I wanna swap and be in the traveling backwards group for a bit, if that's ok.  Well, I’ve been traveling forwards for forty years now, and it pretty much sucks.

Seriously, there are some options available, but the structural requirements are significant and failure modes become much worse. For example, it is easier to control a fire in microgravity where convection can't start. One option is to build two vehicles connected by a cable. The difference in the gravitational field along the cable provides real gravity in both parts of the system <b>but</b> if the cable breaks then the bottom component will drop towards Earth and the top component will fly up towards the Van Allen belts. I am unsure which is worse... Yeah why doesn’t NASA do that?

Every time you turn over Coriolis effects will mess with your inner ear. If you are going to have artificial gravity then use it for working areas where people need the exercise anyway.

I think it would extend the workable lifetime of long term astronauts by 1/3 to 1/2 the amount they could normally work. Who do I have to contact to get someone at NASA to look at my idea?
