Whole Earth images, Does any satellite provide regularly updated ones? Options

[elakdawalla]

There are tons of Earth observing satellites producing gorgeous detailed images, but I'm trying to figure out if any of them is capable of producing full-globe images of Earth on some regularly updated basis. Does anyone here know of such a beast? Are there weather monitoring satellites that do this?

The fundamental problem is that there are no spacecraft that can usefully image the "whole" earth beyond geostationary orbit. From 22 thousand miles out, they see to a horizon of something like 82 north and south (and the same east and west of the subspacecraft point) It's easy to imagine the view as a hemisphere, but a matched view to something from at or beyond the moon would show the difference.

Somebody should be able to match up geostationary global data to Messenger or the failed Japanese Mars orbiter or some such mission to get a quasi simultaneous match and maybe fake it using global mosaic data to show the geostationary view you'd have directly below the deep space mission.
