That’s a somewhat newer mission patch from the National Reconnaissance Office, the spy satellite outfit which is clearly still at the top of its game. The amateur NRO watchers are still watching. I follow some of them on Twitter. Lately they’ve also been watching: the Starlink satellites, the launch of international asteroid probes, pretty pictures […]

Happy New Year, for what a year is worth given the light of Betelgeuse fading from the shoulder of the constellation Orion.

By the time you read this post, 2020 will have already arrived at the South Pole. Even if you read it the instant it pops up on the Internet, at 7 a.m. EST December 31, 2019, the New Year will already be an hour old. You don’t have to go to the South Pole to […]
