From Christian Davenport:

I'm fascinated by the Space Force and remember hearing a top Pentagon official talk about the threats in space years ago. He recalled the general panic over Sputnik, in 1957, which was little more than a ball with a radio transmitter, and said that if the American public were paying attention to everything going on in space today--even the unclassified activity--there would be that level of concern. Now, the threats in space have come to the forefront, and we saw in late 2021 how Russia blew up a dead satellite creating a massive debris field. We've also seen in Ukraine, the rise of commercial satellite imagery playing a huge role and test the rules of warfare. I wrote a lengthy story about this. SpaceX's Starlink Internet constellation has also given Ukraine a big boost that has helped its military tremendously.
