Using projectiles to reach orbit.

It is possible with todays technology to launch projectiles into LEO using a large cannon that will give the correct muzzle velocity to escape earths gravitational field. Humans will never be launched in this way but supplies like water and food can be as well as simple parts and raw materials like alluminium and different metals that could be used in construction. These would all have to be enclosed inside a very strong shell that can withstand the heat and g-forces that go with a launch of this kind.

Is there some kind of international treaty on how large these guns can be made? Why else would an idea as simple and relatively easy to build not be taken seriously or be built for that matter.

Regarding the G-forces and sensitive equipment of the satellites:

Nanotechnology and MEMS starts delivering sensors and circuits that can stand tremendous high G forces. Emerging nanoexplosives could add some extra muscle to your gunlaunch while reducing the costs.

Meanwhile I would think that a gun is worth researching for the purpose of shooting capsules containig liquid propellant/oxygen etc to be captured by freighter in LEO and further transport/relay it to a spacestation.

I don't say its a cakewalk and I am sure you would have to throw many buckets of money at it, but I would think it is worth trying...

Such superguns would be able to deliver all kinds of nasty stuff to your average rogue state on the other side of the globe l, so they would become matter of discussion in ICBM treaties as well i guess.

One of the best aspects would be the amount of stuff u could shoot up into space (provied the gun doesnt need excessive maintenance) it could make room for much more important equipment on the shuttle just by it not having to carry tons of food and supplies.

A few years ago, NASA funded a program where a vertical lasar was being used on stainless steel saucer rotated at high speed.

In a few months it had to be moved out doors due the height that was being achieved. Not sure if the project is still running.
