The Modular Common Spacecraft Bus is a fast-development, low-cost, general purpose spacecraft platform. Its modular design is intended to reduce the cost, complexity, and lead time on missions by providing a reliable, well-characterized system that can carry a variety of payloads. According to NASA, "the spacecraft is roughly one tenth the price of a conventional uncrewed mission and could be used to land on the Moon, orbit Earth, or rendezvous with near-Earth objects."
