Why not actually make rockets – i suppose they would have to be teleported from sub-moon space to mars orbit at a point but there are 2 existing things that come to mind this could be based on:
- https://github.com/stujones11/meshnode – this essentially allows to build vehicles out of nodes
- https://github.com/aerkiaga/nodeverse/tree/main/mods/nv_ships – the rocket part of nodeverse – last i checked it did somewhat work already
Or even better you could have a launch pad where you can configure the trajectory so you end up in a specific space dimension / layer
