 Two Surrey Satellite Technology satellites were launched, the 100 kg Carbonite-2 Earth Observation technology demonstrator and the 168 kg Telesat LEO Phase 1 communications satellite.Four SpaceBEE sub-CubeSats were launched to test "2-way satellite communications and data relay", probably for the Silicon Valley company Swarm Technologies.However the U.S. Federal Communications Commission (FCC) had denied regulatory approval for Swarm Technologies 10 cm × 10 cm × 2.8 cm BEE satellites as they were too small to be reliably tracked by the United States Space Surveillance Network, so may become an impact hazard to other satellites.
