| How NASA spots potentially catastrophic geomagnetic storms before they strike A recent batch of SpaceX’s Starlink internet-beaming cubesats met with tragedy on February 3rd when a 49-member cohort of the newly-launched satellites encountered a strong geomagnetic storm in orbit. “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,” SpaceX wrote in a blog update last Wednesday. “The Starlink team commanded the satellites into a safe-mode where they would fly edge-on (like a sheet of paper) to minimize drag.” Unfortunately, 40 of the satellites never came out of safe mode and, as of Wednesday’s announcement, are expected to, if they haven’t already, fall to their doom in Earth’s atmosphere. https://www.engadget.com/nasa-geomag...8.html?src=rss |
