There's a VH3 KX and yes, that's right. And they either come down or they end up colliding up there and causing more debris or just hazard. And the other aspect of this as well with climate change, and even with particularly when we get solar storms and our planet's atmosphere, the outer atmosphere starts getting buffeted by the solar wind. It heats up. It will heat up and as it heats up, the thermosphere will start to expand. And as it expands, it's further out of the station. Some of that expansion goes into the orbital plane of some of the lower orbiting satellites. And what happens then is that the atmosphere is expanded up that far. That increases the drag on these satellites and that slows them down. So unless they can compensate and raise the satellites up anticipating this expansion of the upper atmosphere, those satellites can get dragged back down to Earth. So not only do they have a lifespan of let's say around five years before they start coming down, they also have to contend now, all satellites have to contend now with the atmosphere as it expands and contracts.
