Historically, the majority of the tracking of objects in Earth orbit has been conducted by “remote” sensors, based on the…

A potentially under-explored aspect of SSA is the extent to which satellite launch activities can have an effect on the…
An active Sun causes the atmosphere to expand, increasing the drag on all objects, and causing the ones in the lowest orbits to re-enter the Earth’s atmosphere, thereby decreasing the total debris population. But what can we expect if the Sun enters a "grand minimum"?
One of the principal challenges associated with predicting the future debris population is modelling hypervelocity collisions accurately. We assume that higher closing velocities result in more fragments with smaller sizes; but how many more?
