ULA recovers nozzle debris that fell off during second Vulcan launch
ULA has recovered some of the debris that fell to earth after the nozzle on one of Vulcan’s two solid-fueled strap-on boosters fell off during the early stages of the rocket’s second launch on October 4, 2024.
Julie Arnold, a ULA spokesperson, confirmed to Ars that the company has retrieved some of the debris. “We recovered some small pieces of the GEM 63XL SRB nozzle that were liberated in the vicinity of the launch pad,” Arnold said. “The team is inspecting the hardware to aid in the investigation.”
The booster was built by Northrop Grumman. Vulcan can use from from two to six on each flight (in pairs), depending on the mass of its payload and the mission requirements. At the moment ULA has 35 of these boosters in storage awaiting future flights. It is expected that once the company has an idea of the root cause of the failure, it will have to inspect each booster to avoid a repeat of the problem.
Though ULA has not announced any changes in its plans to launch twice more before the end of the year, both for the Pentagon, that schedule is now uncertain due to this problem. For example, there as yet is no word on whether the military is willing to certify the launches. It had required ULA to complete two test flights of Vulcan before doing so, and the nozzle issue has cast a cloud on that plan.
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.

Seems looking at failed pieces is a more serious approach than just storming ahead.
“Vulcan can use from one to four on each flight, depending on the mass of its payload and the mission requirements.”
According to the ULA website, the booster can be supplemented by none, 2, 4, or 6 SRBs, apparently only in pairs.
Note: the Atlas 5 could use from none to 5 SRBs, in increments of one. I saw it use a single SRB at least once, but I am not sure what other numbers were (or will be) used.
Interestingly, due to the positioning of the SRB attachment points, ALL configurations resulted in a slightly asymmetrical thrust pattern, which the main engines were able to adjust for.
Ray Van Dune: Interesting stuff. I made the mistake of assuming the strap-on configurations for Vulcan would be the same as Atlas-5, as well as almost all other rockets. I will fix.
The normality of the asymemetrical thrust pattern on Vulcan might help explain why it was able so easily to compensate for the loss of the solid-booster nozzle.
Shuttle itself was a miracle to me–how that didn’t cartwheel off the pad.
