Giant catapult defies gravity by launching satellites into orbit without the need of rocket fuel

Sounds like a giant one of these:

Iirc spin launch does still use rockets, it just can use smaller ones by replacing the first stage with their spinny thing. In theory anyway

The title makes it sound like it already has put something into orbit.

Like everything else that the internet technosphere likes to breathlessly talk about, I'll believe it when I see it in action.

Just by the headline alone I can tell that whoever came up with this has zero understanding of orbital mechanics. Even if you manage to break atmo you still need reaction mass to circularize your orbit.
