I did a deeper investigation to get to the supply of the reported loss on quite a few Starlink satellites launched by Elon Musk. As reported on 3 February 2022, SpaceX launched 49 Starlink satellites, 38 of which unexpectedly deorbited. The deorbiting of the satellites was blamed on area climate. A little bit of clarification on House climate:
House Climate Prediction Middle, Nationwide Oceanic and Atmospheric Administration
House Climate describes the variations within the area surroundings between the solar and Earth. Particularly. House Climate describes the phenomena impacting techniques and applied sciences in orbit and on Earth. House climate can happen anyplace from the floor of the solar to the floor of Earth. As an area climate storm leaves the solar, it passes by way of the corona and into the photo voltaic wind. When it reaches Earth, it energizes Earth’s magnetosphere and accelerates electrons and protons right down to Earth’s magnetic discipline strains the place they collide with the ambiance and ionosphere, notably at excessive latitudes. Every element of area climate impacts a special know-how. An outline of a few of the area climate impacts will be discovered at House Climate Impacts.
What the examine (The Lack of Starlink Satellites) determines is “what contributed” to the deorbiting of the satellites. The authors supplied a “plan- language” willpower of findings which I’ve added beneath. Extra element in a technical method will be discovered utilizing the hyperlink within the title.

Plain Language Abstract
Human society is changing into more and more depending on satellites at Low Earth Orbit (LEO) which cater to Earth observations, telecommunications, navigation and protection wants. The impression of area climate–altering environmental situations in area ruled by the Solar–at Low Earth Orbits is barely starting to be appreciated. The lack of an unprecedented variety of Starlink satellites after their launch on 3 February 2022, which was attributed to area climate, is a living proof. Surprisingly, photo voltaic magnetic storms and area climate situations across the time of the launch of the Starlink satellites have been fairly modest, making it difficult to determine bodily causality. Right here we make the most of a multipronged method primarily based on observations of photo voltaic magnetic storms, close to‐Earth environmental situations and novel laptop simulations to determine causality between the prevailing area environmental situations at LEO and the lack of the satellites. Our complete evaluation reveals that the lack of the satellites was resulting from a mixture of things together with prevalent area climate situations, an insertion at a comparatively excessive‐density LEO and probably enhanced drag resulting from orientation modifications of the satellites accentuated by a comparatively excessive drag to inertia ratio
