>>14062517Spinlaunch exists. Mainly because
1. we don't really need to launch that many satellites
2. it's hard to launch a rocket out of a gun and direct launch where the rocket provides just enough for circularization requires ~1/3 of projectile mass to be ablative heatshield.
3. high accelerations limit the payloads you can use, but for stuff like satellites or just propellant it's fine

>>14062569Mass drivers are nice, but your entire post is retarded.
>>There are no materials that can build that on Earth.see the link above, it's feasible on earth
>> They are building one on the moon to create a logistic supply chain to Mars so they can mine asteroids of phosphorous so everyone that's retarded. No one's building any right now. Asteroids are not a good source of phosphorous. It takes HUGE amounts of energy to move mass between planets or even to LEO for that matter! It's easier to just extract phosphorous from rocks on earth at that point. Mining asteroids from Mars is straight up retarded because intercept opportunities occur less often and phasing is a bitch.
