Origins,worlds,and life:a decadal strategy for planetary science and astrobiology 2023-2032,the 3rd planetary decadal in 21st century to guide the solar system exploration in the coming 10 years (hereinafter referred to briefly as Decadal 2023),covers a broad range of recommendations such as science missions,research and analysis,and technologies.The article focuses on its three scientific themes,the recommended science program with big,medium and small missions,the deep space probes under development adopted by the previous decadal,and the cross-discipline missions which aim to achieve groundbreaking discovery in search for life elsewhere.Moreover,the Decadal 2023 includes for the first time the elements of planetary defense and state of profession,the latter of which interprets space science's social values.Though the planetary science just started lately in China,it has entered a rapid development phase benefiting from lunar and planetary explorations of China.The article aims to inspire future planetary progress in China through lessons learned from the American planetary decadal practices,e.g.,implementing science-driven missions with cutting-edge technology,emphasizing research and analysis,and investing new instrumentation development.
