What if a space ship had the design input of submarines, with the use of ballast tanks to control the 'depth' of where is travels into atmospheres or closer to celestial bodies with a gravitational/electromagnetic field?
Might save on fuel used for takeoff and landings if it could be thoroughly controlled by computers

I'm not quite sure what you mean. ballast tanks work by taking on external water and flushing the water out using compressed air, so I'm not really sure how that would work without something to intake/jettison. could you explain further?

Maybe you mean like Hindenberg Floating Air Baloon? then on the upper Atmosphere they just blast rocket to ascend to space? That is like submarine isn't it? I also wonder if that's possible? If that's not possible maybe we can create baloon platfom to save fuel and blast rocket from that baloon platform?

Its not the 100 miles above the earth that is the problem, its getting up to orbital speed. The shuttle used 7% of its energy to get to altitude, the remaining 93% of energy was getting up to mach 25.
An electro-magnetic suspension system, like 2 north poles of magnets repelling, assume both are outside each other. I'm not sure how this would work so close to a celestial body that has a magnetic field, which precludes both the Moon and Mars.
