航天是一项典型的超大规模复杂系统工程，管理和决策贯穿航天工程的每个环节。航天是一个真正产生大数据和迫切需要大数据技术的领域，也是大数据理论与技术能够实实在在找到用武之地和发挥巨大效能的特殊领域。本项目以航天器的安全管理为对象，开展管理与决策导向的航天大数据关联分析与挖掘建模、航天大数据管理与决策知识学习与统计推断、航天大数据全局视图与预测、多源异构大数据管理与决策知识发现、多源异构大数据融合与实时分析，以及航天大数据平台构建超长时序大数据分析关键技术等6项15款内容的研究，建立有显著创新和自主知识产权的航天器在轨运行过程全寿命周期安全管理和故障与灾变决策支持技术，解决航天大数据分析与应用的3个方面关键性技术难题，服务航天器在轨安全管理与决策，为降低航天器故障危害和规避突发灾变风险、保障航天安全提供强有力的技术支撑。

Spaceflight is a typical large scale complex system engineering, management and decision-making run through every all departments of aerospace engineering. Spaceflight is a real field which not only produces big data and urgently need techniques to deal with big data, but also the big data theory and technologies can really find their way and play great performance in these special fields. Aiming at the safe management of spacecrafts in orbits, this project will do further research on fifteen items of techniques, which relate to six different aspects:the management and decision oriented aerospace big data analysis and mining of association space modeling, big data management and decision-making knowledge learning and statistical inference, aerospace big data oriented global view and prediction, multi-source heterogeneous big data management and decision knowledge discovery, multi-source big data fusion and high real-time analysis, construction of aerospace data platform and some key techniques of very long time series data，etc. After the project is accomplished, a series of significant innovation results will be given with independent intellectual property rights,which are helpful for the safety management and decision support of faults/disastrous failures arising at the total life cycle of spacecraft in orbit,three aspects of the key technical problems will be solved for aerospace big data analysis and applications.These research results will service spacecraft safety management and decision-making support, so as to reduce spacecraft fault hazard and avoid the risk of sudden disaster and protect the safety of spacecraft and to provide strong technical support for aeroflight engineering.
