When it finally occurred to NASA (with persistent nudging by Stewart Brand) to turn their satellite cameras back on Earth, from whence they came, our planet took its first self portrait. That picture of the whole Earth became a catalyst for human environmental consciousness. It is now the emblem of our home.
Although there have been a few crude animations of a video version of this self-portrait since then, the following Whole Earth Video -- with Moon transit -- is quite handsome.
The still-unlaunched L1 point satellite DSCOVR would display a continuous year-round real-time image of the earth in full sunlight. It would be a mirror in space. Watching in multi-spectrums, this full-time eye would make video of earth a never ending webstream. Bush-politics have shelved plans to launch the $100 million completed bird now sitting in a warehouse. Maybe Obama can get it up where it belongs. Or at least release the FOIA-denied documents on why it was killed.
