Brazilian Flight Termination Stops InnoSpace SEBIT Test at Alcântara

Overview

• The SEBIT suborbital test vehicle launched from the Centro de Lançamento de Alcântara was terminated after a trajectory deviation during the flight on Wednesday, Aug. 19, and fell into a designated maritime safety zone without reported injuries.
• Brazil’s Air Force activated the flight-termination system to end the mission about 35 seconds after liftoff, following safety rules that guard populated areas and launch infrastructure.
• InnoSpace says the rocket lifted normally and that telemetry and propulsion, navigation and launch-platform data were recorded and are now under analysis to identify what caused the deviation.
• SEBIT is a single-stage hybrid-propulsion test rocket built to reach roughly 50–100 km and validate systems before orbital launches; this was the first operation at Alcântara since the Dec. 22, 2025 HANBIT-Nano accident.
• The aborted test was flown under a contract with ALADA that marks the agency’s first commercial use of Alcântara, and InnoSpace still plans a HANBIT-Nano orbital attempt in November that remains conditional on technical, regulatory and safety clearances.
