Sorry I wasn't very clear.. Assume for a second the mass driver extends up past most of the atmosphere. Would it be possible to reach L1 With as little horizontal thruster burn as possible?
I was wondering, if a Mass Driver launching only vertically would be best used to attain escape velocity, or if it could be coupled with horizontal propulsion to reach an orbit around the earth.
(P.S. I apologize if this sounds a tad unclear and hastily written, I lost my original post)
