{"date":"2025-05-18","explanation":"What if you could fly over Pluto -- what might you see? The New Horizons spacecraft did just this in 2015 July as it shot past the distant world at a speed of about 80,000 kilometers per hour. Images from this spectacular passage have been color enhanced, vertically scaled, and digitally combined into the featured two-minute time-lapse video. As your journey begins, light dawns on mountains thought to be composed of water ice but colored by frozen nitrogen.  Soon, to your right, you see a flat sea of mostly solid nitrogen that has segmented into strange polygons that are thought to have bubbled up from a comparatively warm interior.  Craters and ice mountains are common sights below. The video dims and ends over terrain dubbed bladed because it shows 500-meter high ridges separated by kilometer-sized gaps.  The robotic New Horizons spacecraft has too much momentum to ever return to Pluto and is now headed out of our Solar System.","media_type":"video","service_version":"v1","title":"Pluto Flyover from New Horizons","url":"https://apod.nasa.gov/apod/image/2505/PlutoFlyover_NewHorizons.mp4"}
