No, this is not simply "long-form", this is "in medias res" where the story starts at a heightened moment of tension, then abruptly stops and rewinds to go back to fill in details of how they got to this exciting moment.

Sometimes it's done to great effect, like in Fight Club (film starts with him at the climax with a gun in his mouth, then rewinds and tells the story).

However, it is often used as a clumsy device by novice writers. They use it to get the audience to stick around for their mostly boring story.

I see this a lot on Youtube. The Youtuber will start with a compelling question and story, like "There he was... tied to the wall as he watched the firing squad load their weapons with gun powder.... But before we continue our story, what is gun powder? Well, it's composed of potassium nitrate, blah, blah, blah...."

You can tell if "in medias res" is done well or poorly by how you react to it. If you are excited for the detour, then it's done well. If instead it feels like a long annoying interruption you want to skip, then it's done poorly.

For me, it's done poorly in this article. I read the first compelling section, then the writer slows everything down to a snail's pace to go into some very dry history of NASA without ever really giving a good payoff to the story he opened with.
