Terraced steps leading up to a lunar temple atop the Moon's Shackleton Crater. Artist Jorge Mañes Rubio, part of ESA’s future-oriented Advanced Concepts Team (ACT), has designed a place of contemplation to serve a future lunar settlement. It would be built on the sunlit rim of 21-km diameter Shackleton Crater, which is bathed much of the time in sunlight while overlooking a 4.2 km-deep interior mired in perpetual shadow. An app allowing people to virtually experience the Shackleton Crater environment for themselves is being finalised, meanwhile an animation is already available.
