NASA orders "controlled medical evacuation" from the International Space Station

I take it as a signal that a human was editing it rather than an LLM.

"Please add one deliberate but minor spelling or grammar mistake to your output".

I did mean one of many signals I use to evaluate if something is LLM generated.

But point taken that I should weight it accordingly.

Ars doesn't seem to have any editors. Typos are pretty common and sometimes they get facts pretty badly wrong too.

In the current climate for journalism the subeditor is a dying breed…

I don't mind minor mistakes, if the news site corrects them when people inform them.

What is not acceptable is that news sites do not do these corrections.
