Less than half an hour to the final flight of the Delta family.
It was a workhorse for decades, but it’s now obsolete technology.

I thought for a second I was looking at a stealth rocket. Then I noticed the countdown clock at T+9m lol.
Ad astra D-IVH. It was a good run.
And then there were two: SLS and the Centaur upper stage (RS25E and RL10).
Along the lines of cramming angels on pinheads, wither the fate of densified LH2?
Outside of launch pad tank storage at LC-39B does anyone think this work will expand to the two remaining rockets?
After all, taxpayer money is free money…
Bezos uses hydrogen for the New Glenn’s upper stage plus for in space and lunar use.
I still think SLS should have been called Delta V. The perfect rocket name.
OK, I’ll tell the waiter that the veal was your suggestion.
“Bezos uses hydrogen for the New Glenn’s upper stage plus for in space and lunar use.”
Which should be great if we ever get back to the Moon since as we all know is made up of mostly gas…

Wasn’t Delta IV basically obsolete from the get-go? A hydrogen-fueled first stage was a suboptimality necessitated by the US’s post-Saturn neglect of hydrocarbon-engine technology.
I think the precipitous post-Apollo NASA budget cuts resulted in the engendering of a sort of “poverty shock” mindset in the agency that still persists. Among the knock-on effects was the pervasive tendency to cling like an abalone to what projects were still on offer even when budget limits resulted in the making of design compromises that would ultimately prove disastrous down the road. At the same time, no such thing afflicted the legacy contractors which never really adjusted to the passing of the cost-is-no-object days.
Aptly put, Dick.
