Two interesting sets of images have appeared from NASA of relevance to this post. Firstly, the BBC has published images of the Earth from the space agency vaunted as the most true colour versions available. They are here. These pictures are from the Modis device on the Terra satellite, stationed 700km above the surface of the planet and are used to advertise the Blue Marble set of images, available on Flickr.
The second set of interesting images from the agency are available through the Gateway to Astronaut Photography of Earth. This (which I’ve mentioned before) has had a bit of a publicity boost recently with the twittering antics of JAXA ISS astronaut @Astro_Soichi, presently using the newly installed broadband connection between the station and the ground to feed images home.
