Cheap bulk launch is a prerequisite, just like it is for lots of cool big space projects.

The "single biome planet" thing is a storytelling convenience, not an exobiological model.
It's like the "planet of the hats" where everyone wears specific hats: there to clue the viewer in rather than actually address timey-Earth millinery or Mirror Universe goatees.

Yep, this is how it will work. A chunk of each launch permit fee goes into a clearance pot.

Sun-impact trajectories take a lot of propellant. Burn 'em up on re-entry instead!

Just to be different, I'm keen to see Boeing's Starliner finally complete it'ss crewed flight test in April and enter ISS service. More suppliers are better.

The ring will have its own urge to turn into moons, and if has lots of mass, that moony limit will apply.

Methane is having its moment in the sun. Burns cleaner than kerosene (which is important for reuse), easier to handle than hydrogen, not as ghastly as hypergolics or hard to stop as solids.

So if we could see in the frequencies that radar sees, we would see the radome as a transparent bubble? Neat!

Just to add, cardiac drift will also increase the heart rate later in a long-ish session.

Magnetism doesn't have the range, and most satellite stuff isn't magnetic anyway (steel is heavy)

Still needs an order of magnitude more bulk, more cheapness. Starship is one to watch.
