The following are statements from Pam Melroy and NASA Administrator Bill Nelson on Thursday’s U.S. Senate confirmation of Melroy as deputy administrator of the National Aeronautics and Space Administration:
“It’s an honor to be confirmed by the Senate to serve as NASA Deputy Administrator, and I am humbled by President Biden and Vice President Harris’ confidence in me,” Melroy said. “I look forward to returning to the NASA family and working with Administrator Nelson to ensure the United States continues to lead in space and beyond – exploring the wonders of the universe, expanding the Earth science research critical to combatting climate change, unlocking scientific discoveries that will change the world as we know it, and inspiring the next generation of discoverers and dreamers.”
“Pam is a pioneer and veteran of NASA, and will be an outstanding leader as we venture farther out to the stars,” said Nelson. “We certainly are lucky to have her on board, and I look forward to leading NASA with her as a team.”

… if electrons can move only in certain orbits, wouldn’t that law be in space scale too.
So!
The point would be:” is that a reason why the Saturn has the rings it has?”… and some other places you have some granulation in the rings…
Yes and no
Orbital dynamics in some ways mimics electron behavior but it is only superficial, if you want to use zero fuel yes you must have a fixed speed and orbit, but unlike electron that must be triggered to change energy levels, macro scale orbits always encounter resistance and degrade because there is no pure vacuum within the galaxy, an no escape from some gravitational field or another so unlike an electron that is happily spinning forever (essentially) in space you need a constant input of energy to maintain a stable long-term orbit. In space every thing is essentially circling the drain just because of the masses and speed involved the time scales are huge
