即将建成的平方公里阵列（SKA）射电望远镜将成为最大的天文观测设施，有望给自然科学的主要领域带来革命性的变化。这些革命性的变化帮助我们回答宇宙起源、生命、宇宙磁场、引力本质等基本问题，并帮助我们寻找地外文明[1]。 SKA前所未有的强大特点是极高的灵敏度、宽视场、超快的巡天速度以及超高的时间、空间、频率分辨率，这确保了SKA在未来射电天文学领域的领先地位；这将伴随着大量艾字节（EB）级别的观测数据。 SKA级数据的传输、存储、读取、写入、计算、管理和归档以及SKA科学产品的发布对信息通信技术（ICT）领域提出了严峻的挑战。中国SKA科学团队将与信息、通信和计算机行业共同应对SKA大数据带来的挑战，这不仅将推动重大原创性科学发现，还将所获得的技术成果应用于拉动国民经济。
The upcoming Square Kilometre Array (SKA) radio telescope will become the largest astronomical observation facility, and is expected to introduce revolutionary changes in major fields of natural sciences. These revolutionary changes help us to answer the fundamental questions related to the origins of the universe, life, cosmic magnetic field, the nature of gravity, and to search for extraterrestrial civilizations [1]. The unprecedented power of the SKA is characterized by an extremely high sensitivity, wide field of view, ultra-fast survey speed, and ultra-high time, space, frequency resolutions, which ensures that SKA will have a leading position in radio astronomy in future; this will be accompanied by a vast amount of observational data at exabyte (EB) level. The transportation, storage, reading, writing, computation, curation, and archiving of the SKA-level data and the release of SKA science products are posing serious challenges to the field of information communication technology (ICT). The China SKA science team will work together with the information, communication and computer industries to tackle the challenges associated with the SKA big data, which will not only promote major original scientific discoveries, but also apply the obtained technological achievements for stimulating the national economy.
