Launching multiple small satellites into orbit using magnets; is it possible? [duplicate]

Is it possible to use magnets to launch small light weight satellites into a orbit around the earth to provide a net like coverage around the earth? Is it practical and will it be useful?

Magnetic opposition for a launch boost [duplicate]

Just wondering since we are able to make an object seemingly float or neutrally gravity bouant, is it possible to create a launch pad where electromagnetism is used to "levitate" a vehicle (using ...

I'm confused on why we can't magnet idea to propel ship to space [duplicate]

when we put two magnets together they push each other apart. So why can't we use the same concept with the magnetic field and a man made magnet?

Why don't we use catapults to get to space?

Stupid question obviously. But did you ever had an idea which sounded so brilliant, but you know it is totally stupid? So, lets hear my idea: Do you know how we launch jet fighters from navy ships? ...

What technological hurdles prevent the development of a space gun?

Ever since Jules Verne wrote "From the Earth to the Moon" space guns have long been proposed as a method of launching objects into space. And for non-human, non-fragile payloads they make sense as the ...

Can you use magnets to travel through space?

My thought process is that there is very little friction in space minus gravitational pull. Which could be a good thing if you wanted to go faster or slow down. The question is, is it possible to ...

Is it possible to literally shoot something into space? [duplicate]

Regular spaceship missions are effective but also incredibly expensive. The most discussed alternative of them would be the space elevator, but with our current technology, it isn't possible to ...

Electromagnetic accelerator in space

Let's imagine there are already interplanetary spacecrafts and travel. Would it be possible to create electromagnetic accelerator somewhere in the outer space? It would work this way: There would be ...

What are the forces affecting superconducting MRI-magnet on low-earth orbit and could you accelerate a satellite with these forces?

In superconducting magnetic levitation the magnet levitates on top of the superconducting material (Meisner effect). In space, the electric current of the solar wind should create a magnetic field ...

What factors prohibit building a space cannon to launch raw materials? [duplicate]

I am envisioning a magnetic cannon to launch materials directly from Earth's surface to geosynchronous equatorial orbit. The parameters I have in mind are a near vacuum launch tube, about 10 km in ...
