why NASA "should" (in my obviously expert opinion
) have done lots of destructive hardware testing first despite the cost. Instead they've gone the "cheaper" route and software simulated a lot of the components rather than physically testing a whole bunch of times (due to cost). What they're now finding out is that, with this most recent Scrub effectively being only the 5th time it's been fully fuelled (and its 5th failure), doing more hardware testing (as expensive as it seems) would have been far better than the worldwide embarrassment of NASA rolling out, to great fanfare, something which has shown that NASA seems to be unable to make an existing design work once they'd modified it.

It's also H too ( ), so if there's a way for it to get out it will.
