The VLM (Veículo Lançador de Microssatélites) is a proposed Brazilian satellite launcher. The project originated as a simplified version of the VLS-1 rocket, using only the core stages.Currently, a version based on the S50 rocket engine is being studied, with the objective of orbiting satellites up to 150 kg in circular orbits ranging from 250 to 700 km. It will be a three-stage rocket, expected to launch the SHEFEX III mission by the German Aerospace Center (DLR) in 2016.
