India's space sector is witnessing a revolution, and Agnikul Cosmos is at the forefront! This Chennai-based startup, founded in 2017, has successfully launched Agnibaan, its sub-orbital test vehicle, powered by the world's first single-piece, 3D-printed rocket engine. This achievement, after several attempts, signifies a major breakthrough in space technology. The 3D-printed engine reduces manufacturing complexity and lead time, paving the way for faster, more affordable rocket assembly. What this means for the future: Reduced Launch Costs: 3D printing can significantly lower production costs compared to traditional manufacturing methods. This translates to cheaper launch services, making space more accessible for organizations and researchers. Faster Turnarounds: 3D printing allows for rapid customization and iteration of engine designs. This can accelerate development cycles and get satellites into orbit quicker. A Booming Private Space Industry: Agnikul's success is...
