USA Artemis II - 10-day crewed mission

So I looked it up and if my numbers are accurate then Artemis II will not go further from Earth than any human has ever gone before. Someone correct me if I'm wrong, but the numbers I found said that the Moon was 404,418 km from Earth at the time of the Apollo 13 mission (which is what everything I've read uses for the comparison) and the Moon right now is 389,875 km from Earth (the normal variation in distance is 356,400 km - 406,700 km), for a difference of 14,543 km (or 8,725.8 miles). Artemis II would have to go about 9,000 miles above the Moon to set a new record and as far as I know the mission plan is for considerably less than that.

Plus I keep hearing people talk about what they'll see on Farside, when in reality Farside will be almost entirely in the dark during the mission. The Moon has a two week day and a two week night, and with the Moon at its full phase (for Earth) that puts Farside smack in the middle of its night cycle (with a sliver of daylight on Farside by the time the mission gets there in a few days).

But it could be an interesting part of the mission to use SAR or other fun toys to see what the chinese are supposedly doing on the farside.

I wonder if a good LEP (Laser Excited Phosphor) pointed back to Earth would be seen from that distance? ... Or human to human Amateur radio contacts from that distance...

BREAKING: The toilet on NASA’s latest Artemis Moon mission spacecraft is malfunctioning.

Sassington MC:

Speaking of the Artemis II toilet, National Geographic and Christina Koch actually gave a tour of what it looks like

Space toilets are notorious for being annoying.

"As bandwidth allows, this stream will feature live views from Artemis II's Orion spacecraft, without commentary, as it makes its journey around the Moon. This stream will begin as Artemis II begins its ascent into space and will conclude shortly before Orion splashes down into the Pacific Ocean. Viewers will see a blue screen if there is a loss of signal, or if the bandwidth is needed for mission activities. Viewers may see what appears to be a black screen when the vehicle is in darkness."

I would think it’s kind of their job to suck a$$ given the situation.. The toilets not the plumbers..

Consider the airflow needed to capture liquids without gravity, odors, solids, etc.

Things they never addressed in Star Wars.

10.days is just a snapshot.

Water and waste can be stored.

Long term space travel presents a whole nother set of problems.

It's all gotta be recycled.

I'm thinking they would see considerably less of Farside in darkness than they would of Earth in darkness lit by a full Moon (and removing all the lights). Their spacesuits are theoretically good for open space, and I assume they'd have to go outside to point something at the surface unless they have something hidden behind panels on the outside of the Orion crew capsule. Interestingly enough, the Chinese should be able to track the Orion on Farside better than the U.S., since last I heard the Chinese have something at the far Lagrange point for full-time communications with their stuff on Farside.

And speaking of the Chinese, they just launched their replacement of their cargo spacecraft on a test flight. Either the Chinese taikonauts don't eat a lot or the Tianzhou cargo spacecraft is huge, since they only have a single Tianzhou flight planned in 2026 to resupply Tiangong. Compare that to Russia launching a Progress every three months or so and a steady supply of third party cargo spacecraft going to ISS.

So far, so good. They made it off the pad and are in earth orbit getting ready to slingshot around to the moon.

I really hope they make it there and back safely, but I just have this feeling of dread. I seriously doubt NASA is capable of actually getting the job done correctly. DEI is the enemy and they have plenty of that.

Well, according to AI (which is NEVER wrong, LOL!), Artemis 2 will break Apollo 13's record by roughly 4000 miles. I asked it, "will Artemis 2 be the farthest human have ever traveled from earth?", and below is its answer.
