If you’ve ever gazed in wonder at some of the spectacular timelapses from the International Space Station, there’s a good chance it was captured by NASA astronaut Don Pettit. Don has photographed the Earth from space extensively during several missions to the space station. Late last year I spoke to him about one specific phenomenon that he’s imaged from orbit – the aurora. The interview has now been released by Sky at Night Magazine as a podcast and you can listen to it here, or with the audio player embedded below. And if you want to get a sense of what it’s like flying over the aurora, have a look at some of the stunning videos over at NASA’s Gateway to Astronaut Photography.
