Safari does not work when you try to do this in JavaScript:
const date = new Date('2022-01-08 17:26:59');
Instead, it requires a 'T' between the date and the time:
const date = new Date('2022-01-08T17:26:59');
Fixed this issue in the moonradar.html and positions.html demos.
We still render the date/time as normal, with the space,
but parse it by replacing the space with 'T'.
Thanks to @ebraminio for reporting this!
Added a web page that calculates the round trip time
of a radar pulse from an observer at a given location on
the surface of the Earth to bounce from the Moon and return
back to that observer.
