Mission: Rendezvous with Rama

[Boersgard]

A mission where you re-enact something like Rendezvous with Rama - perhaps with an object like the one that recently passed through our own solar system last year: https://www.sciencealert.com/interstellar-extrasolar-asteroid-weirder-than-we-knew-oumuamua

I read the title and immediately thought of this

Hmmm.

@Aziz, if you're not aware, Rama was a book series by Arthur C Clarke.   Big (really big) tube thing comes through our solar system, and we fly up to meet it.   Hilarity ensues.   Good read. 

As to the OP, the mission builder might be where you want to look to create, and then share it.   I think there's limits to the physics engine that will limit the size of the Rama vessel, but you could easily put a large vessel on a similar orbit, and set up your rendezvous from there.
