Well, that was awesome. The NPP Earth observation satellite launched successfully an hour or so ago, and I was with a chilled but thrilled crowd of a few hundred people to watch it at Vandenberg Air Force Base.
I'm (hopefully) headed to the launch of a Delta II (the last currently scheduled Delta II!) at Vandenberg Air Force Base, as one of only 20 people selected to participate out of more than 600 who registered.
It should give you a feeling of déjà vu: a defunct satellite's orbit is decaying, and because that orbit is circular it's going to be impossible to predict where and when along its ground track it's going to happen.
Unless you've been living under a rock you've probably heard that a very large Earth-orbiting satellite is going to be reentering Earth's atmosphere soon, and there's a small but nonzero chance of debris coming down where somebody might actually find it.
I wrote the following blog entry about an image from Japan's Daichi Earth-observing orbiter last week as one to keep in my back pocket for a day when I was too busy to write, not anticipating that there'd soon be a more pressing reason to write about Daichi. On April 21, after just over five years of orbital operations, Daichi unexpectedly fell silent, and is probably lost forever.
