There is better detail in the story here:
https://www.space.com/spacex-starlink-satellites-lost-geomagnetic-storm

There is more to the story I imagine.  It isn't clear why they couldn't leave "safe mode".  Was this a design issue?  Were the spacecraft at a point that their propulsion system couldn't recover them?

There will be more details in the weeks to follow.  Starlink has to provide information to keep financial investors interested.

The spacecrafts use Hall thrusters to maneuver.

Thank You both for the links. Shall print them here @ the library, take them home & read them. Until then I invite you to listen to the following (I own the whole cd & have listened to it so often It's totally memorized in my recall mem.)

I rarely do this-a separate posting on same subj... perhaps this has been discussed on hfu b-4: An inhanced visual of ALL The F***ING Space Junk circling Our Home!   ::)  ::)  nuff said!! !! Any takers/contributors?

Though the dots that represent objects in space swarm around the Earth, the space junk situation is not as dire as it may appear. The dots are not to scale, and space is a very big place.

    I just noticed the article specifically states it has not been updated since originally published-2009. (I'm paraphrasing).

The Kessler syndrome (also called the Kessler effect, collisional cascading, or ablation cascade), proposed by NASA scientist Donald J. Kessler in 1978, is a scenario in which the density of objects in low Earth orbit (LEO) due to space pollution is high enough that collisions between objects could cause a cascade in which each collision generates space debris that increases the likelihood of further collisions. In 2009 Kessler wrote that modeling results had concluded that the debris environment was already unstable, "such that any attempt to achieve a growth-free small debris environment by eliminating sources of past debris will likely fail because fragments from future collisions will be generated faster than atmospheric drag will remove them".  One implication is that the distribution of debris in orbit could render space activities and the use of satellites in specific orbital ranges difficult for many generations.

UmKay, one more thought 'bout Mr. Musk's "accidental" contribution...could a Mal-ware Hacker (Choose your favorite country/UNo what Eye mean!  :-X ) possibly have contributed to the "accident"? Just a suggestion?
