That seemed awfully high - so a little checking:

The NASA budget peaked at $5 billion in the mid 1960's. The 1967 GDP was $862 billion. So less than 0.6% of GDP. Still a lot of money though.

In addition to the other comments regarding the stupidity of the above, I guess you’ve missed the Falcon Heavy launches.

I mean they can put humans into space currently, the only other entity that can do that is the Russian Space program

Maybe it was 8% of the federal budget. I don’t know the exact numbers but it was really fricking high

According to Wiki, NASA exceeded 4% of the federal budget in 1965 and 1966, spending nearly $50 billion in 1966 in 2021 $’s. The comparison between NASA in the 60’s and SpaceX now was ludicrous.

He actually misspoke, as the proper comparison is to the Fed Budget

When NASA was all in on the moon

if you need it excavated quick... call SpaceX

we'll get you a hole dug in 15 seconds or less guar-on-teed

They were fortunate to not have debris blowback destroy the Starship before leaving the pad.

For you civil engineers, could this have been predicted? For you aerospace engineers, do 33 rocket engines increase the number of possible failure points?

Yeah this seems like it was kind of a "let her rip" kind of launch.

I've heard they are replacing the stand with a newer design anyway so it was scheduled for demo. But that crater isn't going to be an easy fix.

I wonder if the blowback debris contributed to some of the raptor engines not firing?

Those pictures that were posted do not look good for the foundation under the OLM, also there was evidence that some of the tanks in the tank farm were leaking cryogenic fluid. That would require them to replace those tanks. So all the tanks will now need to be pressure tested and those damages will need replacing.

Depending on the damage to the slab under the OLM, that can take months to figure out how to repair and complete the work . I do hope that gives them a chance to run plumbing for the deluge system and add in a flame diverter to alleviate future problems like this one.

I think it’s pretty likely that the pad is a 100% rebuild. That will take a while and will be pretty expensive. Obviously destroying the launch pad wasn’t part of the plan

What destroyed the pad? They’ve test fired the motors before right?

yeah but maybe the static fire tests never got to 90% thrust for as long as liftoff took

just guessing but the rocket looked like it spent much more time in liftoff than it was supposed to. And the fuel was dumping right off the bat

they fried it basically

take this with the pinchiest of pinches of salt...

someone in the chat on the NASASpaceflight 24/7 Starbase cam on YouTube said 1 of the engineers told him the hydraulic power unit (HPU) and thrust vector controls (TVC) were fully operational up to the moment the flight termination system (FTS) was triggered
