A powerful geomagnetic storm has doomed 40 Starlink satellites launched by SpaceX last week, the company has announced.
The surge warms the upper atmosphere and increases its atmospheric density such that the drag experienced by satellites in low Earth orbit can be enough to send them tumbling back to Earth. The geomagnetic storm experienced by the satellites came from solar wind kicked out by a January 30 coronal mass ejection – an eruption of the Sun.
This"edge-on" positioning, by decreasing the surface area of the satellite passing through the atmosphere, was an attempt to halt the rapid deceleration of the satellites.
