Axiom to speed up assembly of its space station
Axiom’s new module assembly sequence
Capitalism in space: In order to be able to fly its space station independent of ISS more quickly, Axiom has rearranged the order it will launch some modules.
Originally, the plan was to attach Habitat 1 (AxH1) first, before the power and thermal module. Now, the on-orbit assembly sequence will start with the Payload Power Thermal Module (AxPPTM), followed by AxH1, an airlock, Habitat 2 (AxH2), and finally the Research and Manufacturing Facility (AxRMF). “The result – free-flight capability after the launch and berthing of PPTM,” [Mark Greeley, Axiom Space COO and station program manager,] explained, “[will allow] us to add modules while on orbit once we have separated from station. Our goal is to ensure a smooth transition from a government to a commercial platform, maintaining a continuous human presence on orbit to serve a community of global customers and partners, to include NASA.”
The AxPPTM primary structure will be built by Thales Alenia Space in Turin, Italy, and then relocated to Houston no earlier than fall 2025, where the integration of the internal structure and systems will take place at Axiom Space facilities.
The new sequence is shown in the graphic above. This change will allow Axiom to fly free two years sooner than previously planned, in 2028. It appears NASA pushed for this change possibly because it considers remaining attached to ISS until 2030 a risk that should be avoided. NASA apparently is increasingly concerned about the state of Russia’s Zvezda module, and fears it might have a catastrophic failure due to the stress fractures in its hull. The sooner Axiom can get free of ISS the better.
This modification also appears to include some major changes from previous Axiom graphics. It appears the airlock module and its solar panels have undergone a major design change.
Below is my present ranking for the launch of the four space stations being designed and built:
- Haven-1, being built by Vast, with no NASA funds. The company is moving fast, and plans to launch and occupy it in 2025 for a 30 day mission. It will then build its mult-module Haven-2 station.
- Axiom, being built by Axiom, which has also launched three tourist flights to ISS. Though there are rumors it is experiencing cash flow issues, today’s announcement suggests those rumors might be unfounded.
- Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. Though Blue Origin has apparently done little, Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building the station’s modules for launch.
- Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.

What is going to be the launch vehicle
Whoever they can talk down :)

HA HA HA!
I didn’t know you were such a comedian Robert!

Site says three comments but only two show. Wonder why?
M Murcek, I noticed a similar problem when checking to see if anyone had responded to any of my comments: My comments were not there. It’s something browser related. The same URL in Edge shows the comments fine while Brave does not.
Mark Sizer: Others have emailed me about similar issues of missing comments they can’t see. I block almost nothing.
I have emailed my web guy to see if we can identify the cause. It might be related to WordPress however, which we have no control over.
