Theme Track

1）Global proposal competition for Near-Earth Asteroid Defense Space Disposal Solution

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.

Theme track I: Call for the name and logo of China's first Near-Earth Asteroid defense mission

China's first NEA defense mission is scheduled for the implementation of a kinetic impact demonstration and validation experiment around 2030. Participants are tasked with designing the mission's name and logo.

Theme track II: Call for the general proposal of the first mission

China's first NEA defense mission has preliminarily identified 2015 XF261 as the target. Participants are required to submit the back-up proposal and model of China’s first NEA defense mission, including but not limited to target selection, orbit design, overall indicator design, ground monitoring, and support plans, which could be verified by the combination of impact and evaluation on-orbit, and synchronously measure the characteristics of target and evaluate the impact effect.

Theme track III: Call for subsequent mission planning

To meet the development needs of the NEA defense system, participants are tasked with designing 3-5 NEA defense missions for the mid-to-long-term planning period of 2025-2035. The design should include but not limited to technical roadmap, a comparison of disposal methods, optimized orbit design, simulation verification, and effectiveness assessment methods, aligned with the NEA defense mission’s objective of impact accurately’, ‘push-off distinctly’ and ‘control exquisitely’.

2）Global proposal competition for Queqiao Communication, Navigation and Remote Sensing system

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.

Theme Track I: Call for the planning and design of single mission

The establishment of the complete configuration of the Queqiao Communication, Navigation, and Remote Sensing Constellation System requires multiple missions. Considering the current utilization of Earth-Moon space, participants are required to provide a detailed design for a specific mission within the overall system. They should explain the importance or uniqueness of this particular mission in the overall plan (e.g., first mission, final mission, accomplishing multiple satellite layouts in one mission, etc.). The submission should include details such as the mission objectives, the number of satellites to be launched, orbit design, spatial layout, network topology, functional architecture, and relevant models.

Theme track II: Call for the planning and design of overall mission

Based on the current international space situation, participants are tasked with designing the overall configuration of the Queqiao Communication, Navigation, and Remote Sensing Constellation System. They should provide an overall plan, including constellation spatial layout, network topology, and functional architecture, and describe its supporting capabilities for deep space exploration missions like lunar and Martian probes. Considering engineering capabilities and costs, participants should plan 3-5 Queqiao Communication, Navigation, and Remote Sensing satellite missions. They need to outline the process for each mission, including the cycle, mission objectives, orbit design, and form a comprehensive planning and design proposal.
