Big things happening at Stennis this week too! Aeon R Gas Generator lit up the night, going full power for the first time. 🔥

What is Boeing going to be doing? No one has said. Theoretically, Boeing can claim prime work on the US orbital segment of ISS, Starliner, and SLS's core stage on its c.v., but this only highlights why they're likely to be a detriment, if anything, for reasons which will be obvious to everyone here. Almost all of ISS's development work dates back to before the McDonnell merger, and it's ancient history anyway at this point; the less said about the other vehicles, the better. It is telling that Boeing's Appendix P proposal for HLS was so poor that it did not even make the first round cut.
Doesn't Boeing run the ISS? Their operational knowledge about running space missions could be quite useful.

Development and operations are completely different, and the people doing operations are unlikely to be the people you want on a development team due to the differences in skillsets required for both.

Dragon has abort modes and an inherently safe method of EDL (doesn't require a liquid propulsion system to work).  And it's still not safe enough for the general public.

Something to bear in mind:  Commercial human space is operating under a "learning period" regulatory moratorium, enabled by multiple extensions to the legislation that originally established it.  That moratorium may easily be extended yet again, but it's currently set to expire in October, 2023.

At some point, it's going to expire for real, and there will be regulations that all commercial human systems will have to meet.  I would expect those regulations to be fairly forgiving compared to aviation regulations of any sort, but I wouldn't be surprised if they adopted NASA's 1/1000 pLOC for each of launch and EDL, and 1/270 pLOC for a six-month mission.

The scaling is a bit too good.  The team didn't want to overpromise and the performance at larger dimensions doesn't seem to degrade enough.  Credibility becomes strained if the performance is too much out of the ordinary.


That is very sad.   the incentive system you dealing with is upside down and backwards
Strange isn't it?  There is a real risk of failure.  Although Slough demonstrated elements of the wind driven magnetic sails in the laboratory, there is some significant pushback against the very fundamentals of the idea.  And the history is not perfect, the minimagnetosphere concept (M2P2), for example, that was based on the same basic theory, was flawed and could not work.
It's sad that there is no desire to actually test the possibility, as there would be significant applications if it worked.

[...] being the sole provider of methalox in cislunar is a pretty big deal, likely with [...] extremely good profit margins

Being the customer of a monopoly provider involves some pretty extreme tolerance to price distortions. The "market price" of a commodity tends to be just above the cost level of the second most efficient provider....

Sorry to break the conversation.... but.... does anyone know what is happening with the development of the landing barge for New Glenn?

i love how a bit of the focus is on unity , going to space is going to take all types and if any of us want to go there we have a lot to set aside in order to find a way to live amongst the stars and other planets.

As is FH can't delivery propellant to lunar orbit . Upperstage can't  survive 4 day without extensive modification. Might be able to build tanker based on Dragon XL bus but why would they if SS is their future.

Most US only have life of few hours, Centuar and SS are about only stages capable of multiday missions. Photon is more of kick stage/OTV than US.

That's a fair point, and it would be a problem that SpaceX would have to be willing to solve if they wanted to sell a "guaranteed prop in NRHO" kind of contract--for an App. P bidder or anybody else.

However, it's only about 60-80m/s from a BLT to NRHO.  That's not nuthin', but a couple of Dracos and 400kg of prop would handle it easily.  I don't think that Starlink bus propulsion has enough thrust or delta-v to work on a 15t payload as-is, but maybe there's a Draco adaptation that could piggyback on its bus?  (Remember, this is likely the kind of thing that SpaceX will have to do to market Starshield effectively.  This wouldn't be a terrible demonstration project.)

Obviously, SpaceX would rather not build a slightly maneuverable 15t wet methalox tank for FH.  But being the sole provider of methalox in cislunar is a pretty big deal, likely with multiple customers (NASA, SLD/SLT providers, USSF, and probably other allied agencies like ESA, JAXA, CSA, etc.), and extremely good profit margins--as long as Starship is doing the delivery.  If the price of that is a guarantee to get prop to cislunar on an FHE if something goes horribly wrong with Starship, that might be worth the cost.
