BULL\u0026#39;s HORN device offers a passive solution: a deployable membrane that uses atmospheric drag to accelerate deorbit without propellant. Under a new contract with EnduroSat, HORN will be mounted on a 16U satellite and launched on SpaceX\u0026#39;s Transporter-22 in 2027. The on-orbit demonstration will verify performance in actual space conditions. EnduroSat has experience with over 100 satellites, adding credibility. For BULL, this expands HORN\u0026#39;s application from rockets to satellites, the main source of future debris. Success would make HORN a certified option in EnduroSat\u0026#39;s supply chain.\u003c/p\u003e","blueskyPost":"BULL and EnduroSat will test the HORN deorbit device on a 16U satellite launching on SpaceX's Transporter-22 in 2027.
