Why are there no rotating space stations?

Science-fiction space stations simulate gravity by rotating. The International Space Station doesn’t spin because it’s used for low-gravity research. The International Space Station is a one-of-a-kind lab-oratory for a specific reason: microgravity.

Will SLS be obsolete?

The SLS has cost many billions of dollars, and NASA proposes to launch for the first time in February 2022. NASA would like to commercialize the SLS, fly it once a year for the Artemis Program, and pay half price for the privilege.

Why do you think building a spinning spaceship wouldn’t be practical?

The bigger the disk, the slower you can rotate it. “This would avoid having a large gravitational difference between your head and your feet, which would result in blood accumulating at your feet and making you feel light headed.

Why doesn’t the International Space Station rotate?

No microgravity would more or less render the ISS unnecessary from a scientific point of view. Therefore it was never intended to build a whole rotating space station. Of course money is a second reason (it always is a reason), but if money is a real concern, the ISS would’ve never been built.

How difficult is it to create a rotating spacecraft?

Let’s say we two separate sections at a radius of about a 1000 feet with the fuel tank in the middle (the non-rotating part). Well, creating a rotating spacecraft is simple in theory, but extremely difficult in practice.

Could artificial gravity be generated by a space craft?

Spacecraft rotating to generate artificial gravity through “centrifugal force” are commonplace in science fiction but not in reality.

What would it take to build a perfect space ship?

It’d have to be assembled in space. Meaning you’d need a permanent space station in Earth orbit. Furthermore, the design of the ship would have to be “perfect” since even the slightest asymmetries in the mass distribution would be difficult to deal with.
