When Galileo developed the first telescope in late 1609, he turned and pointed it to the Moon. He made the discovery that its surface was not the smooth sphere that everyone had imagined, but that it was actually covered in mountainous and basin shaped depressions. It wasn't until 1791 that a German astronomer Johann Hieronymus Schröter named them craters.
That is what Lucy saw when she created this backdrop. A backdrop that looks deceptively textured just like the unconventional Luna Crater in Kutch in India.
