The pictures look cool!
But I get the impression that running a cool show becomes more important than the actual development work. What unsettles me is that this design again shows significant differences to its predecessors in aerodynamics and engine arrangement. While these design features keep changing, any prediction of a first flight - manned or unmanned - is wish-thinking.

I propose the new design should come in two colour schemes to chose from:
- A green Planet Express ship, and
- A red-white Tintin rocket.

I don't think it's any worse than Shuttle.

Not sure, the fins at the tail don't appear to be well suited for a good AOA, it rather looks like its going to go down nose first like a lawn dart.



Also, I doubt they would be easily heat protected, if they are so exposed to undisturbed airflow.



It rather looks like one of those studies that look better than they fly.

Articulated wings, what happens if they do not unfold in the reentry,
or only the one on one side?

Could become a hard landing. Also, how heavy is the mechanism supposed to be for moving the wings and withstand the lift force?

Thanks for adding the Banana size reference!
Much more modern than those "old-fashioned" imperial or metric measurements

And damn, what a time for a live cast, completely hostile to poor German PLM specialists with a serious case of caffeine withdrawal...

My understanding is the wings actuate to account for different AOAs.

How? They are far away from the CoG and move the CoP far back. Unless they fold completely inside the rocket, they should be pretty disturbing. Even a small box shaped section at the end of a tube has that effect at high speeds, though much less than folded down wings.

It's gonna take longer than 2024 for us to get to Mars. I hope not, but I agree with most orbitnauts on the thread. I believe the proposed design is still a little rough atm but I believe Elon Musk will have something better presented soon.

If they succeed, they will ridicule the Orion project based on the concept of the 60s
