A high data rate distribution network for low-earth orbit (LEO) satellite constellations is described. The high data rate distribution network includes multiple LEO constellations, each constellation including a number of LEO spacecraft orbiting in a LEO plane that are all connected together by by-directional free space optical links. The distribution network further includes geostationary earth orbit (GEO) spacecraft in communication with a number of ground gateways. The GEO spacecraft can receive forward communication traffic including radio-frequency (RF) and/or optical data streams uplinked from the ground gateways and can convert the received forward communication traffic into a forward aggregated traffic. The GEO spacecraft can further optically downlink the forward aggregated traffic to LEO spacecraft in a LEO constellation that is in line of sight of the GEO spacecraft. The forward aggregated traffic is then disaggregated among and received by the LEO spacecraft in the LEO constellation. Return communication traffic from each LEO spacecraft can also be aggregated into a return aggregated traffic from the LEO constellation. The return aggregated traffic is optically uplinked to a GEO spacecraft by a LEO spacecraft of the LEO constellation that is in line of sight of the GEO spacecraft. The GEO spacecraft converts the received return aggregate traffic into multiple RF and/or optical data streams that are down linked to a number of ground gateways.
