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.

Hi Greg, That is hard to say exactly for sure as it actually has not been done yet. Maybe somebody else out there knows? I do know AO-10/13 was around 140kg at launch with fuel and is 90kg without fuel. So it would be significantly less as the fuel does weigh a lot (50kg?). Also a quick search shows that a 400N motor weights around 9.5 pounds, so minus that.Unfortunately that launch opportunity for the direct launch to a Molniya type orbit was scrapped. Hopefully AMSAT find some sort of a affordable launch opportunity for it here soon in the up coming years. It is difficult enough now a days just to get a 1-2kg cubesat into LEO unfortunately.
