magbeam spacetugboat SPUG

a space tugboat powered by a magbeam satellite

the idea of a magbeam to power interplanetary spacecraft has been around for a while. the beam satelite has the energy and sends it by very concentrated plasma beam to the traveling craft that uses a magnetic field to sail the beam toward its target.

i think this idea is good but why not first test it out on a small craft that orbits the planet and is contracted to tug other satelites around. moving satellites requires much energy, usually in the form of rocket propellant and sometimes when satellites run out of fuel, it's sadly too costly to keep them running by refueling them. i think a space tugboat could make it economical to alter and relift satelites orbits at a moments notice.

the magbeam sattelite is a large powerfactory gathering sunlight and all other possible energy ( possibly even powered from an earth based radio wave platform ) . then it sends all aggregated / stored power to the spug which is a small craft that can float around the earth and is designed specially to hook onto or otherwise grab other sattelites without damaging them. the spug might even drag these craft to better orbits for fun! just as charity to demonstrate that it works well. ultimately, the spug could be used to pull very low earth orbit object ( such as micro sattelites) from 100 miles up to higher stable orbits.

right now balloons can get up to 25 miles reliably, the international space stationg floats up at 200 miles. if we take a ballon and put an amateur 2000 dollar rocket on it, we can get it up to 80 miles. for 10g's we can get it up at 100 miles. with a space tug, we can just haul it up to 200 miles. so i'm saying we do this spug right. zeev

       The craft can only travel in the direction of the beam so SPUG would have to in a higher orbit than the beam satellite. I guess you could get SPUG to return to a lower orbit if you throw the object its towing outwards, otherwise you'd need a second satellite in a higher orbit to push it back down. Also, isn't there a force on the satellite as it emits the beam?
