Ground-based optical observations of the orbital debris environment
Space debris encompasses both natural meteoroid and artificial (human-made) orbital debris. Meteoroids are in orbit about the sun, while most artificial debris is in orbit about the Earth (hence the term “orbital” debris). Orbital debris is the term for any object in Earth orbit that no longer serves a useful function. These objects include non-operational spacecraft, derelict launch vehicle stages, mission-related debris, and fragmentation debris. NASA - Orbital Debris Management and Risk Mitigation

Cosmos 1867 (SATCAT: 18187) non-operational spacecraft orbital debris overpass. Observation date 21.04.2023. Satellite overpass direction from northwest to southeast. Cosmos 1867 was involved in extended fragmentation event from March 21 to April 4, 2014.
H-2A R/B Rocket Body (SATCAT: 28932). Observation date 21.04.2023. Overpass direction from southeast to northwest through hazy atmosphere. Small camera vibrations can be seen on stars.
SL-8 R/B Rocket Body (SATCAT: 8459). Observation date 21.04.2023. Overpass direction from south to northeast. Gray-level co-occurrence matrices texture analysis was applied for track enhancement. Images by order GLCM Mean, Color-infrared, GLCM Variance and Infrared image.
