A batch of 49 Starlink internet satellites were on SpaceX’s latest launch on February 3, and now the company is expecting to lose most of them because they hit a space weather event known as a geomagnetic storm. This event occurs when streams of charged particles, or solar winds, emitted from the sun interact with Earth’s magnetic field. The energized particles can heat up the upper atmosphere, causing it to thicken. (Yes, there is still atmosphere in areas of outer space closest to home. The Earth’s atmosphere fades out over thousands of miles.)
