While SpaceX’s reusable rockets have slashed satellite launch costs to US$3,000/kg, some scientists have estimated that an electromagnetic space launch system could drive those costs down to a mere US$60/kg.

China completely invalidating SpaceX’s business model would be hilarious.

NASA is banned from working with China, so it would be genuinely hilarious if they were the only group stuck paying $3k per kg.

I’m not sure what’s funnier. If China open sources the technology and NASA would have no choice but to switch to it, or they keep it proprietary and force the US to use spacex

I think the funniest outcome would be Elon being forced to try to build a space gun to try to compete.

The SpaceX rockets being reusable barely put a dent in the price of launches, they were already cheap. probably has something to do with them using RP-1 fuel wich is is cheaper and easier to store and creates greenhouse gasses vs. the clean burning liquid hydrogen that NASA and ESA use.

the answer to every infrastructure problem is high-speed rail

I hope they figure out how to do this with engineless commercial airliners (I know it’ll never happen but it would be cool)

Fuck it, I see no reason why a train couldn’t be shot between two tracks 100 miles apart

Well, you could make a “train” to orbit but your rail would have to be hundreds of kilometers long, dozens of kilometers tall, held up with wires and particle accelerators, and the train would probably just be a single car

Btw this would just accelerate the space plane so it doesnt have to burn as much fuel as otherwise. It’s not a literal train into space

Look up launch loops if you’re interested in trains to space

Its not a new idea, arthur c clarke wrote about a rail launcher in Prelude to Space (1947), he based most of that story on how the scientists at that time expected space travel to happen.

No rail launchers arent new, they just havent been invested in for space travel. At a guess id say because they are expensive and end up stuck in one place, which adds limitations later on

bringing a science fiction concept into reality presents an engineering challenge that requires both research and innovation; research to find what the real life problems stopping you are, and innovation to solve them

By this definition innovation only exists as fictional writings
