Spaceships: Escape to the asteroids

[johndallman]

How long will it take for a resupply mission to be set up and dispatched? How solid are their consumables and recycling for waiting rather longer than that? How confident are they that this will happen?

Your plans for colonising the asteroids, in recent threads, seem to rather under-estimate the deadliness of a space environment. Recall that getting stuck in the asteroids is rather worse, for example, than being marooned in the Antarctic circa 1900. In the Antarctic, there's unlimited free air and water, food to be hunted for on the coast, and boats that can be sailed without needing external fuel resources. In the asteroid belt, you have none of these things.
