“Blemish” on Orion hatch’s “thermal barrier” delays countdown rehearsal
According to a report yesterday, a countdown rehearsal two weeks ago for the Orion/SLS stack that also included the four astronauts to fly on the next mission was delayed because a “blemish” was found on the Orion hatch “thermal barrier.”
“Prior to the countdown demonstration test, the agency had planned to conduct a day of launch closeout demonstration. This demonstration was paused when a blemish was found on the crew module thermal barrier, preventing hatch closure until it could be addressed,” the statement read. “A repair was completed on Nov. 18 allowing the closeout demo to successfully complete on Nov. 19. To allow lessons learned from the closeout demo to be incorporated into the planning for the countdown demonstration test, the decision was made to proceed into water servicing next and place the countdown demonstration test after this servicing completes.”
It was not clear from the NASA statement how a ‘blemish’ prevented the closure of the hatch and NASA would not say exactly when the countdown rehearsal will take place. Declining to provide further details, the space agency spokesperson said: “NASA remains on track to launch Artemis 2 no later than April 2026 with opportunities to potentially launch as soon as February.”
NASA released no additional details, though it claimed this delay will have no impact on the launch schedule for the Artemis-2 mission, planned for launch no later than April 2026.
The lack of detailed information from NASA is disturbing. What was the “blemish?” It appears it was on the rubber gaskets that circle the hatch’s edge. What caused it? Was it some damage? A production flaw? NASA’s general silence forces us to consider more serious possibilities.
I continue to pray that these four astronauts are not going to end up as sacrificial lambs to the political scheduling demands that is forcing NASA to push on blindly, as it did with both the Challenger and Columbia failures, ignoring or minimizing issues that common sense should never be minimized.
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 or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
