SpaceX loses 40 Starlink satellites to a geomagnetic storm
geomagnetic storms as periods of"rapid magnetic field variation" typically caused by a strong surge of solar winds.
These storms can be damaging to electronics and satellites in orbit. In this particular case, it warmed up the atmosphere and caused atmospheric drag — or the friction acting against the satellites' movement — to increase up to 50 percent higher compared to previous launches. SpaceX explained that its Starlink team tried to save the newly deployed satellites by putting them in safe mode, which adjusts their movement so they'd fly edge on like a sheet of paper, to minimize drag.
The deorbiting satellites pose no collision risk, SpaceX said, will completely burn up as they re-enter the atmosphere and will create no orbital debris. No satellite parts are expected to hit the ground."This unique situation demonstrates the great lengths the Starlink team has gone to ensure the system is on the leading edge of on-orbit debris mitigation," the company wrote in its announcement.
SpaceX has launched over 2,000 Starlink satellites as of January this year for its first-gen constellation. Launches with Starlink satellites as payload have become a routine for the company, and they'll become even more common if it gets approval to form a second constellation with up to 30,000 satellites meant to provide global internet coverage.
While Starlink could provide internet connection even to people in far-flung locations, astronomers said megaconstellations have become a worse threat to their studies than urban light pollution. In fact, the International Astronomical Union has justthe Center for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference.
