“…Conversely, artificial materials make up a much wider range of material types including paints, metals, photovoltaic cells, multilayer insulation, and more. Not many studies have been dedicated to the foundation of a comprehensive database of spectra of these artificial materials, but some relevant studies have focused on polyethylene terephthalate (or PET) materials, solar cell material, solar cell cover glass, aluminum, copper, and thermal control paints measured with various degrees of space-aging effects in a simulated GEO environment (Plis et al 2020(Plis et al , 2021Reyes et al 2021;Shah et al 2023). The lack of a unified spectral database along with the increased number of potential material combinations and appropriately estimated alteration effects to consider makes comparisons of artificial materials challenging (Bengtson et al 2022).…”

Since the dawn of the Space Age, hundreds of payloads have been launched into heliocentric space. As near-Earth object (NEO) surveys search deeper for small asteroids, more artificial objects in heliocentric orbits are being discovered. We now face a challenge to identify the true nature of these objects and avoid contaminating the NEO catalog. Here, we present the methods used to characterize one such object. 2020 SO was discovered by the Pan-STARRS1 survey on 2020 September 17. Originally classified as a NEO, the object’s artificial nature became evident due to its low velocity relative to Earth and solar radiation pressure affecting its orbit about the Sun. Based on a backward propagation of its orbit, 2020 SO is thought to be a Centaur rocket body (R/B) from the launch of the Surveyor 2 mission to the Moon. We characterized 2020 SO using a range of ground-based optical and near-infrared telescopes to constrain its true nature. We find that its reflectance spectrum is consistent with that of other Centaur R/B launched during a similar time frame, and we identify 1.4, 1.7, and 2.3 μm absorption bands consistent with polyvinyl fluoride used on the aft bulkhead radiation shield exterior of Centaur-D R/B at the time.

“…Reflectance spectroscopy is a powerful characterization tool that helps with the identification of micrometeoroid and orbital debris material (collectively referred to by space agencies as MMOD -Micrometeoroid and orbital debris), especially in the research related to asteroids since the 1970s. In the 1990s, its application expanded to the characterization of materials for orbiting spacecraft [4,13,14]. Groundbased spectral measurements are valuable references that assist remote optical observations in analyzing the composition of space debris material, object position and orbital motion.…”

One of the main tasks of the situational awareness system in near-Earth space is to determine the type and class of observed objects by analyzing its reflection spectra. This paper proposes a methodology and interpretation of the spectral observational data of geostationary orbit satellites obtained at the Tian Shan Astronomical Observatory (Kazakhstan) from June-December 2021. 8 geostationary objects, the type and design features of which are known were selected as observation targets. The selected satellites are stable (no fast rotation of these objects was detected) and have large reflecting surface areas. An analysis of the obtained reflection spectra shows the dependence on the phase angle of the object. The studies carried out are especially relevant for objects in high orbits, where the only currently available methods of detection and study are ground-based optical photometry and spectroscopy using meter-class telescopes.

Once the dense plasma covers the charge-discharge sensitive area of solar cells, the ensuing electric fields can form an instantaneous conductive channel to cause arc or electrostatic discharges (ESD) that may disrupt the power generation, transmission, and distribution [7,8]. Additionally, the highvelocity impact of space debris can trigger a plasma discharge effect on solar arrays [9,10].…”

Modeling and Analysis of Non-Linear Phenomena of Satellite Power System in Space Environment and Hazard-Risk Evaluations

With the aim to solve the problem of the non-linear phenomenon of the satellite power system under the influence of the space environment factors, which threatens the stability of the power system, in this paper, the abnormal charging and discharging of solar arrays and solar array drive assembly (SADA) induced by the space plasma environment and accidental events, such as debris impact, and the non-linear behaviors of the solar array and load during the Earth eclipse are modeled and analyzed. On this basis, the hazard risk evaluations of the above non-linear phenomena are carried out, and the weak links of the satellite power system in the space environment are identified. The results show that the unexpected energy of the solar array will increase the current stress and power loss of the power device, resulting in S3R over-regulation. An SADA arc fault will reduce the power supply capacity of the solar array, damage the shunt regulator, and affect the quality of the bus. The non-linear behavior of the solar array and load during the Earth eclipse may damage the battery charge and discharge regulator, seriously affecting the stability of the power system.
