Huh. For a lot of rocket hardware, the isogrid gets machined flat and then gently bent into a cylindrical section. Interesting that they're machining it curved.

NASA's tweet with the same news:

Quote from: NASA Artemis
We’ve selected @SpaceX to provide launch services for the Power and Propulsion Element (PPE) and Habitation and Logistics Outpost (HALO)—the foundational elements of the #Artemis Gateway.

See below:

There are fairly recent (within the last six months) FISO presentations from Scott Tilley (Maxar) and Chad Davis (Northop Grumman) on the co-manifested PPE/HALO:

http://fiso.spiritastro.net/telecon/Tilley_9-30-20/

http://fiso.spiritastro.net/telecon/Davis_11-4-20/

They mention a sub-GTO insertion and ~300 days for orbit raising.

There was a pretty energetic and interesting thread about this decision in the SpaceX Missions sub forum and then one day last week I tried to click on it and it had gone *poof.* Why was it deleted? Maybe a Mod can explain please?

The first Node STA for Space Station Freedom (*before* production for nodes was switched to Alenia) tried the forming method you refer to. Unfortunately, the alloy used was too resilient and after the presses were removed, the structure “rebounded” and hadn’t been bent to the proper chord section. There were manufacturing experiments to determine how much panels must be over-bent to get the right residual curve and chord length but all that was out of my area so I only paid it passing attention at the time. Presumably after building so many ISS structures, Alenia knows the preferred method to use for this kind of module.

That's the thread I was talking about - hell, I *posted* in that thread but then it seemed to just disappear for me. When I last tried to click on it a few days ago, I got a forum error page that said something like, "You don't have permission to view this page" or something like that, and when I refreshed my screen, the thread was completely gone. Now that I have completely cleared my browser cache and tried again, I see it.

So; after the co-launch of the first two modules, if the first Habitation module is then attached, does this represent the first, basic usable configuration of the Gateway?

AFAIK the PPE / HALO are usable on their own.

Lueders says she's disappointed Russia hasn't joined Gateway.  Have learned a lot from them in ISS, they have diff approach.  Hope we can find ways to work together in future.

She [Lueders] adds she is “disappointed” that Russia doesn’t plan to cooperate on the lunar Gateway because they have different priorities. Hopes to find future partnerships with them.

See below:

Quote from: Joey Roulette
After Russia and China announced their agreement to work on a lunar space station, NASA now says in response to @verge questions for comment that it's "pursuing other options for the provider of" the Lunar Gateway's airlock, which it had long planned to get from Russia.

Could you imagine Russia, China and NASA trying to compete to build orbital station aroun2026-2028 and the same time Space monthly land on moon just as test for Mars excursion.
