A space platform rail gun would be much better.... and cheaper.
“A space platform rail gun would be much better.... and cheaper.”
Why do you think that? I would think the weight, power generation, and logistics of reloading it with projectiles would make this ultimately more expensive.
I’m interested to hear what you think a cheap version would look like. It could be as simple as sending up a bunch of rods in a barrel, so to speak, where the rods are targetable. Still, weight, etc.
