But can it ever hope to compete with SpaceX?
Like the Falcon 9, Adeline is only partially reusable -- but the way it's meant to work is quite creative. While most of the rocket's fuselage goes unrecovered after launch, the bottom portion of the rocket housing the main engine (most expensive part and arguably the most important) is designed to safely return back home. The design calls for the first stage of the rocket to come equipped with wings and propellers, allowing it to travel back to Earth like a small plane and land gently on a runway.
The key difference between SpaceX's first stage recovery concept and the one Airbus is pitching is fuel consumption. SpaceX is trying to save each Falcon 9's main engines and fuel tank by autonomously landing much of the rocket's fuselage on a drone ship in the middle of the ocean. (The company is getting pretty close to making that happen, too.) But to do this, SpaceX must load the rocket with extra propellant before liftoff; this leftover fuel then helps to guide the first stage back down to Earth gently during its descent.
Airbus says its design drastically cuts down on that extra fuel needed for landing. Adeline's first stage is much smaller than SpaceX's and detaches entirely from the rocket's fuel tank. Instead of using fuel to guide itself back to Earth, the first stage will travel on a ballistic path using its tiny wings and propellers. It will then land horizontally on a runway just like an airplane. Airbus claims less propellant is needed for this technique, and therefore each launch will cost less.

Sweet
Adeline
Spacex wins on account of having a better graphics package.
The Shuttle looked cool but was a flawed idea.
We should have developed a version of the Saturn 5 that had recovery of the most valuable parts to save $$$
The Saturn 5 would be nice to have now for Mars missions.
on tiny wings and fairy glow..

I wholeheartedly agree — the Saturn V was going to be VonBraun’s Mars mission booster, but of course LBJ’s huge-assed war in Vietnam and fake war on poverty blasted that idea to hell. There’s been intermittent interest in restarting F1 production, including recently, and I’d love to see that. 1.5 million pounds thrust at sealevel (per engine), developing to 1.7 million while under way...
Meet Adeline, Airbus' Answer to SpaceX Reusability
vs.
hence the smiley. :’)
Soooooo what happens to the fuel and oxidizer tanks?
Do they make it to LEO where they could be re-purposed as living volume, or do the fall back to earth and burn up uselessly?

The design calls for the first stage of the rocket to come equipped with wings and propellers, allowing it to travel back to Earth like a small plane and land gently on a runway.The rest of it tumbles back / burns up / smashes into the ocean.
(I'm inclined to make the same inference)
Carry on then.
PWC is moving ahead with the F-1B to replace the Russian NK33s, last I heard.
Ah yes, another viewgraph spaceship. Pictures are easy; flying hardware is hard. Come back when you’re bending tin and blowing stuff up with it.
Thanks, good idea for a separate topic, as well.

The key difference is SpaceX is actually doing it. It’s more than vaporware.
