I think the average person gets it right. It's a nice feat to catch the booster and it will save money. But that's a side quest. The main quest of getting an actual load to orbit and beyond is still pretty far away. At least compared with the official time line where they wanted to achieve much more than that three years ago.
Um, no?
The rocket has been to orbit twice now, they've already demonstrated that. They're working on the bonus mission, landing everything and perfecting the hardware to the point where it doesn't need major refurbishment between flights.
As far as I understood it, SpaceX uses the word "orbit" liberally. If it reaches the hight where an orbit would be possible, that's "being in orbit" for them. In an actual orbit, the rocket would not fall back down again in an hour or so without active breaking. If my understanding is incorrect, I'm happy to be corrected. And even of that was achieved soon, it's still all without demonstrating that the starship could actually carry a load and return it safely. Not even an inexpensive dummy load. All SpaceX is showing in their live feeds are empty cargo holds that fill up with hot gases and fumes during reentry.
They've already demonstrated they can get it in orbit. The fact that they've not done it for this mission was intentional, not a limitation. They wanted the ship back, they didn't want it sitting around in orbit doing nothing being in the way. They don't actually have a mission for it yet, its mission is to prove that it works, so if they put it in orbit then what?
The whole point is that once it's in orbit it has virtually no fuel on board, because that's how they get around the rocket equation, they do fuel transfer on orbit. So in the testing scenario they would have a vehicle with virtually no maneuvering capabilities parked in a stable orbit more or less forever. Eventually its orbit would decay and it would uncontrollably into the Earth, which I think we can all agree is a bad thing.
