Development Status and Prospects of Near Space Observatories
Unlike ground-based observatories and space-based observatories,the Near Space Balloon Observatory is a unique type of observatory located in near space,mainly relying on high-altitude scien-tific balloon platforms.Throughout the last century,countries such as China and the United States have invested significant effort in promoting the development of high-altitude scientific balloon technology,re-sulting in the establishment of a comprehensive and advanced scientific balloon system,facilitating a wide range of balloon-borne scientific activities,which have facilitated the maturity of near-space obser-vatories.It has the advantages and potential of low distribution and usage costs,short preparation cy-cles,large payload capacity,recyclability for multiple uses,and more flight opportunities.The develop-ment of near space observatories,utilizing high-altitude scientific balloons,has now entered the practical stage.In terms of specific technical research,the focus has shifted from basic application technology to the development of multi-purpose,multifunctional platform structures with high reliability,stability,and precision control.With the ongoing advancements in two key technologies,namely long endurance flight and high-precision pointing,the potential of near-space balloon observatories is being increasingly ex-plored.As early validation platforms for advanced instruments and innovative ideas in space science and astronomy observations,it can effectively enhance the success rate of space-based observatory observa-tion tasks and accelerate the development lifecycle of space-based observatories.As a platform for nur-turing space science talents,it can also cultivate more leading experts and strengthen the research team.This article takes the opening of China's fifth Antarctic Station,the Qinling Station,as an opportunity to suggest timely conducting high-altitude scientific balloon flight tests at the Qinling Station in Antarc-tica,further promoting the astronomical observation of Antarctica by China's near space observatory,and contributing greater strength.
