>So the reason it went down under Obama was because the "Big Spending" republicans forced him to cut it.

Obama canceled the Constelation project without going through congress at all.

If you really want to fix the blane on SALT Ii, which I find acceptable, the dirty hands are Ronald Reagan's. Shrug. Yes, Dr. Dyson is on record as saying it's solvable. I deeply respect Dr. Dyson. I don't respect him enough to accept the assertion as the deed.

Bad enough he gave away everything they wanted starwars (orbital target acquisition) and FOBS banned. He gave them High Frontier. Jackass.

EDIT: Reagan, not you. SALT II is the reason we haven't tried using launching lasers. For just 1 thing.

Edit edit: A launch laser is an Orion with the engine on the ground. It needs really excellent targeting. Thie ship leaks fuel vapor into a combustion chamber. The laser fires. Rinse and repeat. Quickly. :-) fuel/air explosion. Get high enough you also bleed in O2.

You have to design a payload that can survive a nuclear explosion imparting the entire launch energy in an instant.

Sure, maybe you can launch a solid 100T block of steel. What do you do with that once it's in orbit? There's no space lathe to turn it into anything useful. Can you actually design a survivable vehicle to carry any other payload?

Assuming we have some reason to launch 100T blocks of steel into space, where are you sourcing them from? How can you transport them to the site? How are you going to load them into the gun? Does anyone need 100T blocks of steel in space right now?

How long do you think your barrel is going to survive repeated nuclear blasts for launch? How are you going to replace your barrel when it needs to be changed?

How much is it going to cost to build your gun? How many decades of launching 100T steel blocks into orbit, for which we have no orbital manufacturing capability whatsoever, will it take to make your money back?

If it's so hugely beneficial. It would be done or in the works but it's not? So we need to consider there are reasons. Your asking why it's not being done and I am giving you answers which your now saying are not valid. OK so your trying to argue thay the ISS is in desperate need or large steel structures? For what and how will it be assembled?

Water is a valid point but do you think designing an entirely new launch system just to bring water into space is economical.

"It's hugely beneficial for Artemis mission". Can you go into some details here about why Artemis needs to have a massive amount of stuff launched along side it? Does the mission not already have everything needed for success loaded onto a single rocket?
