Mapbox: up-to-date satellite imagery

Google Maps and similar services are most useful, but who has the most recent space footage of your neighborhood? Check out mapbox, a Landsat viewer that tells you when the satellite image you're looking at was taken, and when a new snap is scheduled. The zoom level really isn't useful for anything at a life-lived level – with the exception of recent weather, disasters, etc – but all services should expose metadata like this.
