The article title is misleading, but the research is interesting. Essentially it’s saying that when the rocket self-destructed due to it performing off nominal (as the first test ever of this vehicle) it ionized a large swath of the ionosphere from Mexico to the SE US which can impact the accuracy of GPS for systems that require high precision. The ionosphere reionizes very quickly naturally though so the effects are short lived (hours to maybe a day) and the impact to navigation at least should be small because of how GNSS works with built in corrections for exactly these types of errors. It feels like Nature is stretching a bit with the doom and gloom headline that the authors don’t even point to in the article (though I have not read the paper to be fair).
