The Plasmasphere

Most of the mass of particles in server sky orbits is cold (<1eV) plasma, in the upper fringes of the atmosphere. The total mass of these particles is small. This plot shows density versus distance

orbit	Radius	L_min	L_max	Dens_min	Dens_max	Volume	Mass
m288	12789 km	1.93	2.14	4500/cm³	7000/cm³	1.8e12 km³	17000 kg
m360	14441 km	2.19	2.42	2500/cm³	4000/cm³	2.6e12 km³	14000 kg
m480	16756 km	2.55	2.79	1200/cm³	2500/cm³	3.5e12 km³	11000 kg

A few thousand tons of thinsats will vastly increase the number of coulomb scattering centers.
