Here's a colorization of this LRO Earth image. Below is a preview at 10% resolution, 1/2 res version is available here (2.3 MB) and full res version here (8 MB).

The full version is extremely impressive! I can see clearly where I'm at the moment with some details, lake Chungara south East of Lake Titicaca.

Interesting post on gizmodo about data coming from a Russian weather satellite:

Hey Stu, check out this animation (from Early Precambrian to present):

Very cool as well, Mike! However, I think that the last image in the animation is probably of the end of the last ice age or so; the Red Sea is much larger, and it looks like the central Asian seas are still merged together.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Good catch! It is indeed the Neogene-Miocene period as the last step in the animated gif. The work that Stu originally referred to was done in collaboration by Dr. Ron Blakely of Northern Arizona University. (The animations in the wikipedia entry were done by Dr. Ron Blakely.)

Here is his website that has individual maps of each of the paleo-reconstructions (including Pleistocene and Present) :
http://jan.ucc.nau.edu/~rcb7/mollglobe.html

And a website to other detailed data products:
http://cpgeosystems.com/index.html


I recently got a copy of his (beautifully illustrated) book: "Ancient Landscapes of the Colorado Plateau", mentioned on his site. I highly recommend it.

Animation created from simultaneous views of Earth from five geosynchronous weather satellites taken every six hours starting on March 21, 2011:

A few more images of Elektro-L, the Russian geostationary weather satellite can be found here (among others, like Resurs-DK and Meteor-M):

Chandrayaan-1 view of the Earth during the solar eclipse of July 22nd, 2009 revisited. Very noisy, 4 visible channels of M3 centered at 620, 580, 540 and 500 nm were processed into this approximately natural color view. The 460 nm channel was useless. The way the M3 instrument scanned, the resolution in the vertical axis is much higher than horizontal.

Wow, really cool. There is a ghost image of Earth about three diameters to the right of the actual image -- do you know what causes that?

There's a whole bunch of artifacts visible there. Don't know about that specific ghost, I would assume this is optics related. I noticed imaging spectrometers of this type (pushbroom), VIMS visual channel included have subtantial stray light leakage both in the vertical and especially horizontal direction. You can notice the hot pixel columns get brighter left and right of a bright object. I deliberately left all this crud in to make it clear the other non-removable artifacts, such as vertical discolorations on Earth's disc are in fact artifacts and not real.

I should point out this was done using the raw data, of all the M3 images there are archived this one was not provided in a calibrated form. Perhaps because it was a one-off observation. I had to do manual bias subtraction and rudimentary "I/F" conversion. The whole M3 swath actually included another Earth image higher up, vertically flipped. I presume it was taken when the s/c was slewing back and judging by Earth's rotation it was taken a couple of minutes later. I can post a flickr gif of the two, but it's nothing spectacular.
