Solar storm has killed 40 SpaceX satellites! If you want to learn about the harmful side-effects of a solar storm, you should read this. On Friday, a solar storm passed Earth and, in the process, rendered 40 SpaceX satellites dead. SpaceX had launched a total of 49 Starlink satellites on Thursday and were in process to achieve their destined orbits when the solar storm hit. Most of them were not able to achieve the desired orbit, and are now falling back to Earth.
But you don’t need to worry about satellites popping out of the sky while you are enjoying a nice sunshine in your backyard. All these satellites will be consumed by the Earth’s atmosphere upon re-entry. SpaceX assures that there’s no chance of a collision between these satellites and the ones already in orbit. All the debris will burn up in the upper atmosphere of the planet.
The issue came up due to increased drag created by the solar storm in the upper reaches of the Earth’s atmosphere. “These storms cause the atmosphere to warm and atmospheric density at our low deployment altitudes to increase. In fact, onboard GPS suggests the escalation speed and severity of the storm caused atmospheric drag to increase up to 50 percent higher than during previous launches,” says SpaceX.
The SpaceX team also tried to fly the satellites edge-on to minimise the drag as part of the safe mode operations. However, the drag was high enough to precent the satellites from leaving the safe mode and begin is orbit raising manoeuvres. Hence, some have already re-entered the atmosphere while other are in the process to plummet down to Earth.
However, nine of the satellites are safely deployed and will be joining the Starlink service.
“The deorbiting satellites pose zero collision risk
