We all know the pictures of the astronauts on the ISS floating around. We also suspect that a lack of gravity is bad for the body as the muscles go weak and such.
Why don’t spaceships just rotate to cause the effect of artificial gravity through centrifugal forces?
For Artemis the laser data link back to earth was supposedly disrupted by people moving around in the capsule- that’s how directional it is
microwave datalinks might have beamwidths of perhaps fraction of degree, but it’s still not much
