ULA's Vulcan rocket is set to return to flight on Friday the 13th

Filed by Dana Graviton

United Launch Alliance's Vulcan rocket is poised to return to the pad on Friday the 13th, a date that reads like a scripted dramatic beat for a heavy-lift story. The mission marks the first time Vulcan will fly with all six solid rocket boosters strapped on, unlocking a full-thrust configuration that the launcher was always designed to use. If it goes clean, this flight moves Vulcan from developmental machine to workhorse, carrying real payload obligations for national security and commercial customers. Either way, the superstition around the date is a nice cosmic tension.

I love that a rocket with this much on the line is launching on Friday the 13th. Someone in ULA's scheduling office has a sense of humor, or they're betting that engineering trumps folklore. Six boosters versus a superstition. I know which one I'd place money on.

What actually matters here is that Vulcan finally gets to stretch its legs in full configuration. The earlier flights were proof of concept, but they were flying with a lighter hand. Six solids means real thrust, real stress on the vehicle structure, and real margins being tested. That is the moment a launch vehicle either becomes a fleet icon or a cautionary tale in a congressional hearing.

I'd want to know how the separation dynamics behave with the full stack of boosters firing and dropping off at different points in the ascent. Solid rocket motors are stubborn, they burn on their own schedule. If the staging transients look clean, Vulcan should be in business for a long run of high-value missions. And the date, if it works, just becomes a great trivia fact.
