“… Sdunnus et al [2004] have compared the flux as a function of d p in the ISS orbit predicted by three models: ORDEM2000 [ Liou et al , 2002]; MASTER 99 [ Wegener et al , 2002; Sdunnus et al , 2001] and SDPA 2000 [ Nazarenko and Menchikov , 2001]. The minimum size of particles included in these models is 10 μm.…”

“…Nonphysical extrapolations to the nanometer size regime of the ORDEM2000, MASTER 99, and SDPA 2000 models of particle flux for a spacecraft in an ISS orbit [ Sdunnus et al , 2004]. Also shown is the detected flux of the smallest holes (D h < 1 μm in Figure 5) in the filmed MCP.…”

An impactor diameter d p of $15 nm is assumed on the basis of the calculated ballistic limit of a 60 nm aluminum film.…”

[1] Microchannel plates bearing a 60 nm thick aluminum film have been exposed to the external International Space Station (ISS) environment for 756 days. Postretrieval analysis has revealed holes in the aluminum film, which may have resulted from impacts by dust particles as small as a few tens of nanometers in diameter. Such particles have been undetectable by previously flown, much thicker foils. The flux of such particles appears to be consistent with the extrapolation, to this particle size regime, of current models for the near-Earth dust and debris environment and data from previously flown foils.

“…For this reason, some studies are ongoing to improve the model, adding more data points or introducing some physical equations (e.g., the momentum conservation) [28,29]. However, at the moment no better breakup model is available and the NASA model can be considered as a standard as it is the most used in space debris models [30] (Legend, Master, Damage). Moreover, the analytical method proposed here does not rely on a specific breakup model: any alternative model, as for example Impact [31], can be implemented changing only the first block shown in Figure 1, whereas the other blocks would not require any modification.…”

Current debris evolutionary models usually neglect fragments smaller than 10 cm because of the high computational effort they add to the simulation. However, small debris objects can also be dangerous to operational satellites. This work proposes an analytical approach to describe the evolution of a cloud of small fragments generated by a collision in Low Earth Orbit. The proposed approach considers the cloud globally and derives its evolution analytically, in terms of the change in the spatial density under the effect of atmospheric drag. As a result, the analytical approach allows the representation of small fragments and noticeably reduces the computational time under 10% compared to the numerical propagation of all the fragment trajectories.For altitudes above 800 km the relative error compared to the numerical method is lower than 10%. R E = Earth's radius [km]

“…Organization of populations is unique to each model and is somewhat based on available data and chosen analysis techniques. Cursory comparisons between modeling program outputs have been performed over the last decade [1,2]. In-depth studies were postponed partly due to development scheduling.…”
