  This article is a second analysis step from the descriptive arXiv:2001.10952
preprint. This work is aimed to arise awareness to the scientific astronomical
community about the negative impact of satellites' mega-constellations and put
in place an approximated estimations about loss of scientific contents expected
for ground based astronomical observations when about 50,000 satellites will be
displaced in LEO orbit. The first analysis regards the impact on professional
astronomical images in optical windows. Then the study is expanded to other
wavelengths and astronomical ground based facilities (radio and higher
energies) to better understand which kind of effects are expected. Authors also
try to perform a quantitative economic estimation related to the loss of value
for public finances committed to the ground based astronomical facilities armed
by satellites' constellations. These evaluations are intended for general
purposes, can be improved and better estimated, but in this first phase they
could be useful as evidentiary material to quantify the damage in subsequent
legal actions against further satellites deployments.
