A couple of evenings ago, we were able to watch the ISS, very high in the south, leaving the sunlit firmament and diving into the Earth's shadow, briefly glinting a fading rosy hue, then disappearing. We tried to imagine what sunset looks like to the crew. I suppose they get the chance to see it (and sunrise) well over a dozen times every day! Last night it sang a song to the moon, which was glowing through high cloud wearing a gorgeous multicoloured corona.
