A SpaceX Falcon 9v1.2FT Block 5 rocket successfully launched the communications satellite Galaxy 37 (aka Horizons-4) communications satellite at 0500 GMT on 3 August 2023. The launch took place from Cape Canaveral, Florida, USA, using the SpaceX-leased SLC-40 pad. The launch put the satellite into a geosynchronous transfer orbit from where the satellite will raise itself to its fully GEO (Geostationary Earth Orbit) operational position over 127 degrees West. The reusable stage B1077, on its sixth flight, successfully landed down range in the Atlantic on the drone ship Just Read the Instructions.
Built by Maxar using its 1300 bus design, the C-band/Ku-band Galaxy 27/Horizons-4 satellite is owned by the new joint venture company Horizons-4 Satellite LLC, a joint enterprise between Intelsat and JSAT International Inc., a subsidiary of SKY Perfect JSAT.
