Pale Blue Dot is a photograph of planet Earth taken on February 14, 1990, by the Voyager 1 space probe from a record distance of about 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System.
Would it be possible to take another Pale Blue Dot image using New Horizons? Will the apparent size of Earth be again smaller than a pixel? February 14, 2020 would be pleasant date.
Of course all images taken of Kuiper belt objects should be transmitted to Earth before.
