NASA has released a high-definition image of the Earth it calls Blue Marble 2012.
A ‘Blue Marble’ image of the Earth taken from the VIIRS instrument aboard NASA’s most recently launched Earth-observing satellite – Suomi NPP. This composite image uses a number of swaths of the Earth’s surface taken on January 4, 2012. The NPP satellite was renamed ‘Suomi NPP’ on January 24, 2012 to honor the late Verner E. Suomi of the University of Wisconsin.
The original Blue Marble image was taken in 1972 by astronauts aboard Apollo 17. Until today, it was my desktop image. NASA has made the new image available for download in several sizes. Link to story. Link to image.
