Libertad 1 (English: Freedom 1) is a single CubeSat built by the Space Program of the Sergio Arboleda University in Colombia. It was launched aboard a Dnepr rocket on April 17, 2007 from the Baikonur Cosmodrome, Kazakhstan and became the first Colombian satellite to orbit the Earth. It used a telemetric payload to keep it in communication with the University. It was expected to have a 50-day lifespan, however news reports two years after it was launched stated the satellite was still working and sending information, passing over Colombia twice a day.
