Estimated fractional mass ablation of meteoroids in dependence of the meteoroid mass. Values are given for each mass decade. For details on the derivation, see the text. Note that all of those values are rough estimates.
Source publication
Every year, more and more objects are sent to space. While staying in orbit at high
altitudes, objects at low altitudes reenter the atmosphere, mostly disintegrating and adding material to the upper atmosphere. The increasing number of countries with space programs, advancing commercialization, and ambitious satellite constellation projects raise...

Context 1
... mass dependent fraction of the three different ablation products is displayed in Figure 4, based on the results from the previous two sections. For nearly every meteoroid mass, the material is injected into the atmosphere either in atomic or aerosol form. ...
Context 2
... strong difference in temperature and the different materials imply different ratios of the atomic and aerosol ablation for meteoroids/fireballs and anthropogenic material. In need of better data, we assume a higher aerosol fraction (75 %) for the anthropogenic material while that one of meteoroids is only about 30 % (compare with Figure 4). This is due to higher temperatures causing transition into the gas and/or plasma phase. ...

The massive mega constellation of satellites will have a significant impact on global space safety. With Starlink as an example, this paper is aimed at assessing the risk of in-orbit collision, analyzing the probability of collision in orbit in its natural operating state, and forecasting the probability of secondary collision between the collision...
