Keep in mind that it’s not just the $10-$15 million estimated launch cost
that is an obstacle. A molniya orbit passes through the GPS belt altitude
and potentially through both the protected LEO and GEO altitudes depending
on perigee/apogee of the orbit. A future HEO will need an orbital debris
mitigation plan acceptable to the government the satellite is licensed by.
