Wow, what a frankenrocket.

Well yes. But no more a frankenrocket than SLS, if you think about it.

You'd have to shrink the drop tanks to about 33% of their normal length. But it would send 34 tonnes to TLI with a GLOW of just 2,006 tonnes, significantly smaller than SLS Block 1.

Were the Pyrios booster and F-1B scrapped, or are they still planning to do that, by, like, 2050?

Scrapped. They want to go with bigger, more dangerous, more aggressive solid boosters that weigh less and pack more propellant.

Maybe they can start test-firing those at around the same time that Amazon starts doing same-day lunar deliveries and SpaceX opens up tourist visits to breathe freshly-terraformed Martian air.

The SLS frankenrocket cost billions to redesign to fit.  If you are going to build a frankenrocket, look to Orbital and their success with cobbling together surplus ICBMs and modified Pegasus final stages.

Artemis II requires at least a 20 month minimum turnaround because it's reusing Artemis I's avionics.

Assuming a March 2022 launch of Artemis I, that's pushing A-II towards 2024.

Is this a recently released render? If so, it's interesting how their placeholder lander is still included.

Yeah. I see why they couldn’t use the selected lander, as Starship has a way of dominating the image and that’s not meant to be the focus there, but they could have just left it out. Looking at the Flickr page, it was uploaded today, but I’m not sure that’s where it first appeared.

More Canadian Artemis news...

https://www.canada.ca/en/space-agency/news/2021/05/canada-moves-forward-with-plans-to-explore-the-moon.html

Highlights: Canada to send develop and send a yet-to-be-designed rover to the Moon within the next five years. Also plans to develop and test other lunar science equipment. 

Sigh. And there’s the old-space contractor developing C3: 

$23 million just to establish technical requirements. Must be related to AJR

But if SpaceX offers and NASA agrees, Dragon XL could probably be replaced by Starship/LunaShip. Or XL will be delivered inside a Starship

XL in SS is more likely, there is no way gateway can perform station keeping in such docking position. Or maybe a trim down version of XL or even scaled-up XXL that's similar to ISS's MLPM. That will deliver and retrieve with cargo starships like how shuttle did in the past

I got some interesting additional info from inside Dynetics.

They had dropped the drop-tank design due to the number of safety-critical separation events. They were doing for methalox and they wanted to develop the engine in-house. But apparently they hadn't even decided yet whether to use pressure-feeding or a pump-fed design.

No wonder they got rejected if they didn't even have a concrete engine design.

Wow.

$253,000,000 to write a proposal, and they thought that was good enough?
