SUMMARY

The discussion centers on the physics of rotation in different environments, specifically comparing rotation in a vacuum to that in a pressurized environment. Participants highlight the principle of conservation of momentum, asserting that an object cannot simply be stopped by surrounding it with a pressurized medium. The conversation emphasizes the challenges of manipulating the rotation of space debris, suggesting that matching rotation may be more feasible than attempting to halt it entirely.

PREREQUISITES
  • Understanding of conservation of momentum
  • Basic principles of rotational dynamics
  • Familiarity with the physics of vacuum and pressurized environments
  • Knowledge of space debris management techniques
NEXT STEPS
  • Research methods for calculating rotational deceleration in various environments
  • Explore techniques for matching rotation of objects in space
  • Investigate the impact of different shapes on rotational stability
  • Study current technologies for capturing and managing space debris
USEFUL FOR

Aerospace engineers, physicists, and space debris management professionals will benefit from this discussion, particularly those focused on the dynamics of rotating objects in varying environments.

common sense tells me that if an object can remain spinning in the vacuum of space for eternity, than placing that same object within a pressurised environment will cause the object to slow to a stop. is there a way for me to calculate the time in which it would take an object to stop rotating within a pressurised environment? the goal would be to achieve the fastest time in stopping an object from spinning.

By what means? Changing the shape of the object?

thinking along the lines of trash in space. in order to reach out and grab a piece of debris, either it has to stop spinning, or the rotation must be matched. my thought is that rather than 'grabbing' it, surround it and pressurise the space around it so to stop the rotation.

Sorry, but this doesn't make any sense to me. Why would you do it?

That won't work because of conservation of momentum. We don't know your background. Do you understand "because of conservation of momentum" ?
