Missions needing artificial gravity

Before going beyond Luna or for staying in Earth orbit working in a tourist hotel, artificial gravity using centrifugal force must be investigated and developed to counter possible bad effects on balance. Bigger rings at lower G may be our best bet for now.

The best first mission to Mars and any mission to Venus or a gas or ice giant should be a ringed station. Call it Orbital JPL. Such stations can do measurements and send probes into atmosphere or, for Mars and Luna, do what Gateway is planned to do - but with gravity and shielding.

If we cannot make this work, there is no reason to continue with manned exploration. Even unmanned missions would be a waste of time. A large station in Jovian orbit, however, would be worth the effort.
