"mbps" is a meaningless abbreviation. You need to consistently and correctly use capital letters when communicating technical terms. You cannot "e e cummings" your way into effective writing.
500 megabits per second works out to 5.4 terabytes per day. No idea where you get 1.5, unless you were thinking of 500Mb/hour!
60 × 60 × 24 × 500 × 1000000 ÷ 8
my brain is not what it used to be due to long-covid so it's very possible I made a mistake
but 500 megabits per second to me is 500mbps?
ie. my cablemodem is 100mbps which is 100 megabits per second?
and that would [make Roman] 5.4 Terrabytes aka 5.4TB per day
but the transmitter is not at full speed full power 24/7
so it is 1.5TB per day in documentation that I do not have handy but vaguely remember
to repeat the more amazing part is that is from a MILLION MILES away, wow
(JWST "only" does 23mbps, 23 megabits per second)
