Here's a thought: maybe safety has something to do with the curvature of
space-time (or whatever) ... so that being under 0.0005G from the sun
doesn't make that much difference. This idea would take some mathematics
to check out -- it's relatively early in the AM here so I haven't checked
it out. If I'm wrong, no doubt somebody will flame me (bear in mind I'm a
retired civil engineer, not a mathematician :-)
