Mercury’s Horizon

Mercury's HorizonNasa’s Messenger team haven’t added a ‘goodbye to Mercury’ video yet to add to the previously noted collection, but they have added plenty of stunning images from Messenger’s second fly-by of Mercury on 6 October. The BBC report includes a selection of images and the full gallery is available here – also see here. I’ve used this image of the view over Mercury’s horizon.
