One Sidereal Day Construction orbit and associated plumes

A 1 sidereal day construction orbit with a perigee radius of 8378 km ( 6378 + 2000 ) and an apogee radius of 75950 km ( 2*42164 - 8378 ) has an apogee of 11.9 Re. Retrograde plumes for apogee orbit insertion will all orbit above the bow shock (and be exposed to the proton flux of the solar wind) many times per year. Two relevant related orbits will be a launch orbit from a perigee radius of 6458 km, and a HEEO to GEO/Laplace transfer orbit with a perigee radius of 42164 km (Ignoring J₂ gravitational effects):
