Quote:The U.S. Space Force is tracking debris in space after a satellite manufactured by Boeing exploded earlier this week, the satellite's operator said.

The Intelsat 33e satellite, which was launched in 2016 and provides communications across Europe, Asia and Africa, experienced "an anomaly" on Saturday, Intelsat said in a news release. Attempts were made to work with Boeing and repair the satellite, but on Monday, the U.S. Space Force confirmed that the satellite had exploded.

The satellite's breakup left some customers without power or communications services. Intelsat said it is working with third-party providers to limit service interruptions, and is in communication with customers.

Since the breakup, the U.S. Space Force is now tracking "around 20 associated pieces" of the satellite in space. The agency said that there are "no immediate threats" and routine assessments to ensure safety are ongoing.

Russia's space agency, Roscosmos, said it had recorded "more than 80 fragments" of the destroyed satellite. Analysis of the pieces' trajectory determined that the destruction of the satellite was "instantaneous and high-energy," Roscosmos said.

Quote:The explosion of space weather research since the early 1990s has been partly fueled by the unprecedented, uniform, and extended observations of solar disturbances from space- and ground-based instruments. Coronal mass ejections (CMEs) from closed magnetic field regions and high-speed streams (HSS) from open-field regions on the Sun account for most of the disturbances relevant to space weather. The main consequences of CMEs and HSS are their ability to cause geomagnetic storms and accelerate particles. Particles accelerated by CME-driven shocks can pose danger to humans and their technological structures in space. Geomagnetic storms produced by CMEs and HSS-related stream interaction regions also result in particle energization inside the magnetosphere that can have severe impact on satellites operating in the magnetosphere. Solar flares are another aspect of solar magnetic energy release, mostly characterized by the sudden enhancement in electromagnetic emission at various wavelengths—from radio waves to gamma-rays. Flares are responsible for the sudden ionospheric disturbances and prompt perturbation of Earth’s magnetic field known as magnetic crochet. Nonthermal electrons accelerated during flares can emit intense microwave radiation that can drown spacecraft and radar signals. This review article summarizes major milestones in understanding the connection between solar variability and space weather.

So you're thinking tit-for-tat?

Oh and Starlink definitely can double as a kinetic disruptor, right? Does anyone doubt that? But perhaps not as high-energy yield as this event...

And hitting a geosynchronous communications satellite instead of a military satellite wouldn't send much of a message.
