Reply to comment by saltywalrusprkl in China hoping rocket that can send people to the moon will be ready to launch by 2027 by Saltedline

Wouldnt the orbital hook still require propulsion systems to remain in orbit and yeah a line of Mass Drivers ringing the planet along the equator set up by all global powers was my thinking. This so there is always an optimal launch profile to hit the moon or any established orbit sought.

You’re definitely never getting a direct transfer to the moon using mass drivers. You just need one that can rotate to adjust its inclination, launch payloads into orbit and then perform a TLI burn to get to the moon.

Yeah, but this would be for efficiency memes. Less fuel to burn in getting to orbit would mean greater payloads. Thats what I thought the benefit of mass drivers would be.

It is, but you don’t need the mass driver at a specific point on the equator to gain launch efficiency bonuses
