The NASA Artemis Program will see humanity live sustainably and work on the Moon. To celebrate, NASA will feature images/selfies from people across the world on a 3D mosaic sculpture representing their future plans. The images will be colour-matched, printed, and added to the sculpture by hand at the 70th International Astronautical Congress in Washington, DC on 21st to 25th October 2019.
