Launch and failureThe SCD-2A was launched into space on November 2, 1997, by means of a VLS-1 rocket from the Alcântara Launch Center in state of Maranhão, Brazil. It had a mass of 115 kilograms.[2] However, the satellite was lost due to an ignition failure in one of the first-stage thrusters during the first few seconds of flight, requiring the activation of the vehicle's self-destruct command.
