Global Proposal Competition on Near-Earth Asteroid Defense and Queqiao System was released at the First International Deep Space Exploration Conference (Tiandu Forum) in April 2023. The contest set up two theme tracks of the Near-Earth Asteroid Defense Space Disposal Solution and Queqiao Communication, Navigation, and Remote Sensing system. Participants are not restricted by country, region, specialty, or age, and individuals from all walks of life are encouraged to apply.

Near-Earth Asteroids (NEAs) impacting on Earth has been a great hazard for long-term development of human. To strengthen our response to such risk, a plan has been devised to formulate NEA defense mission from 2025 to 2035, following the development path of “hard impact, soft propulsion, and smart control”, the objects of which include selecting disposal targets for each phase, diversifying disposal techniques, and enhancing overall response capabilities. Participants can choose a specific theme track based on their professional expertise and career orientation. While detailing specific design aspects related to their chosen theme track, participants must also consider other requirements to ensure the overall integrity of the NEA Defense Space Disposal Solution.

Integrating communication, navigation, and remote sensing functions into one，Queqiao serves as a crucial component of the Earth-Moon space infrastructure. This system can interconnect and integrate Earth-based control communication systems, lunar-based control communication navigation systems, and Earth-Moon space communication systems. It facilitates interconnection, communication, and interoperability within the system, between systems, and across missions. As human space exploration activities become more frequent, the exploration of space has extended from Earth-Moon space to Earth-Mars space and even the outskirts of the solar system, so the design of the Queqiao Communication, Navigation, and Remote Sensing Constellation System should not be limited to Earth-Moon space. It can be expanded to the deeper reaches of space to support the construction of an interplanetary internet. Participants can choose a specific theme track based on their professional expertise and career orientation. While detailing specific design aspects related to their chosen theme track, participants must also consider other requirements to ensure the overall integrity of the Queqiao Communication, Navigation, and Remote Sensing Constellation System proposal.
