- I would suggest you drop the word orbit. There is no possible orbit
- that can put a satellite continuously over Nevada. None. Period.
-
- The only possibilities are solar sails and maglev devices that sit at
- least several thousand miles up. They would not be in free fall, they
- would be using an energy source to counter the acceleration due to
- Earth's gravity at that altitude.
-
- There may be other engineering solutions, such as active structures
- built from the surface; or perhaps a GSO beanstalk with cables off to
- either side at your latitude and with platforms at the desired
- altitude. None of these is likely to be built any time in the near
- future. Within our lifetimes? Possibly. But not soon.
