Potential Perturbation of the Ionosphere by Megaconstellations and Corresponding Artificial Re-entry Plasma Dust [PDF]
arXiv, 2023 500,000 to 1 million satellites are expected in the next decades, primarily to build internet constellations called megaconstellations. These megaconstellations are disposable and will constantly re-enter and be replaced, hence creating a layer of conductive particulate.

Spaceflight from Super-Earths is difficult [PDF]
International Journal of Astrobiology 18 (2019) 393-395, 2018 Many rocky exoplanets are heavier and larger than the Earth, and have higher surface gravity. This makes space-flight on these worlds very challenging, because the required fuel mass for a given payload is an exponential function of planetary surface gravity.
