Geomagnetic Storm Dooms 40 (of 49 Just Launched) Starlink Internet Satellites

Excerpt:
"Elon Musk's satellite internet service Starlink experienced a devastating space-weather impact last Friday when a geomagnetic storm forced "dozens" of newly launched low Earth orbit (LEO) satellites into "safe-mode" where they experienced "deorbiting" and will or already have crashed back to Earth, according to a SpaceX blog post.

"Unfortunately, the satellites deployed on Thursday were significantly impacted by a geomagnetic storm on Friday. 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. The Starlink team commanded the satellites into a safe-mode where they would fly edge-on (like a sheet of paper) to minimize drag—to effectively "take cover from the storm"—and continued to work closely with the Space Force's 18th Space Control Squadron and LeoLabs to provide updates on the satellites based on ground radars.

Preliminary analysis show the increased drag at the low altitudes prevented the satellites from leaving safe-mode to begin orbit raising maneuvers, and up to 40 of the satellites will reenter or already have reentered the Earth's atmosphere," the blog post said.

SpaceX said the "deorbiting satellites pose zero collision risk" with other satellites and are designed to burn up in the atmosphere upon "reentry" to mitigate satellite parts from striking objects on the ground. "
