Field notes
The guide gives concrete reference examples, including an ISS chase-camera view and Apollo 11’s position on a specified date. It also says time can advance at rates from one second per second to one year per second, and lists 12 calendars. The page describes free-to-research access levels, but the extracted material does not provide their prices or clarify which functions require an account.
