This is a big achievement for both Blue Origin and spaceflight in general in the area of reusable spacecraft, but my count that makes the 4th launch system that puts commercial, scientific, or military payloads in space with a large portion of the stack being reusable:
- STS (Shuttle orbiter and SRBs reusable)
- SpaceX Falcon/Falcon Heavy
- SpaceX Starship/SuperHeavy
- ....and now Blue Origin New Glenn
Blue Origin being able to "return to launch site" as SpaceX has in the past also shows that this technology is not confined to SpaceX, which is good for everyone.
Other nations and private companies are also working on reusable systems including have hardware built, some even flown and recovered (but without reflight yet). These are great developments for spaceflight as a whole.
Congratulations Blue Origin!
