Imagery collected by Vantor’s WorldView-3 satellite about 1 day after the anomaly shows that @starlink Satellite 35956 is largely intact.  The 12-cm resolution image was collected over Alaska from 241 km away.  We appreciate the rapid response by @vantortech to provide this imagery.  Additional data suggest that there is a small number of trackable debris objects from the event, and we expect the satellite and debris to reenter and fully demise within weeks.

On December 17, Starlink experienced an anomaly on satellite 35956, resulting in loss of communications with the vehicle at 418 km. The anomaly led to venting of the propulsion tank, a rapid decay in semi-major axis by about 4 km, and the release of a small number of trackable low relative velocity objects. SpaceX is coordinating with the @USSpaceForce and @NASA to monitor the objects.   The satellite is largely intact, tumbling, and will reenter the Earth’s atmosphere and fully demise within weeks. The satellite's current trajectory will place it below the @Space_Station, posing no risk to the orbiting lab or its crew.   As the world’s largest satellite constellation operator, we are deeply committed to space safety. We take these events seriously. Our engineers are rapidly working to root cause and mitigate the source of the anomaly and are already in the process of deploying software to our vehicles that increases protections against this type of event.

$BKSY captured a stunning shot of L-15s in action at Dubai Airshow and our AI-powered analytics detected the aircraft. This is real-time, space-based intelligence at work.

"Just a few months ago, Spain and Portugal spent three days without electricity. And there is a suspicion that at least part of what happened there was a solar flare that caused a bit of a voltage disturbance in the grid and literally shut the whole country down." - Graeme Codrington, futurist and partner - TomorrowToday Futures Institute #TheMoneyShow buff.ly/VHyELNX

Holy cow, atmospheric conditions today for VHF propagation is something else. That is over a 1000 km for an AIS message.

@WeldPond This looks interesting thanks. Also reminds me of the book Normal Accidents by Charles Perrow

Free 300 page ebook - "Rational Accidents: Reckoning with Catastrophic Technologies" Looks like there may be some lessons for software security here.

Starship flip maneuver and landing burn on its fifth flight test. Vehicle improvements ensured flaps were protected from high heating, resulting in a controlled entry and high accuracy splashdown at the targeted area in the Indian Ocean
