## Editorial
Dragonfly Bus is a 150-200 kg class satellite bus for high-power Earth-observation payloads, including synthetic aperture radar payloads.[^satcatalog-dragonfly-bus][^spaceinafrica-dragonfly-products]

SatCatalog gives a 150 kg dry mass for the bus, while Dragonfly product-launch coverage describes the platform as a 200 kg class bus.[^satcatalog-dragonfly-bus][^spaceinafrica-dragonfly-products] The bus accommodates payloads up to 250 kg in a 1000 x 1000 x 1000+ mm envelope, with solar-array peak power up to 1130 W, 710 W orbit-average bus power, and up to 2400 Wh of energy storage.[^satcatalog-dragonfly-bus] Payload power is described as 3.5 kW peak, while orbit-average payload power is given as 630 W in the launch coverage and 710 W in the SatCatalog specification.[^satnews-dragonfly-products][^satcatalog-dragonfly-bus]

The platform specification includes X-band downlink at 1 Gbps, pointing stability below 0.002 deg/sec, pointing accuracy below 0.02 deg, slew rate up to 2 deg/sec, xenon electric propulsion for orbit maintenance, full component redundancy, and an eight-year design life.[^satcatalog-dragonfly-bus]
