>>13288984>>13288991Orion is a meme, you only like it because the concept or riding nuke sound cool.
It's the best example to warn against single point of failure, you can't put any redundancy in it and most of it's failure state will annihilate the ship and the surrounding area without a saving chance, firing its engine is more dangerous to itself than even nuclear light-bulb.
Even if it was technically as simple as fanboy claim it's unpractical, it will never ever be launched from the surface which was the only thing going for it as it's less efficient than other engines.
The ship can hardly be throttled or vectored, it's manufactured nukes aren't good for ISRU, they need even better protected storage and yet the mass requirement also ask for each bomb to be shielded as lightly as possible.
>>13289033Its a launch vehicle, plenty of other concept can outrange Orion with or without ISRU from planet or asteroids.
If you could make Orion you could make plenty of other nuclear engines capable of constant thrust with better efficiency.
