this looks about right for CBM scaled bulkheads.
bottom half of the bulkhead will become passthroughs, allowing power, data, and fluids to pass from one element to another, including between Axiom hub and ISS."
Axiom engineers are relying on an innovative thruster powered by oxygen and methane to propel Axiom Hub One to the ISS.
Axiom Hub ... is 60 feet long by 15 feet in diameter and weighs close to 60,000 pounds.
They will get a boost into space from a SpaceX or Blue Origin launcher
Stumbled across the Ansys (engineering simulation software) blog featuring Axiom.There were a couple interesting tidbits with new (to me) information:Methane / O2 ThrustersQuote from: https://www.ansys.com/blog/axiom-space-is-using-ansys-simulationsAxiom engineers are relying on an innovative thruster powered by oxygen and methane to propel Axiom Hub One to the ISS.This one is a headscratcher to me. Understand that this design is engineering for the future but I don't believe that cryogenic fuels / methane has been used for long term station keeping propulsion before. They will need to nail cryocoolers, the thermal design, manage boiloff, verify their sabatier design, and much more on their first orbital module.Alternatively, (because of the distributed nature of the propulsion system and low thrust needed) I guess you could get away with a gaseous only pressure fed system and eliminate the cryogenic concerns. If you break it down, the only new thing they are doing is just capturing a waste product of their ECLSS system (which is fully implemented already [up to the methane capture bit] in the current ISS ECLSS configuration today) so maybe it isn't that huge of a leap technology wise. Cryo or not then adds performance and difficulty to the setupThis design may also explain the embiggening of the service section of the modules (from tapered to cylindrical) Updated dimensions and massQuote from: https://www.ansys.com/blog/axiom-space-is-using-ansys-simulationsAxiom Hub ... is 60 feet long by 15 feet in diameter and weighs close to 60,000 pounds.LauncherQuote from: https://www.ansys.com/blog/axiom-space-is-using-ansys-simulationsThey will get a boost into space from a SpaceX or Blue Origin launcherI'm sure that the prime plan is to launch it on a Falcon Heavy fully reusable / center core expended. However, this is predicated on the extended fairing being ready and available to non military customers.Alternatives are:Starship with extra chompy chomper upgrade (due to how long this module is)New Glenn (if the Axiom module is really delayed or if BO gives them a sweetheart deal)Additionally, they seem to have not considered Vulcan Centaur Heavy with the Long fairing due to cost or availability. The mass and dimensions of the module line up nicely with Vulcan's payload capabilities.

2. This isn't a standard launch and would need to be ordered well in advance. Falcon heavy and extended fairing production is low and may be "booked" for the next couple years for NSSL launches / NASA (not available in the 2024 launch slot)
Two Axiom Modules at $129 million are now being fabricated in Italy.The article does not specify which two modules but I assume the two are directly connected to the ISS.https://www.thalesgroup.com/en/worldwide/space/press_release/thales-alenia-space-provide-first-two-pressurized-modules-axiom-space
Sorry for the confusion, but will PMA-3/IDA-2 be relocated so that the first Axiom module can be attached to Harmony's CBM? Thanks.
With @Axiom_Space set to start adding modules to the @Space_Station in 2024, I sat down with Axiom CEO/President & Co-Founder Mike Suffredini - former ISS Program manager - to talk about how this will all work and how the Axiom-1 & -2 missions factor in.https://www.nasaspaceflight.com/2021/11/axiom-suff-interview/
