### Long-Term Universal Efforts  
Planning, developing, deploying, maintaining, and upgrading such a huge SCADN framework would require significant resources and efforts across many various entities. There will be expectations of critical collaborations among space agencies (e.g., NASA, ESA), governments, intergovernmental organizations (e.g., EU, ITU), research facilities, technical and professional associations (e.g., IEEE, AIAA), and technological corporations (e.g., SpaceX, Blue Origin), etc.  
Furthermore, the legislation of related laws and standards is another critical success factor. The famous astronomer and planetary scientist Dr. [PERSON] expressed concern about deflection technology in his book _Pale Blue Dot_[173] where he noted that any method capable of deflecting space objects away from Earth could also be abused to divert non-threatening bodies toward the planet. Therefore, rigorous legislation and implementation are of the highest priority and importance during the top-down design of the proof-of-concept (PoC). For example, efficient public supervision and timely disclosure may help improve the eventual success of the SCADN framework. Also, developing and widely adopting advanced AI algorithms can decrease the unauthorized manipulation or mistakes of manual operations and enhance the cyber-security and overall performance of the SCADN framework. The authorization of upgrading the framework and core AI algorithms may require the highest-level granting from multiple entities to best serve the common interest of all humankind.  
In addition, several related international treaties should be taken into account when planning and developing the SCADN framework. The first is the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty (NPT). It aims at preventing the spread of nuclear weapons and weapons technology to promote cooperation in using nuclear energy peacefully, with a further target of achieving nuclear disarmament, including general and complete disarmament [174]. The second one is The Outer Space Treaty (OST), formally the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and other celestial bodies. The OST is a multilateral treaty that forms the basis of international space law. In particular, it has included several key provisions such as prohibiting nuclear weapons in space and limiting the use of the Moon and all other celestial bodies to peaceful purposes [175]. Consequently, there is a necessity for considerable investigation of the asteroid/comet mitigation technologies under both NPT and OST. The SCADN framework is likely to comply with these treaties since early detection can enable the use of slow and steady mitigation technologies.  
Moreover, fully deploying the SCADN framework may take significant time. Dividing the construction into several stages is thus reasonable and also feasible. For example, Phase I of the SCADN framework can target the coverage of the area reaching Jupiter. It is also noteworthy that several factors need to be considered as they can interrupt the progress to some extent. For instance, the global supply chain can be disrupted during emergencies such as wars and pandemics [176].
