These are major problems when there is small spacecraft or space station like what has been used for the last 60 years.

Space station designs since the 1960s have known that building large spinning structures can simulate gravity.

The Kalpana One structure is a spinning cylinder with a radius of 250meters and a length of 325m. The population target is 3,000 residents. Kalpana One has been designed in detail by Al Globus et al at the National Space Society.

The London Eye is a Ferris wheel with a diameter of 120 meters. The London Eye weighs 2100 tons.

Gravitrons are cheap and common amusement park rides that spin people. However, the Gravitron is just proof that one-gee is easily simulated. The actual gravity loops would be made big and comfortable like overnight sleeping cars on trains. Also, Boring Company electric tunneling machines will make digging tunnels insanely cheap. It is almost as if Elon Musk has thought about the need for cheap tunnels for space colonies on Mars, the moon and elsewhere.
