NASA’s CHAMPS initiative harnesses solar-electric propulsion, enabling cost-effective, scientifically rich Mars exploration with small satellite platforms.

NASA’s Mars Exploration and Propulsion Advances

Revolutionizing Small Spacecraft Propulsion for Martian Missions

Through its “Moon to Mars” program, NASA plans to send the first crewed missions to Mars by the end of the next decade. This ambitious undertaking necessitates the implementation of advanced technologies through various programs. Among the critical focus areas are propulsion technologies, which aim to minimize transit times to Mars, significantly reducing astronauts’ exposure to microgravity and cosmic radiation. Additional technologies under investigation encompass methods for waste management, water extraction and recycling, crew health and safety, and achieving self-sufficiency in resources.

A Technology Gap in Space Propulsion

NASA is also exploring essential technologies that would facilitate cost-effective exploratory missions to Mars and beyond. Among these technologies, sub-kilowatt electric propulsion systems stand out as a primary focus for small spacecraft (those weighing 500 kg or less). A…
