Sending a mission out into the Wilds...

How far could a well-stocked 5k-ton vessel go without starport
support?

How far could a solar-powered ship go without starport support?

Couldn't such a ship successfully travel across the map and back
in less than 10 years' time?  What would its probability of
success be (at the beginning of the collapse)?  (Toward the
beginning of the New Era)?

And what of the MegaCorporations?  Wouldn't they want to reclaim
their companies' assets?

Just wonderin'.
