artificial gravity a different idea...maybe?

For healthy space exploration and habitation you need 1 g

There's plenty of evidence that 1 g is sufficient (assuming
a normal healthy life style, not confined to bed), and 0 g
is not sufficient.

Between 0 and 1 g, there's no data. Except for a few man-days
on the moon, there's virtually no experience of living in
partial g. Probably, something less than 1 g would suffice,
especially if coupled with appropriate exercises and other
countermeasures to deconditioning. But nobody really knows.

Billions of dollars have been spent on microgravity life science,
looking for such countermeasures, with very limited success. I
wish some portion of that budget would be invested in a real
space-based artificial-gravity test bed.
