Today, astronomy not only plays a vital role as a forefront discipline in natural science — broadening human understanding of the cosmos — but also contributes significantly to the cultivation of highly skilled professionals in advanced science and technology. With the establishment of the Korea Aerospace Administration in 2024, it is expected that awareness of the importance of astronomy in promoting scientific development and training next-generation experts in high-tech fields will grow even further in Korea. At this critical juncture, the Strategic Planning Committee of the Korean Astronomical Society has recently identified the astronomical research challenges that Korea’s astronomy community should pursue over the next ten years, as well as the infrastructure needed to support these endeavors. This talk will introduce the preliminary result of this decadal survey of KAS. Among the grand astronomical challenge, KAS aims to tackle two key scientific themes in the next decade: (1) understanding the past and future of the universe, and (2) uncovering the origins of humanity from a cosmic perspective. We have also identified five major types of facilities/activities to enable us to pursue the key scientific themes: (1) new generation large-scale ground based observatories; (2) observational facilities with new messengers other than light; (3) creative, korean-led projects; (4) space-based observatories; and (5) data archive and high performance computing center. These infrastructure development road map recommendations will be also presented, along with the remaining tasks of the Strategic Planning Committee to prioritize the infrastructures.
