That’s a very optimistic headline. They haven’t made any orbital launch attempts, as far as I can tell.

The whole article looks like it was written by an amateur space journalist that has no idea what is going on in the industry, but falls for all the marketing.

Also: getting up is easy. The hard part is getting fast enough so you don't fall down again. So you still need quite some fuel no matter how high you can throw.

BTW: Spinlaunch knows this of course. They plan to sling a rocket into space to get the payload to orbital speed. Funny that is not mentioned in the article.

Yeah, when I first heard what they are trying I was extremely sceptical. Watching some YouTube videos that talk through the physics involved didn't help much. So I was extremely, surprised reading this headline and thinking they actually got something into orbit. I'm somehow both relieved and upset that they didn't.
