They will then settle down, test some systems. Get some sleep, test some manual controls tomorrow, then do the TLI burn that’ll take it out of earth orbit.

Oh, wow. Just got back online and saw this was stickied. Had I known this thread was going to blow up I would have paid more attention.
My bad.
My bad.

I don’t know when exactly it’s occurring but I do know in the next day or so there is a sequence where they only sleep for 4 hours, wake up to do time critical task, then another 4.
Because of how cramped it is, I don’t think working in shifts is realistic

Just FYI... the lone woman on board is reporting issues with the toilet (yes I know there's not a typical toilet on a space craft)

SpaceX accounts for that as part of the development process. Their willingness to fail is why they've done in 10 years what took NASA 60.
I don’t think the whole “SpaceX vs. NASA” thing is productive or fair, quite honestly.
First off, SpaceX was able to build upon those 60 years of NASA experience.
Second, NASA had already made the decision to shift to industry-led development (rather managing development in-house with cost-plus contracts) before SpaceX ever reached orbit. That was a conscious decision, and it enabled a company like SpaceX to mature and thrive. It’s entirely possible that SpaceX wouldn’t exist today if NASA hadn’t funded Falcon 9 and Dragon development via the COTS program.
None of this is intended to take anything away from SpaceX. They’ve revolutionized space flight. I don’t think there’s any argument about it. I just think it’s crazy how people act like SpaceX bailed NASA out when the opposite is equally true. Ultimately they’ve been partners, and SpaceX’s success should validate NASA’s vision for the future following the end of the Space Shuttle program.
SLS has been a boondoggle, but not so much because of incompetence at NASA. It’s a boondoggle for political reasons. Multiple NASA administrators tried to kill SLS, and one senator from Alabama (Richard Shelby) managed to keep it alive because of the jobs it sustains in his state. I would argue most of the Artemis program’s flaws can be traced back to Richard Shelby’s refusal to let SLS die, in one way or another.

They blast themselves into an orbit around the earth
Then they make some burns to round up that orbit
Then they use a burn to extend that orbit at just the right time to surround the moon
Then later they can do a burn to shrink that orbit to just be around tge moon, or they can let it pull them back toward the Earth.
This guy KSP’s.

Oh there is another cool engineering thing here:
Those engines use hydrogen and oxygen for fuel, which is the ideal in terms of efficiency but brings up a lot of issues that need to be resolved, such has maintaining the cryogenic state of the fuel.
But another one is that it’s TOOOOOO efficient. It generates a lot of superheated gas at high temperatures yes, but it is so high as to surpass our ability to contain it.
The engine bell would completely melt if allowed to.
So what do we do? The engine has two pumps moving oxidizer and fuel into the system. But unlike the oxidizer, it doesn’t pump the hydrogen straight into the chamber.
Instead it gets piped through tubing in the engine bell, both cooling it and expanding it as an evaporated gas. It uses the energy present in that compressed gas to drive a turbine, which is what drives the fuel pumps.
Literally the thermal energy of the engine is what powers the engine.
Sometimes I take for granted I was born and raised in Huntsville, around this type of thing 24/7.. A bunch of my friends are literal rocket scientists, with quite a few working directly on the Artemis program, so I just assume everyone knows this stuff

The good news is I know a few of those. The bad news is......I know a few of those.
I think one of them got lost going to the mailbox a few months back.
ETA: That is not intended as an indictment on his intellect or ability. He's just.......well, odd. Top notch at his job and a math wiz. Yet, he almost lost his driver's license because he couldn't stop running into shite.

"Get some sleep" is probably highly optimistic in this case.
There's no way I could relax with everything going on, with all the implications first of all. Second of all, I'd be in total and complete awe of the view outside the porthole.
Even when traveling in an airplane you feel small and humbled looking down on the landscape, now imagine looking down on a blue and brown/green beach ball. The United States is a few inches wide, Iran is a small speck, all the earths nations and continents interrupting a mostly blue sphere. Every person you've ever known, every person that's ever existed, every bit of human history is contained upon that thing you can now see in totality with your own eyes.
Not only could I not sleep a wink, I'd have the most existential of all existential crises.

From NASA:
quote:
Should the toilet malfunction, the crew will be able to use collapsible contingency urinals, a system that collects urine in a bag and interfaces with the venting system to send the urine overboard. With two different styles designed to accommodate both females and males, the bags hold about a liter of urine each. Should the UWMS fail, the crew will still use the toilet for fecal collection, only without the fan that helps with fecal separation.

Oh, I know exactly what you mean. One of the smartest guys I went to school with, an engineer of course, doesn't have the common sense of a walnut.

I agree 100%. There is room for both and both have their issues.
I was mainly trying to convey that the gotcha "SpaceX is a failure" argument that poster was making was disingenuous and retarded.
You make several great points in your post and NASA (and all of America) should be proud of what was achieved today.

Holy Ears on this dude at the launch presser
He could fly to the moon & not need satellite help for comms reception

Time to break out the 50,000 dollar space poop knife.

I don't know if anyone has posted this yet, but NASA has a live feed from the Orion on youtube:
