Apollo: Recreating the Iconic Earthrise Photograph"
The famous Apollo 8 photograph known as Earthrise, as well as
two others taken at about the same time, document the moment
when the Earth was seen for the first time by human eyes over
the horizon of another world. Until recently, space historians
and the astronauts themselves disagreed about exactly how these
photographs came about, including the identity of the
photographer. Decades-old debates about Earthrise were finally
settled by a visualization that used feature film computer
graphics software, Apollo trajectory documents, and data from
historical and current NASA spacecraft to accurately recreate
the moment when the Earthrise photo was taken. As the 50th
anniversary of Apollo 8 approaches, this talk will describe both
technical and personal aspects of the making of this
visualization and the questions that it addressed.
