Is it just me or is that headline impossible to parse? I have read it several times and still I have no idea what it is saying.
I think I found the definition of rocket that makes sense: "(UK slang, originally military) A severe reprimand; a telling-off. [from 20th c.]."
The decoded headline would be: Texas construction workers tell off SpaceX. Or just Texas construction workers place lien on SpaceX.
I agree that it's horrendously written and really forced.
i.e. "seriously get SpaceX moving (hopefully at speed) on the issue of unpaid bills"
