A solar storm semi-nuked the Intelsat's Galaxy 15 satellite last month, enough so that it's not talking to Earth but it also isn't completely dead. So now it's wandering around the geostationary arc still broadcasting and about to mess up other satellites in its way:
"In what industry officials called an unprecedented event, Intelsat's Galaxy 15 communications satellite has remained fully "on," with its C-band telecommunications payload still functioning even as it has left its assigned orbital slot of 133 degrees west longitude 36,000 kilometers over the equator.
The first satellite likely to face signal interference problems from the adrift Galaxy 15 is the AMC-11 C-band satellite owned by SES of Luxembourg and stationed at 131 degrees west, just two degrees away from Galaxy 15's starting position."
If nothing can be done to stop it, Galaxy 15 will continue beyond AMC-11 and go on to torture other nearby satellites until it stops pointing at Earth...eventually. No one knows when that will happen, so Galaxy 15 could be causing havoc for quite awhile.
When it does finally die it will join about 160 other so-called "zombiesats" that are dead but still shuffle around the planet aimlessly searching for brains.
Galaxy 15 is near and dear to my heart because it was one of the satellites that carried Syfy's signal. So long old berserk, crazy friend...

The World Economic Forum asked “leaders from business, government, academia and nongovernmental and international organizations” to take a survey on the potential risks and benefits of different emerging technologies. They seemed to think the space technologies will have little benefit and pose little risk. Energy capture, storage, and transmission has the great promise and little […]
The graphene temporary tattoo seen here is the thinnest epidermal electronic device ever and according to the University of Texas at Austin researchers who developed it, the device can take some medical measurements as accurately as bulky wearable sensors like EKG monitors. From IEEE Spectrum: Graphene’s conformity to the skin might be what enables the […]

Although there will never be a consensus about the best way to make coffee, any coffee connoisseur will agree that controlling the grind of your beans and balancing water temperature are the keys to a tasty cup. Since your plastic coffee pot doesn’t really allow for that kind of customization, going back to the French […]
