“…Microgravity and sparse media properties are involved in deep space, this posed strict constraints to ensure safe landing. Zhao et al [150] developed as asteroid landing mechanism with three legs and damping mechanisms with the end-effector platform. It allowed a stable landing with the maximized landing velocity on a slope up to 30 degree.…”

This paper aims to present a comprehensive survey on information integration (II) in space informatics. With an ever-increasing scale and dynamics of complex space systems, II has become essential in dealing with the complexity, changes, dynamics, and uncertainties of space systems. The applications of space II (SII) require addressing some distinctive functional requirements (FRs) of heterogeneity, networking, communication, security, latency, and resilience; while limited works are available to examine recent advances of SII thoroughly. This survey helps to gain the understanding of the state of the art of SII in sense that (1) technical drivers for SII are discussed and classified; (2) existing works in space system development are analyzed in terms of their contributions to space economy, divisions, activities, and missions; (3) enabling space information technologies are explored at aspects of sensing, communication, networking, data analysis, and system integration; (4) the importance of first-time right (FTR) for implementation of a space system is emphasized, the limitations of digital twin (DT-I) as technological enablers are discussed, and a concept digital-triad (DT-II) is introduced as an information platform to overcome these limitations with a list of fundamental design principles; (5) the research challenges and opportunities are discussed to promote SII and advance space informatics in future.INDEX TERMS Information integration (II), space informatics, digital triad (DT-II), internet of digital-triad things (IoDTT), first-time right (FTR), space information integration (SII).

Landing mechanism tends to rebound and turn over, and the stability time is long when landing on the small celestial body. Its landing performance in different conditions is necessary to be evaluated to guide the landing. Here, landing performance evaluation is realized by simulation. Key factors affecting the landing performance including cardan element damping, foot anchors, retro-rocket thrust, landing slope angle, and landing attitude are analyzed. A microgravity platform is built to test the landing mechanism, and the consistency between the simulation and the experiment is compared. On the basis of simulation and experiment, some landing suggestions are proposed to improve the landing performance.
