This app from NASA's EOSDIS provides the capability to interactively browse over 600 global, full-resolution satellite imagery layers on desktop and mobile devices. Many of the imagery layers are updated within three hours of observation, showing the entire Earth as it is "right now". This supports time-critical applications such as wildfire management, air quality measurements, and flood monitoring. Some satellite imagery layers span almost 30 years, providing a long term view of our dynamic planet. The underlying data is available for download, and Arctic and Antarctic views of several imagery layers are available for a “full globe” perspective.
