What if we make the shielding once, put it in orbit and "borrow" it for each ride. Launching it from surface is expensive, between planets not so much. Even bet

What if we make the shielding once, put it in orbit and "borrow" it for each ride. Launching it from surface is expensive, between planets not so much. Even better, ship it in parts on the small reusable rockets that we already have. It's about time we start making stuff in space, welding a metal box seems like a good first project (also no shielding gas required)
