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.[2][3]

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. If confirmed the FCC may take regulatory action over these satellites.[4][5]
