Got yet another pin for my collection. This one marks the end of the CloudSat mission / spacecraft, which is shutting down after almost 20 years in orbit and quite a few discoveries about how clouds affect the Earth's climate. This one is a pretty nice one, with good detail on the solar panels and spacecraft body. Two metal layers, the upper one fitted into a dug-out area on the lower one, give the pin a lot of texture too, as well as a bit of heft.
