But the F9 first stage doesn't get to orbital velocity, either, remember.

The achievements are comparable, despite the fact it makes SpaceX come second. Blue Origin was first with a VTOL rocket stage, as part of a space system.

It gets a whole lot closer (and is _much_ larger).

I really can't emphasize enough how much of a difference the ability to hover makes for New Shepard. SpaceX has been doing "New Shepard" type flights for a long time now (they didn't bother going that high, but 'high' isn't really that interesting, it's 'fast' that matters). However, Grasshopper (like New Shepard) was able to throttle down to a TWR less than 1. That makes landing so much easier (the rocket can 'stop' and get settled before it proceeds to land).


To give people an idea, this is the difference of scale:

Blue Origin's achievement is nice; just as older prototypes that achieved suborbital landing (Grasshopper, DC-X), but it's unclear yet what it meant for the industry (hope they keep going though, they're a good track). SpaceX's landing is a landmark for space travel, rapid reusability is now much closer. I'm much more confident now this will change the cost structure of the whole industry, seeing how launch is a dominant factor.


Sure, Bezos gets the "first rocket that went to 'space' and landed vertically" prize. It might even be cool sounding for the laypeople who really don't know what values 'space' can take.

But it's not what matters, in fact it's irrelevant, was not a disputed trophy, and won't be mentioned 50 years from now.


The huge difference is the Falcon 9 first stage is part of a system that puts a few thousand kilos in orbit, and it flys half a dozen times per year.

Getting to space is just getting high off the ground, its not very useful unless you can achieve orbit.


They're barely comparable. If at all. The F9 isn't at orbital velocity (although, much faster and on an orbital trajectory that has to be cancelled out). Sure. But the F9 was actually taking a payload to orbit. The Blue Origin never will, it's just a mega rich tourist toy.


Actually, I'm sure NASA managed that first a long time ago.

In fact, didn't they do it on the moon several times?

At any rate, John Carmack's Armadillo Aerospace managed it long before Bezos did. But wait, he didn't get to space? Hair-splitting.

At the end of the day, you could do what Blue Origin did with a balloon. The practical aspect of actually being able to put something on orbit is what's special.
