"Museum of the Moon" artwork by Luke Jerram, as viewed at the Durham Cathedral installation, October 2021. The audio sound effects on this are not part of the exhibition, but added by planetqwerty (c). From https://my-moon.org/about - Measuring seven metres in diameter, the moon features 120dpi detailed NASA imagery of the lunar surface. At an approximate scale of 1:500,000, each centimetre of the internally lit spherical sculpture represents 5km of the moon’s surface. The massive 23meter wide, high resolution image used to create the moon artwork, was created by the Astrogeology Science Centre in the USA. The imagery was taken by a NASA satellite carrying the Lunar Reconnaissance Orbiter Camera launched in 2010.
