Unexplained issues with assembling SLS’s core stage?
It appears that in its effort to finally assembly SLS’s core stage so that it can be tested prior to its first launch, probably in 2021, NASA and Boeing recently experienced an issue that required “corrective action.”
Neither NASA nor Boeing have provided any detailed explanation for what the issue was, but according to the story at the link,
…one source suggested to Ars that Boeing technicians are having difficulty attaching the large rocket engines in a horizontal configuration rather than a vertical position. NASA and Boeing made a late change to the final assembly process, deciding to mate pieces of the core stage horizontally rather than vertically to save time. However, this source said horizontal mating of the engines has created problems.
Despite this, NASA officials said progress is being made. “NASA and Boeing are expected to have the first engine soft mated to the core stage next week,” Tracy McMahan, a spokesperson for Marshall Space Flight Center, said on Saturday. “However, there are many steps in engine installation that have to occur before the installation is complete.”
I applaud them for finally trying to “save time,” a concept that up until now the entire SLS project has never had much interest in. That this effort ended up causing a delay however is symptomatic of the design of the project, which remains cumbersome and inefficient, a fault not of the engineering but of some fundamental decisions at the top by Congress and NASA’s management.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

How would it feel to be working on SLS when you can see Musk racing ahead?
