Well, typically partnering means bringing in other companies that specialize in the secondary aspects of a complex project. It is surprising that their launch provider has only ever built a carnival ride so far.

Not to mention they are the partner for human rating, and they have literally never sent a human into space, and when they do it will literally be for an amount of time the passengers could plausibly hold their breath.

True, but a month or two ago I would have thought SpaceX certainly had the lead in man rating.  I suspect ULA holds the lead for American human [orbital] ratings right now.

You mean Boeing, right?

Don't think the ULA is interested in man-rating any of their rockets.

Okay going to do an image dump, sorry in advance. Jeff Faust's twitter is a gold mine.

Comparison of Lunar Capabilities in 2024 vs. those that will be available by 2028
Basically an explanation for why we'll be able to stay longer on the later missions. We really, really, need to get the Z2 to a working state, especially since I believe it has been designed primarily with EVA expeditions in mind until recently, not Lunar surface missions.

Possible Landing Sites / Future Surface Outpost Location
No peaks of eternal sunlight, but something close. Also with good access to Lunar ice for possible future ISRU.

Why NRHO was selected for the Gateway
Kinda weird they show the BFR and NA when they're talking about a 15 mt to TLI capacity. That's for existing commercial launchers; those two would be roughly on par with the SLS. Possibly surpassing it, depending on whether Block 1B becomes a thing

NG was just selected (no competition) for the Gateway Hab module, to be based on their Antares ISS resupply spacecraft.

No cost released.

Cygnus, actually. Antares is the rocket.

It's called the Minimal Habitation Module, which I believe is simply the new name for the US utilization module. It's essentially an over-glorified docking node with life support capability.

Sole-sourcing the module was justified by NASA on the basis of schedule (NASA said bidding it out would add 12-18 months of delay). NGIS got the win because they had already done a lot of work on this concept, and had drawn-up detailed plans on how they could build it with existing parts and tooling.

I’ve never heard that saying before but somehow I know exactly what it means XD

(btw, I was thinking about this stuff recently and came to the idea of what would happen if there was a new space rush involving China. 

Pretty sure the US government would go bankrupt trying to keep pace alone this time... say what you will about China, they have political endurance (and deep pockets) the US government can only dream of, so partnering with commercial companies is probably a survival strategy as much as... well, pork spreading XD.)

All the other space programs combined have a lower budget than NASA.

China's real space budget is assumed to be much higher than the officially reported numbers.

Yeah, and/or mixed with military expense (of course the same is true of US space expense, gotta add a few billion for the Pentagon, at least). I saw another graph that somehow corrected for the cost of things, and what value they got in constant dollars, and it put the US at closer to 40 B$, but the PRC at more like 11 B$ (so 25% vs 10%).

@tater 

China is in a much better financial position than the US, I’m speaking in terms of that, not what is currently supplied for their current programs comparatively.

I mean there’s heaps of evidence so you can’t say by any stretch that “it’s simply put, untrue” there’s nothing simple about it.
