Gucsik et al (2012b) performed a systematic cathodoluminescence study of the micro-and nanodiamond samples, which were studied at room and liquid nitrogen temperature in order to understand more about the temperature-dependence of the spectral properties of diamond in the planetary nebulae.…”

We have proposed that solar ultraviolet and corpuscular radiations may excite photoluminescence and cathodoluminescence of the solid cometary substance including mineral halos of comets. Main characteristics of such possible luminescence and physical mechanisms of these phenomena have considered. Results of the tentative identification of previously unknown cometary emissions and data of laboratory research of meteorites are presented. We have shown as well that cometary solid substance may demonstrate red luminescence - similar of red luminescence by the circumstellar dust. Some other aspects of the problem have also been considered.

Data-Driven Guidance and Control for Asteroid Landing Based on Real-Time Dynamic Mode Decomposition

et al. 2023

Navigation and control near asteroids are challenging due to high levels of uncertainty, necessitating a high degree of autonomy and safety. To address this challenge, we propose a novel method for leveraging data-driven approaches, which have garnered significant attention in recent years. Traditional data-driven and machine learning techniques have been applied to space exploration problems; however, they often require large amounts of data in advance and are not robust to unknown environments. Hence, they are typically used in auxiliary roles and are not easily adaptable to real-time modeling and control. We propose the use of the theory of dynamic mode decomposition (DMD) and delayed embedding to construct a datadriven real-time guidance and control system for asteroid landings. Our approach employs low-dimensional information obtained from onboard sensors to construct nonlinear dynamics in the vicinity of asteroids. Based on the constructed dynamical model, we propose a guidance control strategy for accurate and reliable spacecraft landing. Our proposed method has the potential to improve guidance and control systems for space exploration by enabling real-time modeling and control with reduced computational cost.INDEX TERMS Data-Driven, landing control, real-time performance, delayed embedding.
