Fwiw, there's also a set of monthly Blue Marble Next Generation[1] (2004), similar to the single Blue Marble (2002) used by clouds.matteason.co.uk. Snow cover is quite visible[2] - perhaps undesirable for a "are there clouds there?" ISS application, but nicer for a "loosely approximate Earth appearance". I used it years ago for an Earth seasons interactive - perhaps there's some way to get actual snow cover these days, rather than echoing 2004's snow? And more realistic ocean color?
Ah, nice. A quick thought: Perhaps have an option of seeing a projected track, perhaps with time ticks, for "oh, it's going to overfly mumble in mumble time - I should stay/try to come back then"?
