50th Anniversary of the Earthrise Shot

December 24 is the 50th anniversary of the first photo of Earthrise from the moon. Apollo 8, the first manned mission to the moon, entered lunar orbit on Christmas Eve, Dec. 24, 1968. That evening, the astronauts -- Commander Frank Borman, Command Module Pilot Jim Lovell, and Lunar Module Pilot William Anders -- held a live broadcast from lunar orbit, in which they showed pictures of the Earth and moon as seen from their spacecraft. One of those photos showed Earthrise for the first time.

On this celebratory occasion, we are doubling down on the idea of Blue Marble Evaluation, an approach and framework for evaluating global systems change initiatives. Global challenges like climate change, global economic interdependence, and the global food system operate beyond national borders. Global systems change initiatives are intervening from the perspective of a complex, dynamic, and interconnected world system. Blue Marble evaluation is needed to assess the effectiveness of global systems change initiatives. If you are interested in becoming part of the Blue Marble Evaluation Network, please take a few moments to complete a brief survey to help us grow this important work.
